Abstract
ICTs represent strategic resources for Cultural Heritage (CH) projects. Anyway, several conditions put the success of promotion projects at risk, especially if carried out at the local level. Firstly, local scale amplifies the weight of budget constraints on the priorities of public administrations, compelled to allocate funds to the physical conservation of heritage rather than to software and training. Secondly, proprietary SW, often sophisticated and complex in procedures, fails to integrate precious unformalized knowledge from local stakeholders and communities, particularly in the field of cultural tourism. Finally, a changing demand for cultural tourism, with potential visitors frequently searching for information directly on the Web before moving, requires a higher interactivity in tools and systems. The paper illustrates the work carried out at the Construction Technologies Institute for delivering procedures and SW specifically designed to simplify the publication of geo-referenced information and reduce the need for specialized skills and equipments. The described results were achieved along different research programs focusing on the Albanian CH with a learning-by-doing approach. © 2012. Published by Elsevier B.V.

related programs is more than acknowledged. Nevertheless, since any process addressing cultural resources is complex and involves well-differentiated activities and objectives, ICTs for Cultural Heritage can not be considered as a single domain, but should be dealt with, more properly, by purpose-driven areas, refining research efforts accordingly.
Undoubtedly, when compared to the phases of collection and cataloguing of knowledge on heritage, presentation and dissemination tasks represent more dynamic steps, potentially able to trigger territorial development by boosting visit-related activities, tourism in the first place.
Among its main activities, our Institute has been carrying out transnational cooperation experiences in the Mediterranean basin under several EU programs; some of these focused on the Albanian heritage promotion.
Though among the smallest countries of Europe, Albania owns a rich and variegated cultural history, with a still vivid tradition. In the whole territory, about 2400 architectural monuments are to be found, such as castles of the ancient and Medieval periods, fortifications, rural constructions, cult monuments as well as iconographic works, post-Byzantine frescos, etc., not to mention archaeological centers and ‘museum cities’ (Butrint, Apolonia, Durachium, Bylis, Berat, Gjirokastr, Krujë, etc.).
All this heritage has long suffered from neglect due to political and economical reasons, but recent efforts in collecting knowledge on sites and their actual state of conservation are being made among regional agencies in a positive attempt of cultural identity awakening, with thousands of photos, drawings and maps accompanying their reports to the central government.
A first map reporting the status of buildings in 50 sites (fig.1) was developed within the ‘A3C - Albania: Conoscere, Comunicare, Condividere’ (Albania: Know, Communicate, Share) cooperation project (INTERREG III-A FESR/CARDS Italy - Albania 2004/2006 Proximity Program). The activity was particularly time-consuming due to the acquisition and geo-referencing of maps as well as to the development of the interactive map, so an authoring system to facilitate the interface development was planned.

In such a context, where diffused ‘minor’ assets far exceed the number of single masterpieces, whole regions can be identified as ‘local museums’ in themselves, the success of which generally depends on their ability to be integral part of a community, rather than mere ‘tourist attractions’. It is crucial, then, to deliver simple and easy-to-use management and promotion tools mainly to local municipalities, enabling them to make their heritage an active resource for social and economical development.
Open Source technologies, such as those implemented at ITC-CNR, offer a two-fold efficacy. On one hand, they match typically operational problems that require easy-to-implement solutions, as is the case with huge quantities of sites to be located, mapped and presented. On the other hand, OS software hits the main target of the latest European Framework Programs and markedly of the ‘Heritage for All’ initiative, whose basic principle, the creation of communities able to autonomously create and document “the digital record of their own societies” and grant their future accessibility [1], quite naturally leads to orientate research towards technologies with specific ‘enabling’ value, up to supporting ‘user created content’. Open source technologies, then, are not just ‘convenient’ for low cost and ease of use; indeed, their effectiveness is farther-reaching. European projects for cultural heritage of the last years – such as CHIMER, CIPHER, COINE – have been focusing on solutions that support ordinary people and communities in building the “living picture of regional heritage across Europe” [2], while at the same time promoting cooperation and exchange. OS technologies, then, will become increasingly central in projects for the heritage, also to the benefit of specific objectives such as technology transfer and capacity building as well as social inclusion and enlarged fruition in relation to weaker user groups.
With specific reference to the issues of visualization and presentation of cultural resources and sites and in line with the areas of interest pointed out in the European Research Network on Excellence in Processing Open Cultural Heritage (EPOCH) Research Agenda [3], the work of our institute focused on the elaboration of an authoring tool in order to support non IT-specialist users in the presentation of assets for promotion purposes. Further work addressed the realization of appealing, interactive virtual tours of resources, in order to capture the interest of as many as possible potential visitors. A specific attention was paid to interactivity of tools, in order to capitalize usability and user experience, which represents a specific concern area for future research; indeed, a greater involvement of end users is seen as decisive for a significant penetration of ICTs in the CH sector [3]. The developments described in the following, started within the above mentioned ‘A3C - Albania: Conoscere, Comunicare, Condividere’ cooperation program, are proceeding and under refinement, with new functionalities, within the ‘SOS – Shqiperia Open Source’ program, in conjunction with IMK (Instituti i Monumenteve te Kultures), the Institute for Monuments of Tirana in Albania. The project aims at promoting the growth of operational skills among IMK staff involved in the Albanian cultural heritage promotion, thus contributing to the development of initiatives in the tourism sector, with potentially remarkable results since tourism and culture activities as well as IMK are managed by the same Ministry. Project activities are generally carried out in a ‘learning-by-doing’ modality, in order to maximize both know-how transfer and the development of related skills. The project conclusion is due in February 2014.
2. The Authoring System for Interactive Map Generation
There are many commercial suites that offer authoring platforms for creating and customizing Web-based tools in the field of geomatics. They are often a collection of several instruments, typically desktop applications, which allows to create geo-referenced content, change the layout of presentation in a Web page and to facilitate its publication. After an extensive review of solutions offered in WebGIS authoring platforms [2], both Open Source and proprietary, we can state the innovative character of an integrated WebGIS authoring application, completely Web-based and therefore accessible and usable simply with a Web browser, that allows the creation of a totally customizable and editable WebGIS application.
386 Davide Di Pasquale et al. / IERI Procedia 4 ( 2013 ) 383 – 390
Fig. 2. The system’s UML Class diagram
The developed prototype makes use of AJAX (Asynchronous JavaScript and XML), with the open source JavaScript library OpenLayers API (http://openlayers.org) for rendering geo-spatial data within a Web browser. To meet the demand for simple system's installation, all data are stored in an XML file rather than in a database (which would require the installation of a DBMS if not already present on the server hosting the system), except for the geo-referenced data, stored in GeoJSON (Geographic JavaScript Object Notation) format. GeoJSON is a specialization of the JSON data interchange format that can manage geo-referenced data using a subset of instructions provided by the JavaScript language. For the implementation of the editing environment, characterized by a high degree of interaction a JQueri UI library was adopted: it is based upon Jquery, a more general Javascript library providing a high level of abstraction for programming interaction and animation, advanced graphic effects and customizable event handling. The same was also used for the implementation of the WebGIS interface instance and for the resulting WebGIS environment, with easy-to-use tools for map navigation and information search. The class diagram in Fig. 2 gives an overview of the overall system architecture by showing the relations between the different software components and how they rely on each other. The main class is the User Interface class, a generalization of the two subclasses Design Environment (representing the authoring system) and Use Environment (representing the WebGIS).
All the graphical widgets in the interfaces users can interact with, such as icons, buttons, text fields and
387 Davide Di Pasquale et al. / IERI Procedia 4 ( 2013 ) 383 – 390
text labels, are localized according to the preference each user indicates, and customized on the basis of the role of each user, i.e. a Web publisher, a content manager and so on. The user interface localization process is performed by the Localization engine, which lets users decide the interface language. In contrast, the customization engine acts automatically on the user interface: it presents widgets and data coherently to the user’s role and the to the environment invoking it.
The Annotation Engine allows to create and recall annotations produced by the system’s actors. Web publishers can annotate the data organized by content managers if they find errors or if they need some kind of information that has not been produced. By doing so, content managers can retrieve these annotations and correct the problems. At WebGIS level, final users can add geo-referenced annotations to the map they are browsing, or read annotations left by other users; this allows them to share their impressions and experiences about places they have visited. Moreover, they can annotate the WebGIS instance itself, to communicate their needs, in terms of information or functionalities, to content managers and Web publishers.
The Data Manipulation Engine class implements, through the Data Aggregator, Data Storer and Data Retriever, all the functionalities to read, edit and write data according to each stakeholder’s role in the system.
The Data Aggregator is used to manipulate datasets and create new ones; this is particularly useful for homogenizing data gathered from different sources and for the creation of new ones, that will be saved in a suitable format by exploiting the Data Storer. The Offline navigation tool relies on this functionality to produce maps and file with the points of interests (POIs) to be downloaded by the users.
The Data Retriever, then, manages the access to already stored data. The Renderer class is specialized into four different subclasses, each of them taking care of rendering, mostly in the WebGIS, different geo-referenced graphical elements: the map, the POIs, the routes and the virtual tours. The Renderer relies on the Data Retriever to get geo-referenced data and annotations to be displayed in the WebGIS, and on the Data Storer to save annotations and temporary users’ routes.
The Functionalities Handler allows Web publishers to activate and configure the functionalities that will be offered to final users in the WebGIS (map zoom and pan, selection of points of interest, allow or deny annotations’ creation, route computation). At the same time, the Functionalities Handler is called in the WebGIS to actually implement the selected functionalities.
The Layout Editor acts as a graphical editor for the disposition of the functionalities and the information visualized by final users interacting with the WebGIS: Web publishers can build the WebGIS layout by dragging and dropping widgets associated to map’s browsing tools and visual elements such as page header, page layout and how final users’ requested information should be displayed.
Finally, the Search Engine, constituted by the Search Editor and the Query Editor, allows content managers to configure the search tool for final users. By exploiting the Search Editor, content managers can configure which geo-referenced data can be searched by final users and the way they are allowed to build their queries.
3. Interactive Map of Albanian Heritage
Subsequent steps have to be followed in order to generate the map: the planning of the places to be surveyed; the GPS survey of suggested access points, opening modalities (closed, open on request, open), accessibility status (accessible for all, accessible with constraints, not accessible); the generation of a file containing both the image information (exif data: latitude, longitude, image name, date) and the additional information inserted by the user (site name, image content, site type, data sheet URL).
First, the Authoring System reads the file and reports the fields; the user chooses the one suited for latitude and longitude, for classification and research purposes. Moreover, each field can be assigned a specific text.
Then the classification task is performed and special icons should be assigned to each type (an overturned water drop symbol – with different colors – is the default).
388 Davide Di Pasquale et al. / IERI Procedia 4 ( 2013 ) 383 – 390
Fig. 3. WebGIS interface under development using the authoring system (Openlayer version)
In the ‘map’ tab the system displays the Google map, allowing to locate the workspace, recording its centre and scale factor to be used when the user starts the WebGIS; in the ‘callout’ tab the user is allowed to specify the contents of the callout displayed when clicking on a point of interest, within a predefined layout.
Finally, an interactive map interface is generated automatically (fig. 3), organized into four sections. The ‘heading’ section presents the logo, title and subtitle assigned through the authoring system. The ‘search’ section – often absent in other systems – presents a text box for text insertion and a checkbox
for checking/unchecking of each typology. This function implements auto-completion to assist users in the search phase: when typing characters in the dedicated box, the system proposes and updates the list of those places whose search-enabled fields contain the typed text and whose typologies are checked in the communication tab, thus restricting the search field (default: all typologies checked).
The ‘communication’ section has two tabs: the ‘thematic map’ tab shows the available typologies, preceded by the same marker used in the map and a by checkbox for inclusion/exclusion of typologies in the map and in search sessions; the ‘search results’ tab shows the list of the points of interest complying with the search criteria, including thumbnails.
The ‘map’ section has an overview and three display modes (hybrid, streets, satellite); it allows users to interact with the Google map by:
reading the information associated to the place – by clicking on the icon, the system displays the previously designed callout containing links to both the photographic image and to a description;
navigating with ‘pan’ and ‘zoom’ tools; the latter automatically manages the overlapping of points of interest that occurs at reduced detail levels, by replacing the bunch of icons through a single predefined yellow icon reporting the total number of the points of interests grouped in it.
The interactive map currently developed for testing purpose refers to places in Albania where our Institute developed virtual tours within different international research projects.

Fig. 4. Virtual tour of Butrint
Virtual tours make the user feel immersed in any space, anywhere in the world, although it has never been there. It sets the user in the centre of a place in order to discover its details at the click of a mouse. Google Street View shows places from a pedestrian perspective; by using arrow keys or mouse, users can control their direction and tour speed; by moving an icon (representing the traveler) to a certain point, they can move to different places very quickly. Virtual tours are becoming an important means for remote fruition of sites; in the tourism industry they help travelers make better decisions (saving time and money) before purchase by providing them with vivid images of destinations – therefore it is an effective way to promote new or existing destinations [3]. In the culture sector they allow to visualize and investigate those places that, due to safety issues or impossible collective fruition, are kept closed or made unavailable to the public access. Moreover, virtual tours support – effectively and cheaply - small communities in the promotion of ‘minor’ cultural heritage doomed to perish without care and funds, raising communities’ awareness and attention towards artistic, cultural and environmental heritage – the examples shown here refer to the Butrint archeological site in Albania (fig.4).
The interface has buttons for navigation (‘enlarge/reduce’; arrows to pan the image by recurrently clicking; stop the image rotation), help about the use of the interface, restart, turn on/off hot spots on the image; switch on/off full screen; turn on/off map, start a guided tour, see place gallery and focus gallery.
The map is generally a graphical reproduction of a territory or building, with icons for each place involved in the virtual tour: by clicking the icon, the user jumps in the connected place. A “radar icon” – moving according to the actual image rotation – is positioned in the observed place. We used a Google map as in the WebGIS with an overview and hybrid, streets or satellite modalities.
390 Davide Di Pasquale et al. / IERI Procedia 4 ( 2013 ) 383 – 390
The guided tour starts navigation through places and focuses, according to a planned itinerary, allowing the user to have a comprehensive overview. It is not a video but a programmed synchronized loading of events, so the user can stop the guided tour anywhere, to start its own exploration of the place.
The place gallery is a preview of places shown in the virtual tour; the focus gallery is a preview of relevant details; by clicking on a preview, the virtual tour receives parameters allowing to start directly from that area – an innovative function available also with external link.
Three kinds of sensitive points - called “hot links” - can be found on the image: “navigational” (jumping in a connected place – as in the map, so giving the impression of moving within the space as it happens in real vision); “informative” (opening an info-box with text and a text-to-speech functionality); “focalize” (magnifying the view on a focus; an high resolution image is required, to be managed with a cache technology to reduce loading time); an hot link has a label, usable for search.
4. Conclusions
With specific reference to the issues of visualization and presentation of cultural resources and sites, the work of our institute focused on the implementation of an authoring tool in order to support non IT-specialist users in the presentation of assets for promotion purposes. The prototype adopts a KISS (Keep It Simple, Stupid) approach and using javascript “Openlayer” libraries, it generates a WebGIS application for the publication in the Internet of geo-referenced information acquired through a GPS camera. The implemented interface is illustrated using information on virtual tours in Albania developed within different international research projects: two challenging technologies that our Institute is enhancing with new functionalities.
On-field activities oriented to the acquisition of information about monuments and sites as well as the final testing of the prototype will be carried out by the staff of our partner – IMK - in a ‘learning-by-doing’ modality, in order to maximize both know-how transfer and the development of related skills.

AbstractSometimes the result of a search for cultural destination on the Internet
contains different kind of errors, mainly imputable to mistakes in user contribution, data input and software.
The paper illustrates a way to decrease these problems through proper procedures and software, named as ‘The Mu.S.A. Project’. Furthermore, the paper shows the interactive map developed for Tirana (an Android app for Smartphone) and for Cetinje (cross-platform).
Paper
INTRODUCTION
In the tourist context, nowadays, most people plans a trip carrying out a search on the Internet to locate the main Points of Interest (PoI). Moreover, the growing diffusion both of mobile devices equipped with GPS and flat rate data plans produce a larger use of mobile services. These considerations suggest to develop a tool usable on different devices in order to assist the user with the same interface not only in the planning phase, but also during and after the trip.
Taking into account that tourism is an activity strongly connected to the interests of people, a recommender system is doubtless to be considered in this tool.
Recommender systems are usually classified in two categories1, content-based recommendations and collaborative filtering; however, several hybrid approaches have been proposed to exploit the advantages of both methods. Anyhow, the recommender systems only request the user to flag as ‘like’ or ‘dislike’ an item to avoid boring the user.

Another topic to consider is that mobile technology using context-aware applications is useful to assist tourists in solving their problems, largely related to navigation and way finding, so the accuracy of a location on a map is significant.
The production of a map requires a number of steps, starting from initial survey and data collection through data manipulation, according on the task for which it will be used.
Each successive step can introduce inaccuracies due to: a) the limitations of the equipments; b) the human factors such as erroneous measurement or classification; c) the required generalization of the adopted scale; d) an inadequate budget for data completeness and map accuracy. The latter measures how closely the map represents a view of the real world and covers a number of issues mainly pertaining to the position of the locations and their attributes.
The positional accuracy relates to the quality of the results, its precision2 and resolution3; it can be estimated because each measure has an error value associated, so accuracy standard to respect have been produced for professional maps.
Unfortunately, maps intended for non-professional use occasionally present locations not properly placed on the map; main web mapping services allow users to send them enquires4 to rectify the data but, more often, wrong information continue to stand on the web.
The table n.1 shows some typical errors, related to a wrong user contribution (fig. 1), wrong data input (fig. 2) and wrong software (fig. 3); therefore, there is the need to find a solution to minimize this kind of errors.

THE MU.S.A. PROJECT
The answer to the above questions should be settled through proper procedures and software; our solution is the ‘The Mu.S.A. Project’, aiming to:
• Value selected community-defined contents; the goal is involving thestakeholders - as municipalities’ teams, cultural associations, secondaryschools - to ‘extract’ their knowledge about less known cultural andnatural locations, assuring a right user contribution. This main andqualified information should be successively enriched by the contributionof other users, by adding (to the database) multimedia contents and/orrecommending specific PoI using a like-button procedure.
• Develop a tool to manage the database - supporting data input andlocation placing using gps photo in order to reduce possible mistakes -and to produce an interactive map through a guided procedure.
• Share information through an interactive map full of tools assisting usersto find PoIs by surfing/searching, according to the user/group profile

(accessibility needs included), eventually supported with user location and users recommendations (like-button based).
This project consolidates experiences already developed in mapping. In effect, the team implemented in 2009 a plug-in for the open source ‘Quantum GIS’ to generate interactively a file containing the parameters required for the web-publishing of the GIS using Pmapper - another open source tool. This plug-in was used to produce the interactive map5 for the city of ‘Corfu’ which includes ‘Paleopolis’, exactly a Greek site investigated in the ‘T.He.T.A’ project. The activity was particularly time-consuming due to the acquisition and geo-referencing of maps as well as to publish the GIS on the Internet, so a procedure to speed-up the whole process was implemented, creating a first version of an authoring system. It was used to develop, among others, the interactive map of cultural heritage for the city of:
• ‘Corfu’, http://www.ba.itc.cnr.it/CORFU/CORFU.html (fig. 4);• ‘Gioia del Colle’6, http://www.ba.itc.cnr.it/GDC/GDC.html (fig. 5), with
a link to a sample virtual tour http://www.ba.itc.cnr.it/GDC/Distilleria.html;
• ‘Tirana’, http://www.ba.itc.cnr.it/SOS-Tirana/sos.html, with links toseveral virtual tours7.
The Mu.S.A. project was firstly presented at the road show of ‘Festival dell’Innovazione’ in Bari (6/3/2013); afterwards it was officially presented8 in Athens.
It is organized in an Advisory Assistant (AA) for the developing phase and in an Advisory System (AS) for the sharing phase.
AA is based on the photos taken with a GPS camera for each PoI selected by the stakeholders; the step-by-step procedure is as follows:
• Extracting latitude, longitude, image name and date registered in the‘Exif’ data of photos and saving them in a csv (comma separated value)

file – the team uses the freeware software ‘Exif extracter’ (http://www.br-software.com/extracter.html).
• Importing the csv file, adding further information according to theproject purposes9 and saving it in a dbf file – the team use the open source software ‘open office calc’ (http://www.openoffice.org).
• Opening the dbf file and generating the interactive map using a guidedprocedure developed by our team.
AS has two components: the interactive map and the user interactivity, tested with different devices (fig.6). The tools developed are:
• A desktop (fig. 7) and a totem version10 for the city of ‘Siracusa’- includingaerial (fig. 8) and terrestrial virtual tours11.
• An Android app version12 for the city of ‘Tirana’ in Albania.• An html5 version13 for the city of ‘Cetinje’ in Montenegro - including
terrestrial virtual tours with external link between tours.
The functionalities regarding the user interactivity, still under development, are:
• Social network behaviour (like/don’t like);• User contribution (photo, video);• User interface adaptability (profiles).
THE MOBILE APPLICATION OF THE ADVISORY SYSTEM
With screen sizes proliferating, the team built an adaptable interface that works well on both small and large screen resolutions. This allows devices with larger screens and better graphics cards to display a larger view of PoIs, while devices with smaller screens and less capable graphics cards still receive an

optimized presentation. Therefore, our approach to mobile development can be summarised as
follows:• For installed mobile apps, where performance and deeper access is
required, a native App was built, developing an application for the cityof ‘Tirana’ in Albania;
• For cross-platform PC and mobile web, an HTML5/Javascript solutionwas built, developing an application for the city of ‘Cetinje’ in Montenegro.

The interactive map of Tirana
The interactive map of Tirana is an App, generated by AA, organized into three sections (fig. 9): ‘List of PoI’, ‘Search’ and ‘Map’ (with overview and three display modes – hybrid, streets, and satellite).
All the three sections contain on the top a particular ‘heading’ that presents the logo, title and subtitle, assigned through AA and much more.This heading has been developed with the ‘The Action Bar’ (AB), an Android application element that offers users a familiar interface across applications that the system gracefully adapts for different screen configurations. AB is divided into three areas:
• The first is located on the left and contains the logo and title.• The second is located in the middle and contains an action button ‘Map’
that opens a view that handles the display of interactive map with zoomextension.
• The third is located on right and contains an action button that runs aseveral actions of the App and updates according to the current view.
After launching the App, the start page is opened for few seconds, allowing

150
the automatically updating of the contents published on the server if modified. After the start page, the App offers the user a scrollable list (Android
expandable list) containing all the PoI’s typologies generated by AA - the ‘List of PoI’ section. In this section, the user can displays all the typologies, such as Castle, Bridge and so on. Next to the heading of each typology, there is a button with a down arrow to allow the user exploding the list (under the heading of the chosen typology) and viewing, below, the list of PoI’s selected typology. Through this list, the user can access specific information of the various PoIs, proposed and grouped according to the different types.
Selecting the item relative to a PoI within the scrollable list, the user access another scrolling list named ‘list of Media’ containing links to media content available for the selected PoI. The use of scrolling lists makes information access much more intuitive and faster; these views, in fact, are optimized for touch screen mode.
The scrollable list, ‘List of Media’, allows the user to: • Display on the device the map centred on the PoI (‘To PoI on Map’).• View the information sheet of the selected PoI (‘To About PoI’).
Fig. 9. Android app for Tirana (S.O.S. project).
151
• View the virtual tour of the selected PoI, if any (‘Virtual tour’).Selecting the item ‘To About PoI’, the App opens a view that contains a
detailed information sheet of the selected PoI and reported on three pages, which are available by sliding finger across the screen horizontally. The three dots, at the bottom, indicate to the user in which of the three pages he/she is.
The ‘Search’ section, often absent in other systems, has a friendly interface based on a dialog box containing:
• A ‘Search’ textbox; typing a letter in the textbox, an interactive list ofPoIs containing that text is automatically generated.
• A back button opening the former screen.• A ‘search results list’ showing the list of PoIs complying with the search
criterions; thumbnail, title and short description are reported.
In the ‘Map’ section, the user interact with the Google maps in traditional modalities:
• Navigating with ‘pan’ and ‘zoom’ tools, the user can view more detailedelements of the map; furthermore the user, clicking the grey button on the top right corner of the map, centers the map on his/her location, viewing PoIs nearby.
• Clicking the markers, the user open the previously designed ‘callout’reporting info about the selected PoI (thumbnail with link to the photo, title, description) in a popup window above the map, at the specific location.
A ‘cluster marker’ has been introduced: if several PoIs are close, they overlap when the user zoom in the map with a lost of information. Beyond a predefined threshold, the overlapped markers are temporarily replaced with a cluster marker.
The interactive map of Cetinje
The interactive map of Cetinje is a cross-platform map solution developed using HTML5 and SVG in order to support full browser display, mobile devices, improved data handling, dynamic window resizing, Global Positioning System (GPS) integration, active state URLs for bookmarking, and much more.
152
Hundreds of traditionally native apps are turning into web apps as they provide advantages like interoperability, ubiquity and cross-platform: they can be accessed using PC, Mac, laptop, desktop, mobile device, smart watch, car and even home appliance. The features added in the new HTML5 standard allow a much more dynamic web content and the development of applications never before imaginable on the web, such as mapping, one of the most performance and resource demanding type of app.
The development of the map is based on the Google Maps API14 creating an engaging web and mobile application with Google powerful mapping platform, including satellite imagery.
After launching the App, a splash screen illustrates the Mu.S.A. project; the interface provides a heading containing the title between a menu icon and a layer icon.
The menu icon on the left (fig. 10) open/close a list of functions, including, among other things:
• ‘Best site’, opening a callout on a PoI selected by the stakeholders as themost interesting place to visit.
• ‘Satellite’, switching to the aerial imagery of the current map.• ‘Slideshow’, opening an image carousel at the bottom of the map – it is
one of the best ways to display information in a small space, enabling aquick selection of the interested PoI.
• ‘Time slider’, activating an interactive time slider on the left of the map;when the user drags the slider selecting a century, the PoIs in the mapare filtered on the age of building.
The layer icon on the right (fig. 11) maximizes/minimize a sidebar containing a navigation menu with a categorised list of PoIs, organized in a hierarchical structure: an accordion menu that only shows one panel at a time. Each panel has its own colour and marker, that represents a different type of building (Historic building, Monument, Museum, Religious building, Other) and a display with the total amount of PoIs for each type. A panel can be expanded/stretched to show/hyde a vertically stacked list of PoIs – a subpanel with a thumbnail, Title and Address.
An assisted search function is located on the top of the sidebar; when the

user types any words, the accordion menu is automatically updated, showing only the list of PoIs matching the typed text; moreover, the display shows the total amount of founded items.
Each panel could be filtered turning it off/on, hiding/showing in the map the PoIs of the selected type.
It is also possible to click on the ‘filter icon’ to open an advanced search panel (fig. 12), in order to select PoIs not only through text but also through their contents:
• Data, to select fields to search - Title (default), Address and Content.• Accessibility, to exclude PoIs with an ‘uneasy’ or ‘restricted’ access –
useful for impaired people.• Media, to filter the PoIs having video and virtual tour.• Century, to filter the PoIs depending on the age of building.
FUTURE DIRECTIONS AND CONCLUSIONS
The Mu.S.A. project is expected to strengthen the local institutions in promoting less known cultural and natural locations through the assisted implementation of an interactive map service with contents provided by stakeholders. Further tools and functionalities have been planned to enrich the interface as well as to meet different users’ requirements:
• Adopt Colour Universal Design to help ensure that graphical informationis conveyed accurately to people with various types of colour vision impairment, including people with colour blindness, focusing on ease of use from the user’s perspective rather than relying on the designer’s aesthetic sensitivity. The goal is to use a set of colours that is unambiguous both to colour-blind and non-colour-blind users, as well as using web-safe colours (solid, non-dithered and consistent on any computer monitor, or web browser).
• The above choise limits the classification of POIs to six items, so it willbe necessary to widen the sidebar functionality introducing sub-types management: different markers with a unique colour associated to each type and different images associated to each sub-type.
• Improve cluster marker: a) using different diameters, reported to thenumber of items grouped; b) switching it (passing a threshold) to an
155
interactive coloured bar graph marker displaying the item amount for each PoI’s type.
• Extend filter functions to: a) Provide a list of locations represented in themap, which are recommended by taking into account both the user’s preferences and the ratings of other similar users, giving GPS guidance to them, including an itinerary planning. b) Add a ‘Near me’ function to filter the sidebar only with locations the user find in a specified distance from its position or in the actual view on the screen.

A.I.M. - Advanced Interactive Map
Nicola Maiellaro Construction Technologies Institute
National Research Council Bari, Italy
Abstract—This paper discusses the ongoing development of a tool to produce - through an authoring system - an interactive map with advanced functions. A first map has been produced in collaboration with the Municipality of Cetinje (Montenegro); a map of the Municipality of Gioia del Colle is still under construction with students of a secondary school. These activities concern the Mu.S.A. (Must See Advisor) Project, a cultural heritage booster aiming at giving visibility to less known sites - as potential tourism destinations - by valuing knowledge from selected communities.
Index Terms—Authoring System, Interactive Map, Capacity Building.
I. INTRODUCTION Keeping in mind the ‘average’ visitor that more and more
frequently searches for information directly on the Web before moving, initiatives could be made more effective using interactive maps published on the Internet. The use of GIS software to serve maps over the Internet is already available with a wide variety of approaches – see, for example, the map of Cyprus (http://geomatic.com.cy/visitcyprus/) and Malta (www.visitmalta.com) at regional level and the map of U.S. Cities as Lake Havasu (http://lakehavasu.micromaps.com) and Oswego (http://oswego.lunarcowimap.com/imap).
It can perform just about any GIS function but it requires very advanced GIS and other technical skills - for most small municipalities and local communities, this approach may not be the best one. Therefore, our Institute developed “Smart Map+”, procedures and software specifically designed to simplify the publication of geo-referenced information generated using a camera equipped with GPS.
It was developed in the framework of the Mu.S.A. (Must See Advisor) Project, a cultural heritage booster aiming at giving visibility to less known sites - as potential tourism destinations - by valuing knowledge from selected communities.
The procedure includes: planning and executing of a survey with photos acquisition; geolocalization of Point of Interest (P.o.I.) using smartphones, maps or metadata available for shots taken by GPS camera; data input and map generation.
The last step is performed through an Authoring System, specifically implemented, running on a web browser [1].
II. THE AUTHORING SYSTEM At present, the Authoring System reads two different files: • A “list” file containing, for each P.o.I., basic
information (longitude and latitude; title; accessibility level; century; age; address; short description; marker name; typology; typology marker name; survey date; filename of extended description; name of the main photo at different resolution and frame; rating).
• A “media” file containing additional information about media available for each P.o.I. (reference P.o.I.; media type as sheet, image, video, 3D; preview image of media; P.o.I. title; media description; media URL; source; source URL; media date of production).
Then, using switchable parameters, it produces a preview map; given the purpose of the system and possible difficulties in finding cartographies, the authoring system uses Google Maps. Finally, it allows to input additional parameters for the project (the map filename and the window title), the header and the map (clustering distance and threshold); when the user has completed the data input, it prompts to produce the interactive map according to the output needed with different contents and functions.
III. MAP FEATURES The Advanced Interactive Map interface has two main
components: a menu (fig.1, on the left) and a sidebar (fig.1, on the right); according to function selected in the menu, and/or action performed on the sidebar, the map sets and shows it’s components, as the time slider (fig. 1, on the left) and the slideshow of main photos of P.o.I. (fig. 1, bottom).
Each P.o.I. has its own marker: it could be the same reported in the sidebar, or a customized one in order to point out a feature (e.g. a qr-code availability). We use those available at http://mapicons.nicolasmollet.com (it contains also our icons), selecting a white boundary to improve the visibility on dark backgrounds.
The sidebar has a dynamic legend, displaying by type the number of P.o.I. available according to search results and filtering. The sidebar enables the user to conduct a text search, thus going beyond the concept of making location the common thread for P.o.I. retrieval [2].

Fig. 1. Advanced Interactive Map and some of its components
The sidebar has a set of colors unambiguous both to colorblind and non-colorblind people (http://jfly.iam.u-tokyo.ac.jp/color); these constraints limit to five the number of different P.o.I. types.
At the first level, the legend has five different colors and picture; if sub-types are available, there are no pictures (like “Hystoric Building): the picture are available only at the second level according to each sub-type. At the third level, a P.o.I. box (image, name, address) is dysplayed.
Clicking on type and sub-type boxes enable/disable the view of related markers in the map.
The menu allows localizing the best site, to switch on/off satellite view and to show/hide functions – at present:
• Slideshow, an animated collection using a set of main photo of each P.o.I., linked to its position.
• Time slider, an interactive bar allowing filtering all the P.o.I. existent at the selected century.
• Folder, a gallery of media previews (linked to object), organized by slideshow (manual/automatic) or by tile.
• Table, a list of all the media (linked to each object) ordered by P.o.I., media source, media type and media content, with search function.
The callout (fig. 1, center) associated to each P.o.I. shows the name, the address, the main photo, a set of function, a short description linked to an extended version (more), age and two icons about rating and accessibility.
The set of function has sheet, image, video and 3D buttons, in order to show the folder filtered by the selected media; a table button is also available, in order to view the list of media belonging to the selected P.o.I.
IV. ONGOING ACTIVITIES The capacity building activity at the secondary school is
highlighting the opportunity to improve the friendliness of the authoring system and to erase the limit of use only landscape images with fixed ratio, due to the wide ratio availability of images and the constraints imposed by tall buildings or reduced street.
Future work includes the shift towards the use of different shapes for marker type according to [3] and the development of more functions in the menu (as print map, user profile) and in the callout (as way to, select, like, share).
