INSPIRE – recap

EU-wide SDI perspective on data

Ultimate goal is to unlock spatial data and lay down

foundations of European SDI

INSPIRE is a Framework Directive

• Into force since 15th of May 2007

Detailed technical provisions are laid down in:

Implementing Rules on

Metadata

Spatial Data

Network services

Data and Service sharing (policy)


INSPIRE principles

Data should be collected once

Possible to combine data from different sources

Focus on information relevant for governance

Focus on reusability

GI should be easily discoverable, together with

its metadata

Distributed Service Oriented Architecture (SOA)


Value added of INSPIRE

Building blocks for interoperable SDI in the following context

• Cross-country

• Cross-domain

• Combination of the above

Harmonization and standardization of environmental data across Europe (and beyond)

Legally binding for public administrations with data in scope

Business aspects of INSPIRE

• Rapidly growing geospatial sector

Code lists

4 types of INSPIRE code lists

according to extensibility

a) not extensible – only values included in IRs are allowed

b) narrower extensible – values included in IRs and narrower

values are allowed

c) freely extensible – values included in IRs and any other values

are allowed

d) empty – any values are allowed

For code lists of types (b), (c) and (d), additional values have to be

published in a register

TG-DS may include additional proposed values that will be published in

the INSPIRE code list register

infrastructure and resources (250000+)

Discovery services


INSPIRE Metadata

Distinguish between

• Spatial object metadata

• Dataset-level metadata

Tools available at JRC site

• INSPIRE Metadata editor

• INSPIRE metadata validator


Metadata editor

http://inspire-geoportal.ec.europa.eu/editor/


Discovery services

„discovery services making it possible to search for spatial data sets

and services on the basis of the content of the corresponding

metadata and to display the content of the metadata“

http://inspire-geoportal.ec.europa.eu/discovery/

http://inspire-geoportal.ec.europa.eu/discovery/


Operations (Article 11(1) of Directive 2007/2/EC)

1. Get Discovery Service Metadata: Provides all necessary information about the service and describes

service capabilities

2. Discover Metadata: The Discover Metadata operation allows requesting INSPIRE metadata elements of

resources based on a query statement to be retrieved from the target Discovery Service

3. Publish Metadata: The Publish Metadata operation allows editing INSPIRE metadata elements of

resources in the Discovery Service (push or pull metadata mechanisms). Editing meaning insert,

update and delete

4. Link Discovery Service: The Link Discovery Service function allows the declaration of the availability

of a

Discovery Service for the discovery of resources through the Member State Discovery Service while

maintaining the resource metadata at the owner location


View Services


View services

„view services making it possible, as a minimum, to display, navigate,

zoom in/out, pan, or overlay viewable spatial data sets and to display

legend information and any relevant content of metadata“


View services

INSPIRE View Services allow users and computer programs to view

spatial datasets.


TG for View services

• TG for View services specifies requirements and

recommendations based on the European de jure standard

[ISO 19128] – Web Map Service (WMS) 1.3.0.

• It defines an INSPIRE Profile of [ISO 19128]

• INSPIRE Profile of [ISO 19128] also make use of the OGC™

Styled Layer Descriptor (SLD)


Operations

1. Get View Services Metadata: Get metadata

about a specific view service;

2. Get Map: Returns a map for a specified area;

3. Link View Service: Allows the linking of view

services together.

Naming:


Link View Service

Allows a Public Authority or a Third Party to declare a View Service for

the viewing of its resources through:

• Member State View Service while

• maintaining the viewing capability at the Public Authority or the

Third party location.

sets, to be downloaded and, where practicable, accessed directly“

Transformation

simple transformation - renaming, assign new properties

complex transformation - reclassification, geometry calulation

origin conformant

architectural approaches, an Overview

One-off transformation + external web based services | Atom/WFS/…

One-the-fly transformation | Atom/WFS/…

Hybrid transformation + integrated web based services | Atom/WFS/…

but what happened with changes (update)?

need to maintain,don’t forget

Consider for choosing an

approach (operational process)

will the data set in future

• +/- static,

e.g. geology

• under frequently change,

e.g. land use

• under permanent change

e.g. air quality reporting


One-off transformation + external web based services

positive aspects are:

transformed once for all users

• better performance when delivering the

data

• no transformation during delivery

• Wide choice of software components

negative aspects are:

Requires storage and management of

transformed data

in addition to original data

• high processing effort

• the entire database is transformed

• to be maintained also transformed data

This approach is useful if data are stable


On the fly transformation+ integrated web services

positive aspects are:only the original data has to be

maintainedonly the requested data has to be

transformed

negative aspects are:Performance issues• high processing required before delivery

especially for large volumes of data and complex transformations

• the same data is potentially transformed multiple times

• Caching or pre-processing mechanisms has to be used

This approach is useful if data is continuously or frequently updated

eg. Snowflake/GoLoader/-PublisherWFS, GeoServer (?)


One-off transformation + DB + integrated web based

services

positive aspects are:

Data transformed offline can be

managed in same system as original

data e.g. in the same database management

system, not as GML files

• ‘On-the-fly’ get more performance

because of predefined data structure

negative aspects are:

Data provider still has to store

transformed data

Limited FOSS-GIS solutions (current)

This approach is useful if data is continuously or frequently updated

eg. ArcGIS for INSPIRE
