INTRODUCTION (1)• The Research Center for Renewable Energy Mapping and

Assessment at Masdar Institute was mandated by the UAE Government to develop the UAE solar and wind atlasesGovernment to develop the UAE solar and wind atlases

• It is part of the UAE commitment to support the International Renewable Energy Agency (IRENA) in its advancement of a publicly‐accessible atlas of solar and wind resources



3

INTRODUCTION (2)• The resultant atlases should be disseminated to end‐users and

stakeholders and included on the future Global Atlas platform

• Dissemination should take advantage of the World Wide Web• Dissemination should take advantage of the World Wide Web– Allows data sharing between different users at different locations

• Ongoing project on the development of an application to make the produced solar and wind maps available to end users and stakeholders:– technology independent and based on open standards– technology independent and based on open standards

OGC, OPEN STANDARDS AND WMS (1)• The first attempts to develop systems to share information were

mostly based on proprietary technologies• Interoperability problems arise:p y p

– “Interoperability refers in general to the ability of various autonomous systems to bring together parts and to operate in collaboration. In most cases this means the exchange of meaningful information” (Vckovaki, 1998)

• Use of clear standards or specifications in order to avoid issues related with interoperability– Applications developed using open specifications can talk the same language pp cat o s de e oped us g ope spec cat o s ca ta t e sa e a guage

which means that they can understand each other and easily exchange information

OGC, OPEN STANDARDS AND WMS (2)• Open Geospatial Consortium (OGC)

– Created in 1994, is an international consortium of 475 companies, government agencies and universities that develops publicly available g g p p yinterface standards, called specifications

– Several standards developed:• WebMap Service (WMS)*Web Map Service (WMS)

• Web Feature Service (WFS)

• Web Coverage Service (WCS)

• Web Processing Service (WPS)Web Processing Service (WPS)

• Sensor Observation Service (SOS)

• Styled Layer Descriptor (SLD)*

• Among many othersAmong many others…

OGC, OPEN STANDARDS AND WMS (3)• Web Map Service (WMS)

– One of the most famous OGC specifications

– Based on XML languageBased on XML language

– Defines the rules to request some geographic layers of an area of interest, and obtains, as result, one or more geo‐registered map images (returned as JPEG PNG etc )JPEG, PNG, etc.)

– Implements 3 Operations:– GetCapabilities (mandatory) – to know what the server has to offer

GetMap (mandatory) to get the map image– GetMap (mandatory) – to get the map image

– GetFeatureInfo (optional) – to get more information about a particular location

DEVELOPMENT OF THE APPLICATION• 3 Components:

– Data source (GeoTIFF images)

– Geospatial data server (Geoserver – implements WMS SLD and others)Geospatial data server (Geoserver implements WMS, SLD and others)

– User (Web Portal + Remote Client)

PRELIMINARY RESULTS

PRELIMINARY RESULTS – AVAILABLE DATA• Yearly and monthly solar maps

– Years:• 2004 trough 2012 (some not complete)2004 trough 2012 (some not complete)

– Components:• Diffuse Horizontal Irradiation (DHI)

• Direct Normal Irradiation (DNI)• Direct Normal Irradiation (DNI)

• Global Horizontal Irradiation (GHI)



11

CONCLUSIONS AND FUTURE WORK (1)• Conclusions:

– Tool very Important for the region

– Provides a good way for users and stakeholders to have a better picture ofProvides a good way for users and stakeholders to have a better picture of the available solar resources in the country

– Technology independent and based on open standards

F t k• Future work:– Move from individual GeoTIFF images to a geospatial database improving

data management and maintenance

– The dissemination of the data itself for certain types of users need to be considered



12

CONCLUSIONS AND FUTURE WORK (2)• Need of authentication mechanism:

– Track the portal usage and get feedbacks from end‐users

– Different profiles of users accessing different types of informationDifferent profiles of users accessing different types of information

• A Technology Simulator is under development (technology layer)

• Add other interesting datasets like the grid network, land occupation, RE Policies, etc.



13

CONCLUSIONS AND FUTURE WORK (3)• The Center is also involved in the Development of the Global Atlas

for Wind and Solar resources for IRENA– Partners in the Global Atlas developer’s team:Partners in the Global Atlas developer s team:



14

CONCLUSIONS AND FUTURE WORK (3)• Global Atlas:

– First version will be launched in January 2013

– UAE solar and wind maps will be included in the Global AtlasUAE solar and wind maps will be included in the Global Atlas

– The Global Atlas will be hosted at Masdar Institute
