1 DISSEMINATION OF THE UAE SOLAR RESOURCE ATLAS OVER THE WEB: PRELIMINARY RESULTS and Research Center for Renewable Energy Mapping and Assessment Masdar Institute of Science and Technology, Abu Dhabi, United Arab Emirates 1st regional Geospatial Scientific Summit (GSS), 2012 American University it in Dubai, United darab bemirates November 2012

2 CONTENTS Introduction Open Geospatial Consortium, open standards and Web Map Service Development of the application Preliminary results Conclusions and future work (Global Atlas Initiative) 2

3 INTRODUCTION (1) The Research Center for Renewable Energy Mapping and Assessment at Masdar Institute was mandated by the UAE Government to develop the UAE solarand and wind atlases It is part of the UAE commitment to support the International Renewable Energy Agency (IRENA) in its advancement of a publiclyaccessible atlas of solar and wind resources 3

4 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 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 4

5 OGC, OPEN STANDARDS AND WMS (1) The first attempts to develop systems to share information were mostly based on proprietary technologies Interoperability yproblems arise: 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 eopedusing gopen specifications cat s can talk the esame language which means that they can understand each other and easily exchange information 5

6 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 interface standards, called specifications Several standards developed: Web Map Service (WMS)* Web Feature Service (WFS) Web Coverage Service (WCS) Web Processing Service (WPS) Sensor Observation Service (SOS) Styled Layer Descriptor (SLD)* Among many others 6

7 OGC, OPEN STANDARDS AND WMS (3) Web Map Service (WMS) One of the most famous OGC specifications Based 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.) Implements 3 Operations: GetCapabilities (mandatory) to know what the server has to offer GetMap (mandatory) to get the map image GetFeatureInfo (optional) to get more information about a particular location 7

8 OGC, OPEN STANDARDS AND WMS (4) WMS GetCapabilities operation example Request: Answer: <Layer queryable="1"> <Name>masdar:2004_DHI_apr</Name> <Title>2004_DHI_apr</Title> </Titl > <Abstract/> <KeywordList> <Keyword>GeoTIFF</Keyword> y <Keyword>2004_DHI_apr_geo</Keyword> </KeywordList> <CRS>EPSG:4326</CRS> 8

9 3 Components: DEVELOPMENT OF THE APPLICATION Data source (GeoTIFF images) Geospatial data server (Geoserver implements WMS, SLD and others) User (Web Portal + Remote Client) 9

10 PRELIMINARY RESULTS 10

11 PRELIMINARY RESULTS AVAILABLE DATA Yearly and monthly solar maps Years: 2004 trough 2012 (some not complete) Components: Diffuse Horizontal Irradiation (DHI) Direct Normal Irradiation (DNI) Global Horizontal Irradiation (GHI) 11

12 Conclusions: CONCLUSIONS AND FUTURE WORK (1) Tool very Important for the region Provides a goodway for users and stakeholders to have a better picture of the available solar resources in the country Technology independent and based on open standards 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

13 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 information A Technology Simulator is under development (technology layer) Add other interesting datasets like the grid network, land occupation, RE Policies, etc. 13

14 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: 14

15 Global Atlas: CONCLUSIONS AND FUTURE WORK (3) First version will be launched in January 2013 UAE solar and wind maps will be included in the Global Atlas The Global Atlas will be hosted at Masdar Institute 15
