Transcript of "Dissemination of the UAE solar resource atlas over the web: preliminary results"

  1. 1. DISSEMINATION OF THE UAE SOLAR RESOURCE ATLAS OVER THE WEB: PRELIMINARY RESULTS Jacinto Estima and Hosni Ghedira Research Center for Renewable Energy Mapping and AssessmentMasdar Institute of Science and Technology, Abu Dhabi, United Arab Emirates 1st regional Geospatial Scientific Summit (GSS), 2012 American University in Dubai, United Arab Emirates 12-13 November 2012
  2. 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)Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 2Hosni Ghedira American University in Dubai
  3. 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 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 resourcesJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 3Hosni Ghedira American University in Dubai
  4. 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 standardsJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 4Hosni Ghedira American University in Dubai
  5. 5. OGC, OPEN STANDARDS AND WMS (1)• The first attempts to develop systems to share information were mostly based on proprietary technologies• Interoperability problems 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 using open specifications can talk the same language which means that they can understand each other and easily exchange informationJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 5Hosni Ghedira American University in Dubai
  6. 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…Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 6Hosni Ghedira American University in Dubai
  7. 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 locationJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 7Hosni Ghedira American University in Dubai
  8. 8. OGC, OPEN STANDARDS AND WMS (4) – WMS GetCapabilities operation exampleRequest:http://localhost:8080/geoserver/wms?request=getcapabilitiesAnswer: <Layer queryable="1"> <Name>masdar:2004_DHI_apr</Name> <Title>2004_DHI_apr</Title> <Abstract/> <KeywordList> <Keyword>GeoTIFF</Keyword> <Keyword>2004_DHI_apr_geo</Keyword> </KeywordList> <CRS>EPSG:4326</CRS> ………Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 8Hosni Ghedira American University in Dubai
  9. 9. DEVELOPMENT OF THE APPLICATION• 3 Components: – Data source (GeoTIFF images) – Geospatial data server (Geoserver – implements WMS, SLD and others) – User (Web Portal + Remote Client)Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 9Hosni Ghedira American University in Dubai
  10. 10. PRELIMINARY RESULTSJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 10Hosni Ghedira American University in Dubai
  11. 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)Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 11Hosni Ghedira American University in Dubai
  12. 12. 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 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 consideredJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 12Hosni Ghedira American University in Dubai
  13. 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.Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 13Hosni Ghedira American University in Dubai
  14. 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:Jacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 14Hosni Ghedira American University in Dubai
  15. 15. 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 Atlas – The Global Atlas will be hosted at Masdar InstituteJacinto Estima 1st regional Geospatial Scientific Summit (GSS), 12-13 November 2012 15Hosni Ghedira American University in Dubai
