- 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

- 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

- 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

- 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 othersJacinto Estima 1st regional Geospatial

- 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

- 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

- 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

- 14. CONCLUSIONS AND FUTURE WORK (3) The Center is also involved
in the Development of the Global Atlas for Wind and Solar resources
