CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 1 WGISS EO Data Portal Introduction Wyn Cudlip BNSC/QinetiQ [email protected] Presentation to WGISS WGCV Joint Meeting Cordoba, March, 2005 Slide 2 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 2 EO Data Portal Aims o To co-ordinate CEOS-member activities in the area of improving access to both global and local EO datasets. o To encourage the use of OGC standards to support the interoperability of data services. o To prototype OGC-based web-services in order to generate Guidelines & Lessons learnt Documents to assist with the implementation of operational systems. o To maintain a EODP homepage containing links to the OGC-compliant data servers of CEOS members. Slide 3 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 3 History o Original motivation to assist UN in improving access to Landsat Global Mosaic data (1975, 1990, 2000) and to SRTM global 90m- resolution digital elevation data (DEM) o Originally referred to as CLASP n CEOS Landsat and SRTM Project o Renamed to EO Data Portal Task Team to broaden scope and make idea more attractive to CEOS Plenary Slide 4 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 4 The CLASP Concept o CEOS WGISS to assist the UN and FAO in promoting the exploitation of the Landsat and SRTM data by: n Coordinating the deployment of data mirror sites hosted by various Space Agencies around the world. n Working with standards bodies (e.g. the OGC) to accelerate the development of relevant standards and software (particularly OGC WCS). n Encouraging the development of standards-based software tools and associated web-based services. o Phased development over two years, starting with simple map display capability, leading eventually to chained services that can be tailored for specific applications. Slide 5 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 5 EO Data Portal Structure EODP TT CLASP Other initiatives e.g. Digital Asia WGCV Test Sites ICEDS Other datasets Onearth JPL/NASA EODP homepage Other initiatives (TBD) GMU/LAITSWorldWind visualisation Slide 6 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 6 ICEDS web client Slide 7 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 7 Visual data in other clients (e.g. ArcGIS) Slide 8 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 8 View WCS data in customised client o Simple client based on the client/server architecture developed with IDL n Code is easily portable via an IDL virtual machine which is freely available o Allows on-line connection to the o ICEDS WCS server n Signed 16-bit data retrieval n Display 3D perspective views of n SRTM DEM n Vertical exaggeration control n parameter n Possibility to choose desired n area by BBox Slide 9 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 9 EODP Homepage o Expert users need more than simple visualisation client o EODP intends to provide comprehensive list of CEOS- member OGC-compliant servers o Provide links to n Service introductory webpage n Client for viewing data n Server address (for GetCapabilities) o http://wgiss.ceos.org/eodp Slide 10 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 10 Example EODP content o BNSC o ICEDS (SRTM 90m, Landsat5 mosaic(1990) + links to other servers) o Info:http://iceds.ge.ucl.ac.uk/http://iceds.ge.ucl.ac.uk/ o Viewer: http://iceds.ge.ucl.ac.uk:8080/viewer/iceds/index.html http://iceds.ge.ucl.ac.uk:8080/viewer/iceds/index.html o Servers: o http://iceds.ge.ucl.ac.uk/cgi- bin/wms?map=wms.map&SERVICE=WMS&REQUEST= GetCapabilities http://iceds.ge.ucl.ac.uk/cgi- bin/wms?map=wms.map&SERVICE=WMS&REQUEST= GetCapabilities o http://iceds.ge.ucl.ac.uk/cgi- bin/wcs?map=wcs.map&SERVICE=WCS&REQUEST=G etCapabilities http://iceds.ge.ucl.ac.uk/cgi- bin/wcs?map=wcs.map&SERVICE=WCS&REQUEST=G etCapabilities Slide 11 CEOS WGISS/WGCV Meeting Cordoba, March, 2005. 11 Future Plans o Continue CLASP software development and data distribution o Interested Agencies to develop their own Portal and data servers o Provide more information on access to OGC- compliant data servers o Develop links with WGCV n (presentation by Prof. Muller to follow).
