1. ESA Web Mapping Activities CEOS-WGISS ESRIN 7-10-May-2002 Christophe Caspar – Giuseppe Tandurella

2. Presentation Plan Recent development –New available layers –Improved web client Future activities (short / mid-term) –Distribution of MODIS level 1b using WMS & WCS –NRT distribution of O3, NO2 and cloud data (ERS2/GOME data collaboration with DLR) –Ocean Test Facility –Access to MUIS catalogue via WMS interface

3. New Layers …

4. Addition of New Layers GOFC specific layers DMSP, AVHRR hot spots SAR, LANDSAT Frames MODIS 5 and 1 KM, DMSP 5KM BURN Scars Database year 2000 ; ~ 1.5 million points

5. MODIS 1KM (3 Gbytes)

6. ENVISAT products ASAR AATSRMERIS ENVISAT productsGeo-coding engine (in house dev.) Web Map Server Geotiff

7. AATSR 1km resolution – 500 km swath width

8. MERIS 300m or 1.2 km – 1120km swath

9. ASAR 30m/100km swath

10. Improvement on Web Client

11. Improvement of Client Application Improved layer selection (done) Automatic parsing of capability files Creation of User Profiles

12. Short / mid-term plans

13. Access to MUIS BDS ESA Missions: ERS 1& 2 (SAR Image, wave, microwave sounder, windscaterrometer, ATSR) ENVISAT soon. Third Party Missions: JERS SAR, Landsat TM, Landsat MSS, NOAA AVHRR, Nimbus-7 CZCS, IRS-P3 MOS, SeaStar SeaWiFS, MODIS Number of entries: 7 000 000 Number of browses: 200 000 passes Objective : Develop a WMS interface on top of the browse data server to make all scenes available as GIS layers Problem : Need to deal with satellite data in native projection. Need to re-project on the fly.

14. Collaboration with DLR Atmospheric products 1/2 Existing NRT server for : Ozone NO2 ( Biomass burning …) Cloud cover Global Data Sets

15. Collaboration with DLR Atmospheric products 2/2

16. Ocean Testing Facility International collaboration CEOS + Science Users Duration : ~ 3 years Share Oceanographic Data Use of OpenGIS components New development required Animation, Processing …

17. Server A : General GIS data Server B : 5 years Oil Slick Data Server C : Daily SST Static layer CombinationSST time series with additional static GIS layers Metadata for a particular Oil Slick New Phase 2 Data Servers Data Repository Dataset discovery New data representations Science data Images Mixed Capacity for specialized processing at user’s premises downloading raw scientific data Processing Servers -, correlation … e.g. difference between two SST layers. The derived data set appear As new layer that can be further combined.

18. NRT Distribution of MODIS level 1b User MODIS Lvl 1b WMS Visual discovery of available scene 1 00010011 WCS Binary data possibly subset only 2
