ESA Web Mapping Activities
CEOS-WGISSESRIN 7-10-May-2002
Christophe Caspar – Giuseppe Tandurella
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
New Layers …
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
MODIS 1KM(3 Gbytes)
ENVISAT products
ASAR
AATSR
MERIS
ENVISAT products Geo-coding engine(in house dev.) Web Map Server
Geotiff
AATSR 1km resolution – 500 km swath width
MERIS300m or 1.2 km – 1120km swath
ASAR 30m/100km swath
Improvement on Web Client
Improvement of Client Application
• Improved layer selection (done)• Automatic parsing of capability files• Creation of User Profiles
Short / mid-term plans
Access to MUIS BDSESA 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 000Number 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.

Collaboration with DLRAtmospheric products 2/2
Ocean Testing Facility
• International collaboration CEOS + Science Users• Duration : ~ 3 years• Share Oceanographic Data • Use of OpenGIS components• New development required Animation, Processing …
