ESA Web Mapping ActivitiesCEOS-WGISSESRIN 7-10-May-2002Christophe 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
Additionof 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
ASAR AATSR MERIS ENVISAT products Geotiff ENVISAT products Geo-coding engine(in house dev.) Web Map Server
Improvement of Client Application • Improved layer selection (done) • Automatic parsing of capability files • Creation of User Profiles
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.
Collaboration with DLRAtmospheric products 1/2 • Existing NRT server for : • Ozone • NO2 ( Biomass burning …) • Cloud cover • Global Data Sets
Ocean Testing Facility • International collaboration CEOS + Science Users • Duration : ~ 3 years • Share Oceanographic Data • Use of OpenGIS components • New development required Animation, Processing …
