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
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

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