1 CEOS Working Group on Information Systems and Services - 1 Core Site WGISS Test Facility WGCV & WGISS Efforts John Faundeen & Stu Doescher, USGS WGISS-15 May 2003 Toulouse, France

2 CEOS Working Group on Information Systems and Services - 2 Background o September 2001 proposal via WGCV (Yves-Louis Desnos) o WGISS-13 Discussions (Peter Churchill) o Spring of 2002 – USGS agrees to sponsor a WTF o The WTF plan discussed at … n WGCV Ottawa Meeting (May 2002) n WGISS Frascati Subgroup (May 2002) n WGISS Alexandria Subgroup (Sept. 2002) o The WGCV/WGISS WTF plan approved 15 October 2002 o edcsgs16.cr.usgs.gov/wgiss/ n username = calval99 password = wgiss03

3 CEOS Working Group on Information Systems and Services - 3 Objectives · * Establish linkages between site data archives to facilitate improved product access and knowledge assessments of the long-term stability and interoperability to address the challenges of the Terrestrial Carbon Observation (TCO) theme. * Ramp-up validation efforts, leveraging off of the infrastructure and protocols developed through existing site activities, · * Address science questions suitable for combined field and multi-resolution data. · * Enable ready collaboration between validation investigators and existing science networks and programs. · * Facilitate validation activities directed at better product knowledge and assessment of the products stability and interoperability.

4 CEOS Working Group on Information Systems and Services - 4 Goals: Phase I o Simple, Web-Based Interface Over CEOS Core Sites o Allow Users to Specify Conversion Parameters o Provide Access to EO and in-situ Data o Begin With MODIS & Landsat o Allow Reprojecting o Allow Reformatting into GeoTIFF

5 CEOS Working Group on Information Systems and Services - 5 Goals Phase II · Incorporate GTOS Terrestrial Ecosystem Monitoring Sites · Add CEOP/NASDA, CSIRO, GT-net, ILTERS as Phase II efforts · Enable synergy within and between Satellite/Sensor science teams for data collection and subsequent research · Provide science community with immediate, easily accessible data from CEOS member sensors · Provide a focus for ongoing satellite, aircraft, and ground data collection for validation of CEOS member satellite/sensor products · Provide scientists with sets of readily accessible in-situ and CEOS member instrument data for algorithm validation and improvement · Build on infrastructure of existing scientific networks and validation sites · Realize international cost-sharing opportunities
