  1. Core Site WGISS Test Facility WGCV & WGISS Efforts John Faundeen & Stu Doescher, USGS WGISS-15 May 2003 Toulouse, France

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

  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. Goals: Phase I • Simple, Web-Based Interface Over CEOS Core Sites • Allow Users to Specify Conversion Parameters • Provide Access to EO and in-situ Data • Begin With MODIS & Landsat • Allow Reprojecting • Allow Reformatting into GeoTIFF

  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
