  1. Agency Report, WGISS #22 September 15, 2006 Lyndon R. Oleson U.S. Geological Survey Center for Earth Observations and Science (EROS) Sioux Falls, SD

  2. Status of Landsat

  3. Landsat International Ground Station Network

  4. Current status • Landsat 5 • Fixed array operations being implemented, reducing power availability • International acquisitions continuing to be supported • Attempting to acquire as much as possible • Landsat 7 • Scan Line Corrector (SLC) remains off • Gap-filled data increasingly popular • Geometric accuracy within 1 pixel (~15m)

  5. Segment-based Gap Fill Product SLC-off Filled 12 June 2001, L7 29 December 2004, L7 Sumatra Lat: 5 06 45.70 Long: 95 20 38.38

  6. Special Requests: Indian Ocean Campaign Planned acquisitions Interesting cloud formations

  7. Burn Severity Atlas support Sawtooth and Millard Fires, CA 13 July 2006 Night image: 6,7,5

  8. Mid-Decadal Global Land Survey Landsat 7 Landsat 5

  9. Accessibility • Earth Explorer http://earthexplorer.usgs.gov • Global Visualization Viewer http://glovis.usgs.gov • Web Mapping Services http://gisdata.usgs.net

  10. “Web-enabled” Landsat data • Direct web download plans • US only – includes Alaska and Hawaii • L7 ETM+ SLC-off only • Near real-time for newly acquired data • Archive: 2003 to present • Data specs: < 10% cloud cover, 9 quality • Release: February 2007, pending policy updates • Serves as pilot for possibly similar Landsat 8 product access

  11. “Real-time” Acquisition Viewing • USGS has been beta testing an acquisition viewing capability • Recently, the Image Acquisition Viewer 1.0 (Kiosk mode) has been released to selected locations • Soon to be released to public via the internet

  12. Future of Landsat • The Administration has directed NASA and the USGS to team up on development, launch, and operation of a free-flyer “Landsat Data Continuity Mission (LDCM)” • NASA will procure an on-orbit data acquisition capability • USGS to operate and ingest, archive, process, and distribute Landsat-continuity data products. • Visit the LDCM Documents page at http://ldcm.usgs.gov/documents.php

  13. Future of Land Imaging • The White House has initiated a year-long study called The Future of Land Imaging • To explore options for United States operational use of satellites to better serve society. • The USGS serves on the leadership team of this Federal interagency working group. • For more information visit http://www.landimaging.gov

  14. Other Product News • Free Orthorectified Landsat data is now available for download from the Global Visualization Viewer (GloVis) at http://glovis.usgs.gov and Earth Explorer at http://earthexplorer.usgs.gov • Spaceborne Imaging Radar-C (SIR-C) previously-Processed Precision Data now available for downloading at no charge through Earth Explorer at http://earthexplorer.usgs.gov • Advanced Very High Resolution Radiometer Sensor (AVHRR) 7 and 14 Day Greenness Composite Maps now available for download at no charge from the Global Visualization Viewer (GloVis) at http://glovis.usgs.gov and Earth Explorer at http://earthexplorer.usgs.gov

  15. Grid Data Node Experiments • Recently hosted a visit by representatives of the Geophysical Network (GEON) grid user community to explore possibilities for collaboration • GEON is an NSF-funded grid network hosted and technically supported by SDSC • We are exploring scenarios for experimenting with different access methods with different data products such as: • USGS LiDAR point cloud data • National Elevation Dataset (NED) DEMs • Landsat data • Our goal to learn how to implement operational data node relationships with various grid communities. • Will share initial lessons-learned at WGISS #23.
