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 Sumatra Lat: 5 06 45.70 Long: 95 20 38.38 12 June 2001, L7 29 December 2004, L7 FilledSLC-off
6 Special Requests: Indian Ocean Campaign Planned acquisitions Interesting cloud formations
7 Burn Severity Atlas support 13 July 2006 Night image: 6,7,5 Sawtooth and Millard Fires, CA
8 Mid-Decadal Global Land Survey Landsat 7Landsat 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
13 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 http://ldcm.usgs.gov/documents.php
14 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 http://www.landimaging.gov

16 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.
