Global Land Survey Update Jeffrey Masek, NASA GSFC Garik Gutman, NASA HQ John Dwyer, USGS EROS GLS 2005 Status GLS2005 now “essentially complete” about 140 images still missing from Indonesia (Thailand IC) and Brazil Action: replace these with “best of” US archive Product quality, accuracy reports? GLS2005 EO-1 ALI data available through GLOVIS by end of July Bulk Distribution of GLS2005 through UMD Global Land Cover Facility GLS 2010 Activities Campaign Stations for 2009 (+2008) Combined Ground Station Network Landsat-5 Power Issues and GLS High-latitude campaign stations represent a drain on limited L5 power Acquisition schedules revised on June 18: Full Greenland coverage through June 24; reduce to every other path through July 10 Through July 15, reduce KIS/Russia stations, place priority on Australia acquisitions After July 15, place priority on KIS/Russia acquisitions Discontinue L5 coverage of non-continental polar land masses (e.g. small Arctic islands). International Participation CEOS LSI Constellation invited international operators to provide Landsat-like data for GLS2010 and/or Regional Dataset Initiative (November 2008) Positive responses from INPE, CONAE, JAXA, GISTDA CNES interested but no control over SPOT archive No response from ISRO Do we need a higher level bilateral arrangement? Some limited international data will be part of GLS2010, hosted through CEOS WGISS web portal Next Steps Ingest 2009 Campaign Station data at EROS Continue IC/Campaign acquisitions for 2009 Sort metadata, obtain IC selections, process during 2010-2011 Continue to push for greater international contributions …Questions? Topic 2: GLS “1995” Lessons Needed to assemble cloud free, “GLS” like collection of imagery for North America, 1994-96 … Grab all Landsat-5 metadata browse for the region; Use LASSI to select optimal data set Submit bulk processing request But… it’s not so easy Grab Landsat metadata No mechanism exists for downloading Land
