  1. GEOGLAM Status Report Brian Killough + SEO TeamSDCG-4 MeetingSeptember 4-6, 2013Pasadena, CA, USA

  2. Recent Accomplishments • Regions and Phasing (UMD and Asia-Rice) • Cropland Maps (UMD) and Cropland Extent (SEO) • Updated Measurement and Product Requirements (UMD/SEO) • Updated Mission List – Optical and SAR (SEO) • Sampling Coverage by RapidEye • Mission Combination Analyses

  3. Phase-1 Regions Phase 1A: Large-Scale Argentina, Australia, Thailand Phase-1A: Asia-Rice Sampling Thailand, Indonesia, Vietnam Phase-1B Regions: 7 new large crop regions 6 new Rice sample regions

  4. Phase-1A Large-scale Croplands New COVE 2-D Output ... Argentina, Australia

  5. Phase-1B Large-scale Croplands

  6. Phase-1A/1B Asia-Rice Sample Regions

  7. Argentina – Cropland Extent

  8. Australia – Cropland Extent

  9. Crop Calendar - Argentina

  10. Crop Calendar - Australia

  11. Measurement Requirements Coarse:MODIS or NPP DailyWall-to-Wall Moderate: Landsat / Sentinal-2Weekly to MonthlyWall-to-Wall Fine: RapidEye Weekly to MonthlySample Sites

  12. Information Products Coarse: Crop ConditionCrop Mask Moderate: Crop TypeCrop Mask/Condition Fine: Crop TypeCrop Condition(sample validation)

  13. Missions and Instruments - Optical

  14. Missions and Instruments - Radar

  15. Argentina Sampling Performed a COVE analysis for RapidEye: One day, Sept 8, 5 satellites (below).All sites require 12 passes or ~4 days 75 sample sites

  16. Asia-Rice Radarsat-2 Summary • WF2 mode • Thailand, Nov 10 example below

  17. Multi-Mission Revisit Performance L7 and L8 = Landsat 7 and Landsat 8S2A and S2B = Sentinel-2A and Sentinel-2B R2 = ResourseSat2 * Results are over Argentina, but variations are small in others areas of the globe (-40 to +40 latitude)

  18. Synergies with GFOI • GFOI = Global Forest Observation Initiative • Forest and agriculture regions within any country are NOT the same. • Wall-to-wall optical coverage is the likely synergy for acquisitions. • GFOI country list includes FCT, REDD+ and UN-REDD = 44 total. GEOGLAM country list includes 21 “producers” and 5+ “at risk” countries = 26+ total. • There are 6 “producer” countries and 1 “at-risk” country that are common between GFOI and GEOGLAM. These include Argentina, Australia, Brazil, Paraguay, Thailand, Vietnam, and Uganda (at-risk).

  19. Next Steps • Sampling scheme for Australia • Monthly cloud probability analyses using UMD data for MODIS and mission combination results. • Landsat Path-Row analyses for Argentina and Australia
