  2. MEaSUREs & the LP DAAC

  3. MEaSUREs – U. of AZ Phenology Global EVI2 ESDR

  4. Vegetation Index/Phenology ESDR • PI Dr. KamelDidan, University of Arizona • Multi-platform Vegetation Indices (AVHRR-VGT-MODIS-VIIRS) • Continuous time series (1989 – present) • 2-band Enhanced VI + Phenology Metrics • LP DAAC Role (co-I) • Distribution (including “operational beta” system) • User Services model definition & implementation • Metrics Reporting • Outreach Support

  5. Web-enabled Landsat Data (WELD) ESDR • PI – David Roy, South Dakota State University • For an 8-year period (2005 through 2012) they will generate monthly, 3-month (seasonal) and annual surface reflectance composite mosaics of the conterminous U.S. and Alaska by processing every Landsat 7 ETM+ acquisition. • Cloud screened, cloud and gap filled • Atmospherically and geometrically corrected, normalized for solar and viewing geometry • The mosaics to be updated at the pixel level in near real-time. • MODIS atmospheric characterization will be systematically applied to atmospherically correct the Landsat ETM+ data • The 500m MODIS BRDF/Albedo product will be used for correction of ETM+ solar and viewing geometry and gap-filling

  6. WELD ESDR • GeoTIFF format products are available in user defined regions via a What You See Is What You Get (WYSIWYG) WELD distribution interface at http://weld.cr.usgs.gov • HDF-EOS tiled WELD products are also available via anonymous FTP at ftp://weldftp.cr.usgs.gov/ • The final version of the HDF tiled WELD products (pending favorable review of the ESDRs) will be distributed by the end of the project from the LP DAAC.

  7. Global Forest Cover Change ESDR PI – John Townsende, University of Maryland Assess global forest cover change (FCC) First global scale assessment at Landsat resolutions Develop the capability for routine monitoring Generate FCC ESDR products to support global change studies,nationaland international research programs. Product Distribution: GLCF FTP ESDI (Earth Science Data Interface) Including all deliverables LP-DAAC (planned) Archive Distribution

  8. GFCC Product Distribution GLCF FTP ESDI (Earth Science Data Interface) Including all deliverables LP-DAAC Archive Distribution

  9. ESDR Integration – LP DAAC • Assumed timeline (all ESDRs?): • FY12 – ingest, ECHO integration • FY13 – continued ingest, operational distribution • FY14 – implement user support model • For Didan & Roy - prototype distribution place by 2012 • LPDAAC to distribute WELD tiles for Roy (seamless distribution from Landsat/LDCM)

  10. Questions • When (how many months into the MEaSUREs project) were first contacts with Data Centers made – was it good enough? • VIP – LP DAAC is co-I (since inception) • WELD – USGS/EROS Landsat is co-I (co-located with LP DAAC) – presentation to UWG in August, 2008. • GFCC – Contact in January, 2010, participated in April 2010 review.

  11. Questions • What products currently handled by Data Center are similar to products from MEaSUREs? • VIP – similar MODIS products • WELD – Landsat developed around MODIS algorithms (tiling, surface reflectance, composting) • GFCC – No specific analog, although MODIS includes thematic and change products.

  12. Questions • What products currently handled by Data Center are likely to be used along with those from MEaSUREs? • VIP– similar MODIS products (VI & phenology) • WELD – All MODIS land products, + ASTER (also NSIDC MODIS snow products) • GFCC – All MODIS land products, + ASTER (also Landsat Standard products through WIST)

  13. Questions • What is the implication on interoperability from a user’s point of view? • VIP– “one-stop shop” • WELD – Blending/fusing with MODIS & ASTER products, links to atmosphere & snow products (within ESDIS framework) – interoperability issues with Landsat archive? • GFCC – Interoperability issues with Landsat archive?

  14. Questions • Have data formats been chosen for MEaSUREs products? What approach was (or is being) used to make the selection? • VIP– HDF-EOS production, GeoTIFF selectable for distribution services. (MODIS history) • WELD – HDF-EOS production, GeoTIFF selectable for distribution services. (MODIS history) • GFCC – Production of both HDF-EOS and GeoTIFF products. (MODIS history)

  15. Questions • What metadata standards have been agreed upon? How are search, access and utilization of data being facilitated by metadata? • Based on the selected HDF-EOS data format, metadata generation is planned to follow ECS standards specifically to facilitate standard ESDIS and ESIP Federated search vehicles, as well as to facilitate distribution services interoperability.

  16. Questions • Provenance? TBD • Agreements? • VIP – yes • WELD – yes, with Landsat/LDCM projects (not LP DAAC) • GFCC – not yet.
