There is long-standing recognition of the need for global forest change detection at Landsat-class resolutions. We have developed a strategy for producing the following Earth Science Data Records (ESDR) at fine and moderate spatial resolutions and provide the algorithms and services for producing such products:
• Global fine resolution (< 100 m) surface reflectance ESDR for four epochs centered around 1990, 2000, and 2005;
• Fine resolution (< 100 m) forest cover change (FCC) ESDR between the four epochs;
• Fragmentation products derived from the fine resolution FCC products;
• Global 250-m vegetation continuous field (VCF) based FCC ESDR from 2000 to 2005;
• FCC ESDR products aggregated from the fine resolution and the 250 m FCC products to 250 m, 500 m, 1 km, and 0.05 grids for use by carbon, biogeochemical and hydrological modelers;
• Subsets of the above products for protected areas of the world and their buffer zones.
In addition to providing these products at the native resolutions and the above listed modeling resolutions, we will also provide estimates of forest cover change from 1990 to 2005 at country, biome, continental, and global levels.
