Resource Abstract:
GlobCover is an ESA initiative which began in 2005 in partnership with JRC, EEA, FAO, UNEP, GOFC-GOLD and IGBP. The aim of the project was to develop a service capable of delivering global composites and land cover maps using as input observations from the 300m MERIS sensor on board the ENVISAT satellite mission. ESA makes available the land cover maps, which cover 2 periods: December 2004 - June 2006 and January - December 2009.

Resource Classification Categories:
GlobCover legend categories for croplands follow:
11 Post-flooding or irrigated croplands
14 Rainfed croplands
20 Mosaic Cropland (50-70%) / Vegetation (grassland, shrubland, forest) (20-50%)
30 Mosaic Vegetation (grassland, shrubland, forest) (50-70%) / Cropland (20-50%)
Reprocessing for MODIS-GLAM (250-meter) applications:
The 300-m Globcover 2009 crop mask was resampled to 250-meters for cropland data drilling on MODIS-GLAM. The processing steps follow:

  1. Pixels for category 14 (Rainfed croplands) and category 20 (Mosaic Cropland 50-70%) were set to a binary value of 1.
  2. Above binary data set at 300-meters was resampled to 250-meters spatial resolution.
