Resource Abstract:
An inventory of major land cover/land use categories has been compiled using an iterative calculation procedure to estimate land cover class weights, consistent with aggregate FAO land statistics and spatial land cover patterns obtained from remotely sensed data and geographic datasets, including GLC2000 land cover database, an IFPRI global land cover categorization data set, FAO's Global Forest Resources Assessment, the Global Map of Irrigated Areas of FAO/University of Frankfurt, and a population density inventory developed by FAO-SDRN. The results provide shares of major land use and land cover categories within individual 5 arc-minute grid-cells. These categories are: (i) Rain-fed cultivated land; (ii) irrigated cultivated land; (iii) forest land; (iv) grassland and woodland; (v) barren and sparsely vegetated land; (vi) urban and other land required for housing and infrastructure, and (vii) inland water bodies.
Resource Classification Categories:
Rain-fed cultivated land (percent)
Irrigated cultivated land (percent)
Reprocessing for MODIS-GLAM (250-meter) applications:
The rain-fed cultivated file was resampled to a raster image with 250-meters spatial resolution for cropland data drilling on MODIS-GLAM. The processing steps follow:
