Description: MODIS-IGBP has two classes describing agricultural areas. These classes have been isolated in this crop mask file (along with class 0, which equals oceans and in-land water bodies). All other classes were combined into class 1 in this file. Croplands (class 12) now equals 2. Croplands/Natural vegetation mosaic (class 14) now equals 3. Making all the classes transparent (No color), except for class 1 (have it represent land) masks away all non-croplands when displaying CADRE or MODIS/SPOT-Veg data.
