Description
Global grid of multi-cropping zones. Native resolution is 5 arc minute projected in Geographic Coordinate System WGS 1984.
Multi-crop zone classes:
Multicrop classes | |
1 | No cropping |
2 | Single cropping |
3 | Limited double cropping |
4 | Double cropping |
5 | Double cropping with rice |
6 | Double rice cropping |
7 | Triple cropping |
8 | Triple rice cropping |
Processing Procedure
1. In ArcMap 10.0, convert native data to 30 arc second resolution.
2. Reclassify into numerical classes.
3. Use zonal statistics to calculate mean values within each GLU.
Data Coverage
Data is coded by the number of cells covered by the native data (1), data extrapolation (2), and not covered by either (3).
