Global grid of land suitability for agriculture based on combined slope constraints. Native resolution is 5 arc minute projected in Geographic Coordinate System WGS 1984.
Slope suitability classes:
|3||Very Few Constraints|
|4||Partly with Constraints|
|5||Some Severe Constraints|
|6||Frequent Severe Constraints|
|7||Very Frequent Severe Constraints|
|8||Unsuitable for Agriculture|
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 is coded by the number of cells covered by the native data (1), data extrapolation (2), and not covered by either (3).
