Global Land Cover Datasets
Cultivation Intensity
This page provides access to and describes the GISS dataset "Global Distribution of Cultivation Intensity at 1°×1° Resolution", which distinguishes five levels of cultivation. In combination with the Vegetation dataset, it may be used to calculate land cover.

Explanation of Arrays
The contents of INFO1, INFO2, and INFO3 are:
CULTIVATION INTENSITIES DIMENSION = 360 X 180 SCALE = 1 OCEAN = -9999 UNDEF = 99999 MIN = 1 MAX = 5 NUMREC = 6483 (NUMBER OF RECORDS IN DATA FILE)
The possible values of the elements in IARRAY are:
- 0% cultivated, 100% natural vegetation
- 20% cultivated, 80% natural vegetation
- 50% cultivated, 50% natural vegetation
- 75% cultivated, 25% natural vegetation
- 100% cultivated, 0% natural vegetation
