Global Cropland Intensity

- Description:
- This dataset is derived from a combination of satellite imagery and national level census data using an algorithm developed by Navin Ramankutty of the University of Wisconsin. Although this image is for 1992, the dataset was originally compiled as part of a historical croplands dataset that runs from 1700 to 1990.
The grid contains fractional cropcover data, meaning the number given for each gridcell is the fraction of that gridcell's surface that is covered by crops. Thus a value of 0.7 means that 70% of the cell is being used for agricultural purposes.
