Land use
The land use data gives information on the cropland fractions of a certain location. meteoblue offers the following datasets:

| Description |
The GFSAD30 is a NASA funded project to provide high resolution global cropland data and their water use that contributes towards global food security in the twenty-first century. The GFSAD30 products are derived through multi-sensor remote sensing data (e.g., Landsat, MODIS, AVHRR). meteoblue provides the original cropland mask at 30 m resolution, as well as aggregated versions at coarser resolutions of 250 m and 1 km. The aggregated versions give the spatial fraction of cropland within a 250 m by 250 m or 1 km by 1 km box, respectively. Furthermore a global land-water mask is available at 30 m, 250 m and 1 km resolution, indicating the fraction of the grid box, which is covered with land. |
