crop_GHSLdata {flexurba} | R Documentation |
Crop GHSL data to the provided extent
Description
The grid cell classification of the Degree of Urbanisation requires three different inputs: a built-up area grid, a population grid, and a land grid. The grids can be downloaded from the GHSL website with download_GHSLdata()
.
This function reads the downloaded grids from the global_directory
and crops them to the provided extent. The newly cropped grids will be saved in the output_directory
, together with their respective metadata (in JSON format).
