window {terra} | R Documentation |
Set a window
Description
Assign a window (area of interest) to a SpatRaster with a SpatExtent
, or set it to NULL
to remove the window. This is similar to crop
without actually creating a new dataset.
The window is intersect with the extent of the SpatRaster. It is envisioned that in a future version, the window may also go outside these boundaries.
