Crop a Global Raster to the Extent of Planning Units

crop_global_raster.Rd

This function crops a large global raster to the spatial extent of a planning units raster (pus). It reprojects the pus extent to the coordinate reference system of the input global raster to ensure accurate cropping. This is useful for pre-processing global inputs before using functions like make_normalised_raster() to reduce processing time.

Utilisation

crop_global_raster(raster_in, pus, threads = TRUE)

Arguments

raster_in

SpatRaster. A large input raster (e.g., global dataset).

pus

SpatRaster. Planning units raster used to define the target extent.

threads

Optional method to use multi-core processing - to speed on some terra functions (default: TRUE).

Valeur de retour

A cropped SpatRaster with the same CRS as raster_in and extent matching the reprojected pus.

Exemples

if (FALSE) { # \dontrun{
cropped <- crop_global_raster(global_raster, pus) |>
  elsar::make_normalised_raster(pus = pus, iso3 = "KEN")
} # }
