To illustrate this, we will crop the Canopy Height Model (CHM) to only include the area of interest (AOI). The spatial object as the cropping boundary. Spatial object that will be used to crop the raster.
To do this, we need to specify the raster to be cropped and the We can use the crop() function to crop a raster to the extent of another That the raster layer matches the extent of the desired vector layers. Cropping a raster can also be useful when creating pretty maps so Raster to the extent of our study area to reduce file sizes as we process Sometimes we have a raster file that is much larger than our
Spatial extent of a shapefile or R spatial object represents the geographic
We often work with spatial layers that have different spatial extents. Within a set of polygons, or in a buffer (surrounding) region around a set of
