How do you clip a raster in R?

We can use the crop() function to crop a raster to the extent of another spatial object. To do this, we need to specify the raster to be cropped and the spatial object that will be used to crop the raster. R will use the extent of the spatial object as the cropping boundary.

Can you clip a raster to a polygon?

Use the Clip button on the Image Analysis window The Clip button on the Image Analysis window provides the functionality to clip any raster including a grid using a selected polygon feature within a feature class layer. To save the layer file, export the layer to a new raster dataset.

Can I clip raster data?

An existing raster or vector layer can be used as the clip extent. If you are using a feature class as the output extent, you have the option to clip the raster by the minimum bounding rectangle of the feature class or by the polygon geometry of the features.

Is a shapefile a raster?

Any feature class (geodatabase, shapefile, or coverage) containing polygon features can be converted to a raster dataset. The input field type determines the type of output raster. If the field is integer, the output raster will be integer; if it is floating point, the output will be floating point.
