In some cases, users want to clip out the portions of a raster that fall inside a dataset containing polygon features, and keep only the areas around the polygons.
The instructions provided describe how to clip or extract a raster outside polygon boundaries.
Note: The Extract by Polygon tool requires a Spatial Analyst license.
The Extract by Polygon tool has an extraction area parameter with an outside option which allows cells outside the input polygon to be selected and written to the output raster. All cells inside the polygon receive NoData values on the output raster. However, this tool does not allow the use of an existing polygon feature class for the input polygon. This tool requires the vertices to be entered manually, and is therefore not suitable for erasing more complex geometries.
For more information on the Extract by Polygon tool, refer to the following ArcGIS Web Help page: Extract by Polygon.
Note: The Erase tool requires an ArcGIS Desktop Advanced license and the Extract by Mask tool requires a Spatial Analyst license.
Note: In some cases, the extracted raster does not display properly because of the Stretch function applied to the raster. If this occurs, open the Layer Properties dialog box of the extracted raster > Symbology tab. In the RGB Composite renderer, change the Statistics drop-down list to From The Current Display Extent.
