Extend Raster
The Extend Raster tool creates a new raster from an existing raster and a coverage with a polygon. The polygons in the coverage extend the active region of the input raster, with the elevation values of the polygons being used to assign elevation values on the raster. Elevation values from the polygon’s nodes and vertices will be used to assign elevation values to the raster on the edges of the polygon. Any gaps or spaces in between the input raster and the polygons in the coverage will be filled in by interpolation. NODATA values inside of the polygon will also be filled in by interpolation.
Input Parameters
- Input raster – The raster for which the active boundary polygon will be created.
- Coverage with polygon – A coverage with a polygon that the input raster will be extended to. The polygon should have elevation values that will be assigned to the output raster.
Output Parameters
- Output raster – The new raster created from the input raster and polygons..
