Erase Raster with Polygons
Open Table of Contents ToolBox Implementation
Erases a raster dataset with the polygons of the input polygon feature class.

Inputs:

  • A polygon feature class
  • A raster dataset representing.

Outputs:

  • A raster with NoData values for the cells overlapping the erase polygons.

Example:
Input raster and erase polygons
Result raster

Notes:

  • Initially the name of the output raster defines the raster format
    • no extension specified - ESRI binary GRID
    • .img extension (for example raster1.img) - ERDAS IMAGINE image.
    • .tif extension (for example raster1.tif - Tagged Image File Format (TIFF) image.
  • The initial output raster format can be changed by selecting the desired output in the dialog.
  • Currently only file based rasters are supported. Rasters cannot be stored in a GeoDatabase. After you get the desired result, you can export the raster to a GeoDatabase using the standard ArcGIS tools.
  • The input feature class and raster must have the same projected coordinate system.

Parameters

Expression Explanation
<Input Raster> A Raster dataset or Raster layer
<Erase Polygons> A Polygon layer or feature class
<Out Raster> A String - the full name of the output raster (A raster with the same full name should not exist). The output raster type depends on the extension of the output file(see Notes above)
