Using the Mask button on the Image Analysis window

The Mask button can be used with any raster, mosaic, or image service layer to create a hidden or masked area within the dataset. The masked area can be defined by the following:

The masked area will appear transparent in the temporary layer.

Steps:
  1. To view the Image Analysis window in ArcMap, click Windows on the Main menu and click Image Analysis.
  2. Click a layer in the Image Analysis window.
  3. Optionally, select a polygon feature within a feature class layer or select a polygon graphic.
  4. Click the Mask button Mask.

    The masked output is added as a temporary raster layer to the table of contents. By default, the masked area is the area defined by the display view extents; otherwise, it is clipped to the selected feature or graphic.

    The Mask operation adds the Clip function to the raster layer.
