Cause

Below are several causes associated with this issue:

    • The raster dataset is not symbolized with two unique classes.

    • The pixel type of the raster dataset is not an 8-bit, unsigned integer.

    • The raster dataset is not in a supported format. The ArcScan Raster Cleanup commands only support TIFF, IMG, or GRID formats.

  

Note:
ArcScan must be enabled in the ArcMap Extensions window, and an edit session must be started prior to using the toolbar. For more information, refer to the following documentation, Problem: ArcScan toolbar is disabled.

Solution or Workaround

Depending on the cause, use one or more of the options listed below to resolve the issue.

  • Symbolize the raster layer to be displayed with two unique classes. To do this in ArcMap, refer to the following documentation, ArcGIS for Desktop Help: Symbolizing a raster for use with ArcScan.
  • Use the Copy Raster tool to convert the raster to an 8-bit, unsigned integer raster and also save the output as either TIFF, IMG or GRID formats since ArcScan Raster Cleanup supports only these formats.
