A layer with the same name as another layer is not used in an analysis

Last Published: April 25, 2020


If there is more than one layer in the table of contents (TOC) with the same name, Spatial Analyst will use the first layer added to ArcMap to perform an analysis, regardless of the layer you select as input to a function.


ArcGIS 8.1 does not recognize the difference between different layers that have the same name.

Solution or Workaround

Make sure each layer in the TOC has a unique name.
