What is raster overlay?

Raster overlay involves two or more different sets of data that derive from a common grid. The separate sets of data are usually given numerical values. These values then are mathematically merged together to create a new set of values for a single output layer.

What is raster clipping?

This tool allows you to extract a portion of a raster dataset based on a template extent. The clip output includes any pixels that intersect the template extent. To extract a portion of a feature dataset, use the Clip tool in the Analysis toolbox.

Where is the merge tool in ArcMap?

Data Management Toolbox
