Analyze Data with Overlays

Use overlays to compare two layers. For example, to find out which parcels contain different soil types, overlay a soil analysis layer on a parcel layer.

Use different types of overlays (for example, intersect, union, identity, or erase) to examine the common or uncommon areas. For a complete list, see Overlaying Two Feature Sources.

The results are stored in a new Display Manager layer, which you can style and save as an SDF file.

Connect to the two data stores to compare

Specify the layers to compare, the type of overlay to perform, and the overlay settings to use. Specify a file to store the results as a separate data store.

Turn off the display of the original layers to examine the overlay results.

Select fill and line styles and transparency settings for the overlay layer.
