- In GIS, there are primarily two types of overlay operations:12
- Intersect: Produces a map layer that includes only areas where both input layers coincide.
- Union: Generates a map layer covering all areas from both input layers.

- 1. Point-in-area (also known as point in polygon)
- 2. Line-in-area (also known as line in polygon)
- 3. Area-on-area (also known as polygon on polygon)
