DEFINITION

What is a layer?

A map layer is a GIS database containing groups of point, line, or area (polygon) features representing a particular class or type of real-world entities such as customers, streets, or postal codes. Layers can also be of raster images such as those taken by satellites. A layer contains both the visual representation of each feature and a link from the feature to its database attributes. Maps in a Geographic Information System are made by combining multiple layers.
