Explanation of Solution

Layers are geographic data of different types which are gathered and encrusted together in a Geographical Information System (GIS). Layers can be recorded digitally and are inculcated in a GIS database.

Each layer could be spatially related information which shows zoning, floodplains, wetlands, soils, topography, hydrography, geodetic reference framework and so on. The layers combined bring all data in a common spatial reference system. A layer can have its own labeling properties, datasets, and map symbols.
