Methodology for the Preparation of Basemap

The primary purpose of a Base Map is to provide general information about spatial patterns, provide  specific information about particular locations, while serving as a base for overlaying various layers of  information, spatial and non‐spatial. The Base Map is a crucial output of the GIS database. It provides  essential information that forms the basis of all further data layers that are added to form the  complete database. Typically a Base Map would involve a geo‐referenced satellite image over which  various data layers are superimposed to form GIS database for Base Map.
