1.	What is the importance of preparing layers in GIS? Write an example.
Answer» With the help of GIS software, spatial data can be stored as different layers. When the features of the surface of the earth are made as layers, we can separate the data that we need to make tables and maps easily. Example: Using QGIS, a GIS software, different data about India are made into separate layers. Different layers to show the states in India, natural resources, mountains, cotton cultivated regions and jute cultivated regions are made. Maps obtained as different layers in this manner can be used for different analyses.
