Answer 1

Answer: (A), (B), (D)

Layers are the thematic maps prepared and stored in the GIS for analytical purposes.

A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. It analyzes spatial location and organizes layers of information into visualisations using maps and 3D scenes. Spatial data represents the location, size and shape of an object on the Earth. Attributes provide extra information apart from the location. GIS technology applies geographic science with tools for understanding spatial relationships. It uses both hardware and software systems. GIS applications include cartographic, photographic, and digital data as well as data in spreadsheets. GIS technology allows all these different types of information to be overlaid in a single map.
