GIS & GROUND WATER

A Geographic Information System (GIS) is an integrated set of hardware and software tools used for the manipulation and management of spatial (geographic) and related attribute data to digitally represent and analyse the geographic features present on the earth’s surface and events taking place on it.

A GIS is an information system designed to work with data referenced by spatial/ geographical coo-ordinates. This can be understood by the help of various definitions given below.

GIS is a computer-based tool for mapping and analysing the things that exist and events that happen on the earth. Burrough (1986) defined GIS as “ set of tools for collecting, storing, retrieving at will, transforming and displaying spatial data from the real world for a particular set of purposes. Arnoff (1989) defined, GIS as “ computer based system that provides four sets of capabilities the handle geo-referenced data.

The methodology involves generation of thematic maps showing land use/ cover, type of water lands, forest cover/types, surface water resources, drainage pattern, potential ground water zones, geomorphology (landforms), geology (rock types, structural details, mineral occurrence), soil types, etc. using satellite data. By integrating all the data, i.e., superimposing different geomorphologic layers, ground water level contour maps, ground water flow lines, we can delineate.,

Identification Of Recharge Area

Demarcation of sites for percolation tank and check dams for recharge to ground water, afforestation, agro-forestry and agro-horticulture, etc.
