Land cover indicates the physical land type such as forest or

open water whereas land use documents how people are

using the land.

Prepare thematic maps of the area such as lithology, lineaments,

landforms and slopes from remotely sensed data and other data

sources.

Assess groundwater controlling features by combining remote

sensing and field studies.

Identify and delineate groundwater potential zones through

integration of various thematic maps with GIS techniques

A map displaying the topography of an area, along with

a discussion of topographic features

Soil Depth

The mean depth of the soil layer within the sampling area is assessed

by studying conditions in the terrain, both on the test area and in its

immediate vicinity

Very deep (> 100 cm)

Deep to very deep (> 50 cm)

Deep (50 to 100 cm)

Moderately deep (25 to 50 cm)

Soil Drainage

Soil drainage is soil's natural ability to let water permit through it.

Excessively drained Somewhat excessively drained Somewhat excessive to well drained Well drained Moderately well drained Moderately drained Mod. well to SW poorly drained Imperfectly drained Somewhat imperfectly drained Poorly drained Somewhat poorly drained Salt-pan

Soil Erosion

Soil erosion is the washing or blowing away (by

wind or water) of the top layer of soil
