The Aim of present project work is to The Aim of present project work is to find out ground water prospect of find out ground water prospect of surendranagar district of Gujarat by using surendranagar district of Gujarat by using Remote sensing and GIS technique. Remote sensing and GIS technique.
OBJECTIVEOBJECTIVE The study has been carried out with the following
objectives-
LULC and geomorphology mapping of the study area by using LISS-III satellite imageries in Remote Sensing and GIS environment.
Using GIS tool (Union & resolve) to generate ground water prospect of Surendranagar district.
INTRODUCTIONINTRODUCTION Surendranagar is located at 22° 43’ 53” N
latitude and 71° 38’ 12” E longitudes, belongs to the semi-arid region of Gujarat .
The district is of area 10436.30 Sq Km having population 15,15,147.
The annual average rainfall is very low.
Groundwater is generally saline. Irrigation is totally dependant on rain.
The district has lowest amount of industrial investment, due to scarcity of water.
METHODOLOGYMETHODOLOGY Selection of area .

Using union tool of Arc GIS to generate Union of LULC & Geomorphology layer.
METHODOLOGYMETHODOLOGY
Generation of Matrix from Union..
METHODOLOGYMETHODOLOGY
Assigning of GWP (Ground water prospect).
METHODOLOGYMETHODOLOGY
Calculation of resultant ground water prospect values in union file .
METHODOLOGYMETHODOLOGY
The dissolving process of GIS on ground water prospect values of union file is carried out in order to generalize the GWP polygons.
The statistic type used to summarize attributes is added to the output features class as a single field.
METHODOLOGYMETHODOLOGY
Generation of final output i.e. ground water prospect map.
METHODOLOGYMETHODOLOGY
CONCLUSIONCONCLUSION The study has shown that by using the
Remote Sensing and GIS technique, the GWP map of selected Surendranagar district could be generated with less effort and in less time along with limited field checks as compared to the conventional methods.
