2. METHODOLOGY AND DATA USED 
Cloud free digital geocoded data of IRS 1D LISS III of 
November, 2000 (Figure-2) was used for the present study. The 
data was geometrically and radiometrically corrected using 
transformation models derived from SOI toposheets. The study 
was done to extract information pertaining to land use/ land 
cover pattern in the study area using SGI-02 work station 
through ERDAS Imagine software. The land use/ land cover 
pattern was delineated and classified under the classification 
system developed by NRSA, India (NRSA, 1990). Limited 
ground truth had been collected to check the doubtful areas in 
the interpretation category and final map was prepared. Area 
statistics was generated showing the aerial extent of various 
land use/ land cover pattern.

3. RESULTS AND DISSCUTIONS 
The land use/ land cover map generated from the satellite data 
clearly brings out, spatial information on settlements/ Built up 
lands, agriculture lands ( upland, crop fallow), surface water 
bodies and forest resources informations (Figure-3). Area 
statistics and spatial distribution of different land use/ land 
cover pattern is shown in table-1. 
Settlements/built-up areas: 
In the satellite image the village settlements are seen as 
clusters of discrete red patches, due to the presence of green 
cover in the form of orchards. However, incorporating the 
information from Survey of India topographical maps on to 
the classified data further refined the settlement areas. 
Agriculture areas: 
tune of 6570 sq. km. i.e., about 59 percent of the total 
geographical area of the district. 
Forest resources: 
The forest resources under study fall under the forest type of 
Tropical semi evergreen, Tropical moist deciduous and Tropical 
moist/dry deciduous forest and Savannah-hill top grasslands. The 
forest crown cover density has been estimated combining both 
dense and open type of forests to the tune of 2550.75 sq. km, i.e., 
about 22.8 percent of the total geographical area of the district. 
Land, as notified under the Forest Act and those lands with various 
types of vegetative cover outside notified forests, in which 
vegetative cover is less than 20% and also scrub lands having 
hardly any vegetative cover are classified as degraded wastelands. 
These wastelands are reported to be mostly in reserve forestlands 
and also outside covering 1693.43 sq. km, i. e., 15.2 percent of the 
geographical area of the district. 
Surface water bodies: 
All the water tanks including small reservoirs amount to an area of 
124.69 sq. km. have been delineated from the satellite image in 
conjunction with SOI toposheets. 
Other categories: 
The other land use / land cover classes of sandy areas including 
coast sands and some marshy areas occupy an area of 39.14 sq. km.
