An integrated approach involving compilation of data from government agencies and institutions, application of spatial and temporal analyses using remote sensing data , Geographic information system ( GIS techniques) and conventional field survey (ground truthing) have been adopted in this study. The vegetation map for Kolar district(talukwise) were prepared based on the interpretation of IRS-1C satellite imageries, using the visual interpretation keys such as tone, colour, texture pattern, association, size, shape, topography and drainage. This involves :

Data acquisition, loading, composite generation and georeferencing
Training sites, Ground truth collection (field data collection)
Signature generation for classification
Extraction of statistics
Demarcation of boundaries 
Villages, taluk  and  district  boundaries  and  road network were 
digitized from SOI toposheets.
Georeferencing has been done by  extracting  ground control points 
from topographical map and using  GPS (Global  Positioning  System). 
Multispectral  image  classification was carried out using Maximum 
likelihood classification technique with the help of training data.
