OBJECTIVE & MATERIALS
To prepare natural resources inventories by analysis of
Satellite data, Topographic map & other existing datas and
Identifying the Priority areas for the sustainable development
of resources by integration of relief, slope, aspect, geology,
landform, soil type, drainage density, land use/land cover,NDVI,
Draught prone etc. information using GIS.
Survey Of India Topographic map 1:50,000 scale ( 48P/4 and 48P/8 )
Satellite Imagery(IRS LISS-III)
Arc GIS 9.2
Erdas imagine 8.7
About 168 km2 area is under high priority condition, that needs
soil & water conservation.
As fund comes to the Panchayat and municipality ,accordingly
action plan should be taken.
Conservation of water and soil in the agricultural sector is
Soil covered by crops, slows down run-off and minimizes
evaporation losses and soil loss Hence, fields should not be
left bare for long periods of time.
