Cadastral Level Natural Resources Planning : Use of Remote Sensing & GIS Techniques for Watershed Planning

Bok av Lakkad Arun
Watershed development and management programs are being implemented by various Government agencies and NGOs nowadays. These agencies collect the information by conventional survey methods for making watershed action plan. The process of making action plan is cumbersome, time-consuming and costly. Satellite imagery has unique ability to provide the actual synoptic views of large area at a time, which is not possible for conventional survey methods. Integrated approach using remote sensing and geographical information system (GIS) provides cost effective support in resource inventory. In the present study an attempt has been made for watershed planning using remote sensing and GIS techniques, with the main objective of fulfill the gaps between requirement and utilization of existing natural resources of a village regarding agricultural development.A micro-watershed (5G1D2b3g) having an area of 602.83 ha. was selected for preparing the action plan. Information available from thematic maps prepared through RS Image & GIS was used for designing various conservation measures The total storage capacity fulfils the gap of water requirement at 60 percent probability of rainfall.
