Use of Geo spatial tools in catchment treatment planning – A case study of Hidishing irrigation project, Odisha, India

In the present study, an attempt has been made to characterize the natural resources and terrain condition of the catchment of the proposed Hidishing irrigation project using geo spatial tools like satellite remote sensing, Global Positioning System and Geographic Information System. Merged satellite image of Cartosat-1 and LISS-IV sensors and limited ground observations have been utilized for generating the thematic layers. The spatial layers have further been integrated and analysed using different geo spatial tools in GIS platform to generate alternate sustainable land use plan and watershed based suitable soil and water conservation measures for the catchment. The logic developed in this study to generate the site specific action plan items are based on watershed management concept.
