The assignment involved providing assistance to five forest divisions to carry out survey and to prepare accurate forest boundary maps for notified forest areas. The existing maps generated by conventional methods of chain and compass survey was lacking the geo references for integration into secondary data such as topographic maps and satellite imagery and lack of essential features such as drainage, roads, location of settlement and water bodies for correct identification on ground. SPARC carried out boundary survey of notified blocks and integrated them on to a divisional geo-database with thematic features such as forest administration boundary, roads, settlement, rivers & drainage, watershed boundary etc. notified area wise survey maps and reports were prepared to support existing notification. The assignment also involved delivery of maps for each forest administrative units (division, section, range, beat) compilation in form of atlases and capacity building of forest field officials.
The GIS based geo-referencing of the forest blocks helped in
- Preparation of precise forest boundary maps showing pillar positions with forest thematic features
- Development of accurate forest land record for efficient forestry management
- Platform for formulation of forest conservation/ aforestation schemes
