Project Details: A Geographical Information System  (GIS) having 70 layers was developed with technical help from RRSSC, Nagpur. Using satellite data, natural resource mapping has been carried out on 1:50,000 scales based on satellite imageries and digital processing. The objective of GIS included inter-alia  Road Information System, Georeferencing of villages (cadastral maps), integration of thematic information and socio-economic data for the generation of action plans, generation of comprehensive plan for water and land resources development and generation of watershed wise site-specific and area-specific action plans for easy implementation by local bodies. Some of the important layers included geomorphology, lithology, transport, soil slope, drainage, watershed, forest etc.

Milestones:      

§        First State in India to develop such a comprehensive GIS with 70 layers

§        Georeferencing of 20,379 village (Cadastral) maps in more than 48,000 sheets was accomplished

§        Drainages not observed in existing maps and cadastral maps have been interpreted and updated using high resolution remote sensing data of GIS which is vital for soil & water conservation

§        Micro watershed boundaries were delineated in relatively flat areas also

§        By understanding the natural resources at parcel level, alternate strategies for land & water resources were developed

Impact:              

·               Based on specific requirements of CEO, Zilla Parishad, Mahasamund, the GIS database helped in identifying potential sites for horticulture and floriculture development. The detailed plan was prepared in a very short time frame. It was for this reason that Chhattisgarh was one of the First States to launch Horticulture Mission.

·               Identification of suitable sites for Industrial Development based on 4 parameters was accomplished in 15 mandays using GIS which otherwise could have taken a year

·               The demarcation of Lakheli – Belar corridor for Chhattigarh State Electricity Board (CSEB) based on 10 various parameters for 400 KV transmission line of 1000 kms was accomplished in 10 mandays which otherwise could have taken 1-2 years

·               Forest Department is using the system for demarcating forest boundaries, estimation of forest density, details of vegetation, firewood, timber etc.,

·               Election Office is using the system for demarcating Gram Panchayat boundaries, Janpad Panchayat boundaries, Vidhan Sabha boundaries, pictoral representation of census data and habitat, analyzing polling trends, tracking of polling party movement and ballot box movement

Water Resources Department is using the system for watershed mapping, water         table mapping, demarcation of catchment areas and submergence areas, ground water simulation including site characterization, model development, post processing, calibration and visualization
