Geographical Information System (GIS)
A Geographical Information System (GIS) having 70 layers was developed with technical help from Indian Space Research Organization (ISRO) through Regional Remote Sensing Centre (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.
Chhattisgarh GIS Project’ with the objectives of generation of natural resources database for the state of chhattisgarh on 1:50000 scale using IRS LISS-III data, development of spatial database for road network using IRS PAN data and geo-referencing of village (cadastral) maps using high resolution IRS PAN + LISS-III data. Having been convinced about the utility of such an information system under chhattisgarh GIS Project, Government of Chhattisgarh generated resources of around 20 crores i.e. funded by Panchayat & Rural Development Department, Government of Chhattisgarh.
The Chhattisgarh infotech and biotech Promotion Society (CHiPS) has adopted a planned approach for the implementation of “Chhattisgarh GIS Project”. The following key persons were involved in the successful implementation of the project.
1. Hon’ble Chief Minister, Government of Chhattisgarh
2. Chief Secretary, Government of Chhattisgarh
3. Hon’ble Minister (IT), Government of Chhattisgarh
4. Hon’ble Minister (Panchayat and Rural Development Department, Government of Chhattisgarh)
5. Secretary (Panchayat and Rural Development) , Government of Chhattisgarh
6. Special Secretary(IT & BT) , Government of Chhattisgarh & CEO, CHiPS
7. Director, RRSSC, Nagpur
8. Dean, IIT, Kanpur
- 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
- Prioritization of watersheds and water resources development plans of priority watersheds.
- Rural road connectivity to villages through the forest & Forest Management Information System (FMIS).
- Identification for suitable sites for horticulture and vegetable crops in Mahasamund Districts.
- Identification for suitable sites for developing PURA (Providing Urban amenities in Rural Areas).
- Hydrology Project of Chhattisgarh State (Funded by World Bank).
- Election Commission GIS for delimitation of constituencies.
- Identification for suitable areas for sitting industries in the state, Chhattisgarh State Industrial Development Corporation (CSIDC).
- Optimal routing of High Power Transmission Lines, Chhattisgarh State Electricity Board.
- Developmental Planning of major towns and New Raipur City of Chhattisgarh State, Department of Town and country Planning, Raipur.
- 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.
