Abstract
It is well known that remotely sensed data from satellites have the advantage of synoptic view of large areas repetitively in a multi spectral mode. The Landsat series of satellites since 1972 provided spatial resolutions starting from 80 m to 30 m and later SPOT satellites provided resolution in panchromatic mode up to 10 m. The scales of mapping improved with resolution, making it possible to map up to 1 : 50,000 scale. Indian Remote Sensing Satellite series started in 1988 with IRS-IA and later IRS-IB followed by IRS P2 provided resolution which made it possible to map up to 1 : 50,000 scale. Towards realizing the potential high resolution of IRS-IC data, an attempt has been made here to see how best this data can be used for the development of rural areas in our country. Three study areas have been selected in different parts of the country for this study. They are (i) part of Dharmapuri district in Tamil Nadu, (ii) part of Chandrapur district in Maharashtra, (iii) part of Ahmedabad district in Gujarat. PAN data of 5.8 m resolution and multi spectral data of 23 m resolution have been studied using the powerful computer systems available. Compatibility of IRS-IC data by overlaying on cadastral maps has been studied and it was found that there was a very good geometric fidelity of the satellite data when overlaid on cadastral maps of different study areas.
