Enhanced geographic information system application using IRS-1C dataApotential for urban utility mapping and modelling

The tools of geographic information system (GIS) which can be used in a variety of ways to address the local problems of rapid urbanization have been discussed. With the availability of high spatial resolution data of IRS-1C many new ways of looking at urban utilities and environment have been illustrated. The new GIS models which can be adopted on an operational basis by developing and linking data bases in spatial and non-spatial form down to cadastral level have been explored. Day-to-day problems of the urban dwellings, i.e., traffic and transportation, greenery, solid waste disposal, pollution, location of new layout for urban growth, road alignments, etc., have been given a new look under the GIS environment with possibilities arising from the high resolution colour images of IRS-1C satellite.
