Enhanced capabilities of IRS P6 LISS IV sensor for urban mapping

In this study, an attempt has been made to evaluate the information content available in IRS P6 LISS IV data for the identification of urban features and urban mapping. Level-III of the urban land use classification at the scale of 1 : 10,000 was successfully attempted for Dehradun city and its environs. A qualitative and quantitative evaluation of IRS P6 LISS IV data has also been done with PAN-sharpened LISS III data. The boundaries of polygon features, road intersections, contrast with the surroundings are more precise on LISS IV data in comparison to merged data. It is also found that 100% more linear features can be extracted with IRS P6 LISS IV data compared to PAN-sharpened LISS III product.
