Land Use/Land Cover Information at Various Scales of Remote Sensing Data of Jhunjhunu District, Rajasthan

Abstract

Through the present study, variation in land use, land cover (LULC) with change in scale is discussed. The authors carried out the visual interpretation with the aid of supervised classification, aiming to obtain LULC information at various levels of remote sensing data of district Jhunjhunu of Rajasthan. Remote sensing data of IRS-P6 (LISS-III) standard false color composites (FCCs) on 1:1 M, 1:250,000 and 1:50,000 scales for the period of February 2012 for the interpretation, for entire district area have been used in the study. Finally, a list of LULC categories at different scales has been compiled, highlighting the problems in identifying and delineating the same. The result shows progressive change in the LULC categories with increasing scale and has revealed area variations of different LULC units. The 1:50,000 scale interpretation gives the best result in classification, done in three different scales.
