Land use/land cover change assessment of Ysr Kadapa District, Andhra Pradesh, India using IRS resourcesat-1/2 LISS III multi-temporal open source data

Abstract

LULC change assessment by the Remote sensing Technology helps in understanding land dynamics effectively compared to conventional field inspection methods. This study provides the spatio-temporal dynamics of LULC classes in the Kadapa District, Andhra Pradesh, India. IRS Resourcesat-1/2 LISS III Multi-Temporal remote sensed data, from Bhuvan -Indian Geo-platform of ISRO is intended to assessment the changes in the study area during the years 2005-2006, 2011-2012 and 2015-2016 over tenure of 10 years. At the end the study area claasified into five major classes namely Built-up, Agriculture, Forest, Wastelands and waterbodies using ERDAS Imagine 2015. The results indicate net change and rate of change of LULC classes over the period of 10 years. Net change in Built-up land is 89.91%(167.12 km2), Net change (decreased) in Agriculture land is 3.76% (256.05km2), Net increment in the Forest land is 2.39 %(114.83km2), Wastelands decreased by 2.92 %(79.09km2), and waterbodies increased by 6.28% (52.9 km2).
