CHANGE DETECTION OF THE LAND USE LAND COVER CATEGORIES AT LEVEL-II CLASSIFICATION USING MULTI TEMPORAL SATELLITE DATA: A CASE STUDY OF JODHPUR DISTRICT, RAJASTHAN.

Abstract

Transformation of Land use Land cover is a dynamic process that takes place on the Earth’s surface and becomes a basic component in current strategies to manage natural resources and to monitor environmental changes. Remote sensing and GIS are important tools and techniques for monitoring and assessment of land use land cover change status, which can be helpful to decide the strategies for productive use of land for sustainable development. Therefore, it is important to detect the land use or land cover changes for sustaining growth and development of any region. The objective of this paper is to analyse the land use land cover changes over the last 24 years in Jodhpur district, Rajasthan, using multi season satellite data of 30 meter spatial resolution namely, Landsat-5 TM for 1993 and Landsat-8 OLI/TIRS for 2017. This paper has prepared the land use land cover status map on 1:50000 scale with the help of manual digitization technique for the years 1993 and 2017. Later, the change detection in land use land cover changes from 1993 to 2017 has been calculated using ArcGIS software. Land use land cover classes are classified into various categories such as built-up land, kharif crop, Rabi crop, double crop, fallow land, forest, scrub land, dunes, Barren/Rocky area, Quarrying, Lake/Reservoir/Tank, and others for the years of 1993 and 2017. The result of the study shows the expansion of agricultural land, built-up land, Quarrying and other manmade area during this time period and at the same time scrub land, dunes and barren rocky area are decreased. This has significant impact on the livelihood of the local community.
