Land use Land Cover Change Detection for Doon Valley using Arc-GIS & ERDAS Tool
Journal Title: Saudi Journal of Civil Engineering - Year 2017, Vol 1, Issue 1
Abstract
Abstract:The land use change has generally occurred locally, regionally and world wide over the last few decades and will carry on in the future as well the land use change has to be evaluated properly using conventional as well as latest techniques of Remaote sensing and Geographical Information System (GIS) . In order to obtain reliable and latest information on the temporal , spatial and structural change in forest cover and to appreciate the relationship between the current development and its likely impact on land cover / land use and total environment of the region. The variations in the attribution of total area into various specific land cover / use classes have been studied. Satellite images required for estimating land cover are being obtained from earth explorer. The conventional LULC (land use land cover ) map of the study area are obtained by classifying the images of year 2000, 2005,2011 and 2017 using ERDAS IMAGIN 9.2 and Arc GIS. We have devided our area into five different classes i.e. urban, water, agriculture, forest and barren land. Results obtained by analyzing the images shows a drastic increase of built up area, agriculture area and barren land followed by decrease forest area and water area.
