Land Use/Land Cover Classification and Change Analysis for Ganges River Basin from 2000 to 2010
Abstract
Land use and land cover maps are essential to study how the earth surface change over time. The growing amount of available remote sensing images, especially the well archived Landsat images with 30 meters resolution, have been used to conduct supervised classification for land use and land cover maps. In the past 20 years, Ganges River basin has gone through rapid urbanization. To monitor the change of urban, agriculture and other land cover types, land use land cover maps are needed. In this research, we conducted supervised classification on Landsat surface reflectance product in 2000, 2005 and 2010 in Ganges River Basin based on GlobeLand30 2000 and 2010 product. We then used a novel post-classification correction to improve the classification results. At last, a change analysis is conducted to understand how the land use and land cover in Ganges River Basin evolve from 2000 to 2010 with 5 years gap.
