Spatio Temporal Changes of Land Surface Features: Study on Ward-9 of Khulna City Corporation Area

Abstract

This research aims to determine the effect of land use land cover (LULC) on terrestrial 
surface temperature in ward level of Khulna City Corporation area. This study also 
explores the relationship of LULC change and Land Surface Temperature (LST) from 
2007-2017. To fulfill the aims, this study followed three steps. Cloud free satellite images 
Landsat 7 ETM+ and Landsat 8 were collected from USGS (United States Geological 
Survey), followed by supervised classification of images. LULC indices such as 1) NDVI 
(Normalized Difference Vegetation Index) 2) NDBI (Normalized Difference Built Up 
Index) 3) MNDWI (Modified Normalized Difference Water Index) were analyzed by 
using Arc GIS 10.5 to explore the relationship between LULC and LST. The NDVI value 
indicates that agricultural land, vegetation and waterbodies have been decreased 
rapidly due to urban growth for residential, commercial and other developments. LST 
was positively correlated with NDBI and negatively correlated with NDVI and MNDWI 
over the time, where the R2 value is significant.This paper suggests to take appropriate 
planning measures to reduce the rising temperature in urban areas.
