Journal Title:International Journal of Basic and Applied Science (IJBAS)

The paper seeks an empirical methodology for modeling and mapping of the topography using remote sensing (RS) and geographic information systems (GIS) techniques. Firstly this paper examines the mathematical approaches for different surface analysis like contour, hill-shade, slope, aspect and cut/fill analysis. Viewshade analysis was also performed which have a large application on mobile telecommunication in the hilly region. Secondly this paper examines statistical approaches for monitoring surface using LANDSAT-7 ETM+ satellite data, which has wide range of electromagnetic wavelength band, including visible, infrared and thermal bands. Its thermal bands (band 6.1 and 6.2) can detect thermal radiation released from objects on the earth surface. This study has been conducted to develop surface temperature (ST) using 3 sets of algorithm from LANDSAT-7 ETM+. Finally modeled land surface temperature data set was overlaid on digital elevation model (DEM) to find out the relation of surface temperature with variation of altitude of the study area.
