- Abstract
Remote Sensing (RS) and Geographic Information Systems (GIS) are becoming powerful tools in climatological
modelling. This study proposes an empirical methodology to prepare digital data set of land use/land cover, soil and
digital elevation model (DEM) using RS and GIS techniques. The study area is Gangetic West Bengal and its
neighborhood in the eastern India, where a number of weather systems occur throughout the year. Gangetic West
Bengal is a region of strong heterogeneous surface with several weather disturbances. Standard false color composite
(Std FCC) bands (green, red and near Infrared bands) of LANDSAT-7, ETM+ sensor are used to produce land
use/land cover dataset. DEM is built using the contours and spot heights which are collected from Topographical maps
of the region. With the help of soil region map of West Bengal and soil region map of India the soil texture dataset is
built. All the data sets are converted to the spatial resolution of 1km and 5km, which can be used as the independent
variables for climatological modelling (specifically air temperature modelling) of the study area.
