Physical and Cultural Change Detection Through Remote Sensing and GIS Techniques: A Case Study on Surrounding areas of Churni River, West Bengal

Now a day Remote Sensing and Geographical Information System (GIS) is widely used technique to analyse physical as well as cultural geographical elements. In this paper an attempt has been made to study the changes in land use and land cover of surrounding areas of Churni River for fourteen year time period 2004-2017. The study was carried out through Remote Sensing and GIS approach using Toposheets, Resourcesat-2, LANDSAT images, Google Earth Pro software. The techniques of supervised classification of Satellite image has been used to prepare Land use and Land cover map. The change of Land use and Land cover are a result of long-term interaction between humans and natural environment. The study revealed that the built-up area expanded very high rate. On the other hand areas under agricultural land, water bodies, vegetation have decreased due to the rapid increasing of population during the study period
