Land cover change detection is more important to understand the present scenario of the geographical condition of the region, for this analyses SAGA (System for Automated Geoscientific Analysis) software used for calculates the change detection between two different years such as 2008 to 2017. In this study, we collected Landsat 8 and Landsat 5 satellite images with 30m resolution. The change detection classified based on k means cluster analysis in saga software. The clusters are a wasteland, Cultural waste, Follow land, barren land, Water, uncultivated land, cultivated misc and tree, other follow land and the Net area sown. Each one have 87,34,70, 20,23,77,53,53 and 89 km2 in 2008 and 79,51,47,31,41,68,50,60,and 89 km2 in 2017. Change matrix method detected 16% of changes in the study area. Colour occupation is the main resources for classification of this study for that we used unsupervised classification. The changes mainly occur in and around of national highway (NH 44). The major land cover changes are in the center portion of the study area and towards the south-east and North West small changes.
