Systematic Change Detection Approach of Uttar Dinajpur District in West Bengal Using Geospatial Technique

Land use/Land cover (LU/LC) is a significant element to understand the primary human impact over land. The remote sensing and GIS integrated technique has been used to evaluate the change detection analysis of Uttar Dinajpur district of West Bengal during 2001–2019, using multispectral Landsat series data. Supervised maximum likelihood classification technique has been applied for this research. Post classification Accuracy assessment (user’s accuracy, producer’s accuracy and overall accuracy) and Kappa Coefficient were applied to justify the observation. In present study highlighted that the agricultural open land, agricultural area, vegetation and water body mostly affected and sharing area with other categories during 2001–2019 it’s happed only rapidly growth rate of population with pressure on the land. Other hand built up area and tea garden area has increase within study periods.
