Remote sensing and GIS have become powerful tools for studying land use/land cover changes. The present study aims to assess the land use/land cover changes in the study area using remote sensing and GIS techniques. The study area, Kolkata metropolitan area, has undergone rapid urbanization and land use changes in recent years. Multi-temporal satellite images of 1980, 1990, 2000, and 2008 have been used to study the land use/land cover changes. The images have been classified using a supervised classification technique. The results show significant changes in land use/land cover patterns over the study period. The urban area has increased significantly, while the agricultural land and vegetation cover have decreased. The GIS analysis reveals that the changes are concentrated in the areas with high population density and accessibility.
Airborne (drones, aircraft) versus spaceborne (geostationary and sun-synchronous satellites). Remote sensing and GIS have become powerful tools
Geospatial technology has transformed how we understand, analyze, and manage our planet. At the intersection of this revolution are Remote Sensing (RS) and Geographic Information Systems (GIS). For students, researchers, and professionals looking to master these fields, Remote Sensing and GIS by Basudeb Bhatta has established itself as an essential, definitive textbook. Multi-temporal satellite images of 1980, 1990, 2000, and
Instead of a PDF, a terminal window snapped open. Lines of green code began scrolling at impossible speeds. Elias reached for the power button, but the screen froze on a single, high-definition image: a satellite render of his exact current location—a remote research hut in the Zanskar Range. The urban area has increased significantly, while the
