Spatial analysis on land use/land cover from IRS-R2 LISS4 FMX data-A case study in Assam University campus, India
Demsai Reang, Aparajita De and Ashesh Kumar Das
Land use land cover (LULC) is a core information layer for scientific study, conservation and administrative tasks. Remote sensing (RS) along with Geographic information system (GIS) can provide such information. Assam university campus is an urban landscape established in a rural background. Spatial based studies help to assess the dynamics of land use in such landscape. The detailed land use land cover components in Assam University Silchar (AUS) using RS and GIS has been studied for the first time. The delineation of AUS campus boundary, spatial analysis and precise mapping of all the different land types of Assam University campus using very high resolution satellite data using visual interpretation techniques has been done. The total area of the campus was estimated to be ca 572 acres. A total of 15 different LULC classes was mapped, where the degraded forest area occupied maximum area (34.56 %). The encroached area (2.06 %) within the campus was also mapped. This paper will help the decision makers and researchers working in this area as baseline information for further detailed studies such as management and monitoring, controlling and planning developmental activities in and around the university campus, conservation of the eco-forest area within the campus etc.
