Abstract :
The aim of the study is to generate the land use/ land cover and slope interaction acreage map using modern geospatial techniques of remote sensing and GIS. The seasonal data of Resourcesat-2 LISS-III images and data were used to analyze the dynamics of land use / land cover and slope interaction map of Ri-Bhoi district. Erdas and Arc-GIS softwares were used for classification of land use/land cover. The experiment was conducted in Ri-Bhoi district, Meghalaya which lies between 91°20’30" - 92°17’00" E longitude and 25°40' - 26°20' N latitude covering geographical area of 2448 km2, forest area 869.07 km2, net sown area 222.6 km2 and the total cropped area 251.7 km2.The area has been classified into 21 classes at Level II. Among 21 classes 5 land use classes were selected for land use and slope interaction map. Land use and slope interaction map was generated by intersecting slope and land use land cover map in Arc-Gis10.2. and Erdas software.The highest area observed in abandoned jhum slope 5 (AJS5) (6323.71 ha) followed by abandoned jhum slope 4 (AJS4) (4937.49 ha). The minimum area observed in Rabi crop slope 7 (RCS7)(0.003 ha). However, in case of land use land planning the maximum area found in tree clad area closed area (80247.21 ha) followed by abandoned jhum (16096.20 ha).
