Online published on 3 January, 2012. Abstract Digital change detection is the process helps in determining the changes associated with land use and land cover properties. Landuse/landcover change detection in the form of maps and statistical data is very vital for spatial planning, management and utilization of land. Remote Sensing and Geographic Information System (GIS) have been used in order to study landuse/land cover changes. The aim of this study is to detect land use changes between 1991 to 2006 using satellite images of IRSIA,D, LISSII,LISSIII,ETM+, TM Landsat ( 19912006) and digital SOI topographic maps. The study has produced a land use/land cover map of Pathankot and Dhar Kalan tehsil at three (1991,2002,2006) point of time in order to detect the changes that have taken place particularly in the builtup land and forest areas. The objective of study is to prepare land use/land cover map for different time periods, analyse the land use changes and evaluate the socio – economic implications of predicted change. Landuse changes have been detected by image processing method in EDRAS imagine9.3, ArcGIS9.3. Monitoring of landuse/landcover changes help to plan development activities such as major schemes and for community requirements. Fifteen year time period of 1 991 2006 shows some major land use changes. During this period of fifteen years 104.02 sqkm areas has undergone positive changes into Cropped Land and Builtup areas from Forest and Fallow land. There is a remarkable increase (69.23sq/km) in the area of Crop Land. Top Keywords Landuse, Landcover, Change Detection. Top |
