Remote Sensing and GIS Application In Change Detection Study In Urban Zone Using Multi Temporal Satellite

Information on landuse/landcover in the form of maps and statistical data is very vital for spatial planning, management and utilization of land. In the study, Remote Sensing and geographic information system (GIS) were used in order to study landuse/landcover changes. Land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion and sedimentation and soil conditions. The Urban areas are changing due to various human activities, natural conditions and development activities. According to the user requirements, updating of landuse mapping is required to various departments. The aims of this study are to detect land use changes between 1990 to 2005 using satellite images of Land Sat 7 ETM+ (1990) and IRSLISS III (2005) and digital topographic maps have been used. The objectives of the study is to see the landuse/landcover changes in Urban areas and identifying hotspots of land cover changes using multi temporal satellite data and also studying relationship between human pressure on landuse/landcover and its impacts in the vital Urban habitats. Landuse changes have been detected by image processing method in EDRAS imagine. Finally to predict the changes in Urban habitants and landuse/landcover changes occurred. Monitoring of landuse/landcover changes which would help to plan development activities such as major schemes and for used requirements. Change detection has shown that the built up area increased between 1990 and 2005 by 15.83% from 6513.29 ha to 9300.97 ha. Also, the area with irrigated land farms have been decreased to 436.99 ha (2.48%) and the scrub land decreased to 5.19%.
