Remote Sensing and GIS Applications on Change Detection Study in Coastal Zone Using Multi Temporal Satellite Data

Abstract

Coastal zones are most vulnerable for land use changes in this rapid industrialization and urbanization epoch. It is necessary to evaluate land use – land cover changes to develop efficient management strategies. The main 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 changes 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’s requirements, updating of landuse mapping is required to various departments. The aims of this study it has been observed that the important coastal land use types of Vedaranniyam coast (Creeks, Rivers) have been reduced drastically in their extent due to reclamation, dredging, tipping and other anthropogenic activities along the coastal zone.
