The supervised classification was carried out on the six reflective bands and ground truthed. The classification results were then further refined using ancillary data, visual interpretation and expert knowledge of the area along with GIS. Post-classification change detection then generated a change image in the form of cross-tabulations. Fifteen land cover classes existed within the area, and reclamation processes during the 1990's changed them substantially, with conflicting changes being caused primarily by lack of both stability and consistency in the government's land use policies. The result was extensive vegetation degradation and water logging in parts of the study area. ER -
