TOPMODEL is a semi-distributed hydrological model in which the distributed predictions of catchments response to rainfall are made. In this process of simulation, Digital Elevation Models (DEM) is required to provide the values of parameters, such as topographic index, cumulative area of catchment and distance from catchment outlet; thus DEM play a dominant(More)
Object-oriented change detection is more practical than per-pixel change detection when we survey change information of land-use using remote sensing image. A kind of land-use change detection based on patch objects of remote sensing image is studied in this paper. The patch objects of image come from the polygons of historical vector land-use map.
