High-resolution images have to be geometrically and precisely processed with ground information, such as ground control points (GCPs) and digital elevation models (DEM) to generate accurate map products and 3D geospatial information. Consequently, the 3D multi-sensor physical model developed at Canada Centre for Remote Sensing for medium-resolution(More)
The National Land and Water Information Service (NLWIS), an Agriculture and Agri-Food Canada (AAFC) initiative, is tasked with mapping ‘circa 2000’ land cover for agricultural areas of Canada with an overall accuracy of greater than 85%. The method for mapping land cover is being developed using a Decision Tree (DT) classifier (see5 software) with specific(More)
A preliminary version of the 3D multi-sensor physical model developed at the Canada Centre for Remote Sensing was developed for the generation of digital elevation models (DEM) from SPOT-5 HRS in-track stereo images (pixel of 5 m by 10 m). Even if three accurate ground control points (GCPs) were enough to set-up the stereo bundle adjustment, ten stereo GCPs(More)
