摘要：Canada's vegetationless North is being mapped with the aid of the GestaltPhotomapper . The automatically created DTM based on the 1:40'000 imagescale results in a dense grid with a point roughly every 8 meters . Inorder to investigate further uses of this DTM in zones with vegetationand extend its applicability to different mapping scales , a test modelclose to Montreal was selected . The DTM was compared to an existing1 : 5 ' 000 map of the same region, giving a good idea of its accuracy withdifferent topography and vegetation . Based on statistical tests ,conclusions were drawn as to the possibility of using the relatively denseDTM for larger scales, especially for cadastral related maps in whichaltimetry is usually without interest .
