| Abstract: | The visualization technology offers an effective means to research the errors of DEM.At present,the methods of DEM error visualizations include error map methods,contour registration methods,two dimension graph methods and multi-dimensional visualization methods etc.Due to the multi-source of the DEM error,it is an emergent problem that how to differentiate and use visualization methods correctly.Thus,this paper researched on the development and applications of the key technology of DEM error visualization,... |
