Improving the accuracy of digital terrain models

Abstract: The change from paper maps to GIS, in various kinds of ge- ographical data analysis and applications, has made it easy to use the same spatial data for dierent

Theoretical analysis of building height estimation using space- borne sar-interferometry for rapid mapping applications

Abstract: The great potential of space-borne SAR images for semi- or fully-automatic mapping of topographic features has been shown by many approaches. While most of them focus on 2D mapping of topographic features, some preliminary research on the complex task of automatic delineation of 3D information in urban environments has been initiated in recent years. In this paper, we analyze the capabilities of new space-borne interferometric SAR missions – in particular the German TanDEM-X mission – with respect to their potential of deriving building heights. To this end, we summarize the mathematical framework and carry out a thorough analytical accuracy analysis involving various sensor and scene parameters.

Applications of SPOT-7 tri-stereo imagery in deriving the surface topography and mass changes of glaciers in Indian Himalaya

Abstract: The present study describes the application of satellite images of SPOT 7, acquired on 10 October 2014 for producing the high spatial resolution digital elevation models of five glaciers in...
