Abstract in different language:	Among the variety of problems in providing 3D information about topographic objects, efficient data collection and model construction are issues for research. The efforts are directed towards improving the tedious, time and man-power consuming process of data generation by applying automation. In this paper, we present a semi-automatic method for acquiring 3D topologically structured data from aerial stereo images. The process involves the manual digitising of a minimum number of points necessary for automatically reconstructing the objects of interest. Validation of each reconstructed object is done by superimposition of its wire frame graphics in the stereo model. The 3D topologically structured data are stored in a database and also used for visualisation of the objects.
