摘要：The acquisition of 3D data and their integration in information systems which are mainly used for topographic issues arevery increasing in the last years. The enlarged needs in 3D information appear with the development of the complexity ofthe processings in topographic information systems. The middle-sized and big cities, which have a large extent, havealso important care for fitting out and want to dispose and make use of as complete as possible datasets. These datasetsshould integrate the third dimension.For responding to such a sort of new needs, the group "Photogrammetry and Geomatics" of the LERGEC-ENSAISLaboratory of the ENSAIS works in the definition and the testing a 3D modelling of objects in urban landscapes. Thismodelling is then implemented and tested in a topographic information system coupled with an experimental digitalstereophotogrammetry software, TIPHON developed at ENSAIS. This digital system makes it possible to acquirerationally geometric data, and in the same way to learn the different steps of the orientation of the digital stereopairs andthe processing of stereoplotting
