programme will enable the performance of all orientations, measurement of data for DTM, and generation of an orthophotomap. Stereoscopic observation in the VSD-WIN system will be possible upon selection of two options available to the user: a mirror stereoscope, or polarizing glasses interfaced with a 3D graphic card.

The current condition of the system makes it possible to perform model orientation (internal, relative, absolute), to launch the programme in an autogrammetric modę, and to vectorize a model based on broad possibilities of linę attribute defining (colours, thickness, linę type, layers).

Within the scope of the said plug-ins, software has been provided to algorithms, which allow performing automatic internal (OR_INT_AUTO) and relative (OR_REL_AUTO) orientations. Another step will include implementing procedures of automatic object contour vectorization with a sub-pixel accuracy (part of algorithms developed by Mikrut and Huppert to be implemented from "Feature Extraction" programme, which was created under other, earlier research projects) as well as "feature extraction" modules that are based on neural networks.

The authors intend to make a freeware version of their programme available on the Internet. That version would enable complete working on the photogrammetric station, however confmed to a selected stereoscopic model. Those interested in software developing will be able to do so, by constructing their own algorithms and implementing them, just by means of the "Plug-in" option.
