For measuring was used universal measuring station Trimble VX Spatial Station (Fig. 1 and<br />
Tab. 1).<br />
Measurement was preceded by terrain reconnaissance and was stabilized three locations. Scan<br />
starts by setting device parameters such as temperature, pressure and others. The next step is<br />
determining the extent of the scan, in our case, the limitation on the big screen used a closed<br />
polygon. During the scanning is necessary to specify the scanning parameters, horizontal and<br />
vertical interval and the quality of the images. The actual scanning is done automatically<br />
measuring station. The result is a set of scan points of each location, which shall be connected<br />
to the resulting cloud of points and panoramic images. Spatial data processing is done in the<br />
program Trimble, RealWorks v6.5.<br />

Figure 2 shows the spatial model created using the network of triangles, called the Mesh<br />
view. Mesh model allows assigning images to each surface for the purpose of visualization. In<br />
