An interactive method of photogrammetric orientation is a single-image acquisition method, which allows us to determine 3D-position of the image details based just on one image and digital terrain model. Exterior orientation is a procedure that gives us information about the position and orientation of the camera at the time when the image was taken. Parameters of exterior orientation are derived from a search for the optimal matching of the image detail with the projected DTM. In this graduation thesis we used a selection of archival images of the Skuta glacier from years: 1963, 1982, 1995, 2006, 2010 and 2015. Those images were provided by the Anton Melik Geographical Institute by the Slovenian Academy of Sciences and Arts. For interactive orientation we used existing program, which was created at the Geodetic Institute of Slovenia. For each archival image we determined the parameters of exterior orientation and captured the 3D-circumference of the glacier. Then we calculated area, volume and altitude of the upper edge of the glacier using the ArcMap software. We found out that the area of the glacier decreased by 61% over the period 1963 and 2015. In the years between 1963 and 2006 the volume of the glacier decreased by 371.000 m3. And the altitude of the upper edge of the glacier decreased by 40 m between 1963 and 2015. We have determined how the change of glacier surface is related to the change of the annual air temperature. At the end we evaluated the accuracy of the used method.
