The PhD thesis has been partialy performed in the frame of the project, its author is a member of the project group, the project leader is the thesis co-supervisor. In the dissertation we have developed a fully automated procedure for orthorectification of optical satellite images. The resulting orthorectified image is in the national coordinate system and constitutes a suitable source for spatial analyses. The original procedure connects several different methods into a single, robust system for automatic generation of orthoimages. The doctoral dissertation describes the whole automatic orthorectification process, which comprises four basic modules: module for extracting and preparing the metadata, module for automatic extraction of ground control points, module for calculation of parameters of the geometric model, and module for orthorectification. Experiments and results with RapidEye and WorldView-2 images are also presented. The experiments evaluate the procedure for automatic extraction of points, the geometric model, the elimination of gross errors, and the positional accuracy of the orthoimages. The results indicate that the automated procedure produces orthoimages with a positional accuracy of about two pixels or better, even if several gross errors are present among the automatically extracted ground control points.

COBISS.SI-ID: 7257697In the half-hour radio show Images of knowledge broadcasted on a national radio station ARS, Štefan Kutoš hosted dr. Krištof Oštir, head of the Department of Remote Sensing at the Institute of Antropological and Spatial Studies of Research Centre of the Slovenian Academy of Sciences and Arts. His main research area is the application of optical, radar and other imagery of Earth's surface in many fields such as geographic information system, monitoring and forecasting of natural disasters and archeology. In international sphere he is involved in the design of small satellites for Earth observation. In the show, they discussed the definition of remote sensing, the applicability, the possibilites of obtaining and accessing satellite data, radar and laser remote sensing technologies, the processing of satellite data and its applications in archeology, agriculture and natural disasters, and the Slovenian small satellite mission.

COBISS.SI-ID: 39396397The proposed invention refers to a method of determination of coordinates of at least one ground control point on the remotely sensed data, such as satellite imagery, by comparing the coordinates of the second point, for example the road junction, on the reference source. By the process according to the invention, first the obtained satellite imagery is rasterized into several layers, after which at least one working layer is selected. Thereafter, objects on the working layer are filtered to obtain the information of digital layer in binary form. These filtered objects are stored into binary file to be added to the reference source as addtional layer. The reference source is converted from vector shapefile to a raster distance image. This is followed by the approximate placement of the digital image in the binary shape on a raster reference source and the exast placement of the image in the binary form on the raster reference source, resulting in a list of ground control points coordinates.
