DETERMINE OF UTILIZATION RANGE OF RESURS DK-1 SATELLITE DATA IN THE FACE OF IKONOS SYSTEM

摘要

The results of investigations conducted within of the realization of research project funded by the Polish Ministry of Science and Higher Education were presented in the article. It was the main aim of the research project the accomplishment of the thorough review of the new Russian satellite data and the qualification their utilization range in the process of generating of the basic photogrammetric products. The methodology of geometrical correction and orthorectification of the source Resurs DK-1 panchromatic images on the basis of the metadata analysis was elaborated. The algorithms of the geometrical correction of the Resurs DK-1 image data which based on the correction modules valid for IKONOS and Quick Bird satellite data and functioning in photogrammetric commercial software Ortho Engine PCI Geomatica were the fundamental of this methodology. Two geometric correction variants were elaborated. In each variant the measurement of image coordinates of the control points as well as check points with use semi-automatically methods implemented in the Ortho Engine software was performed. In present article beside description of the methodology of geometrical correction of Resurs DK-1 satellite images the analysis relating to the influence of the accuracy of delimitation of external orientation Resurs DK-1 images on the accuracy location of the pixels in the orthoimage matrix were presented. It was affirmed that in orthorectification process for obtainment image map fulfilling of the accuracy criterion of the topographic map in 1:10,000 scale is required set of digital elevation points (DEM) with accuracy not worse than 4 m. The comparison of the satellite systems Resurs DK-1 and Ikonos-2 were presented in the article. Comparative analyses concerned to technical and economical aspects were referred to the orthorectification process. Taking into account all comparative factors it was affirmed, that the higher costs on the commercial market, approximate results and the time consuming of the photogrammetric study of scenes Ikonos in the relation to scenes Resurs DK-1 confirm the necessity to interest of new Russian satellite images.
