摘要：The present paper presents the results of the research aimed at the qualification of the range of utilisation of very high resolution Resurs-DK satellite data in the process of generating basic photogrammetric products. The methodology for geometrical correction and orthorectification of the source Resurs-DK panchromatic images based on the metadata analysis was elaborated. The algorithms for geometrical correction of the Resurs-DK image data,based on the correction modules for IKONOS and Quick Bird satellite data functioning in photogrammetric commercial software Ortho Engine PCI Geomatica,were the critical for that methodology. Four variants of geometrical correction were applied. The results of the geometrical correction of the panchromatic scenes ResursDK,based on the parametrical sensor model adapted to the structure of Russian data and rational polynomial coefficients,which were identified based on the control point measurement,were presented. The analysis of the influence of the number and distribution of the control points throughout the scene on the result of geometric correction have been realised in each variant. With a thorough analysis of the individual variants of geometrical correction,that very high resolution Russian satellite data can be corrected with the accuracy level below half pixel of the source image. In the present paper,in addition to the profile of the methodology for geometrical correction of Resurs?DK satellite data,an analysis was presented relating to the influence of the accuracy of delimitation of external orientation Resurs-DK images on the accuracy location of the pixels in the orthoimage matrix. Technical conditions were qualified for the orthorectification process of new very high resolution Russian images. It was found that,for orthoimage generating meeting the accuracy criterion of topographic map scaled 1:10000,there should be a set of height points included,having digital elevation model with accuracy at least 4 m. I was proven that,based on the Resurs-DK satellite data,the orthoimages can be generated whose geometrical accuracy corresponds to the accuracy of the topographical map scaled 1:5000 and 1:10,000 and smaller. However,for that scale range of orthoimages,the geometrical accuracy criterion is met,yet their interpreting capability applies only to the 1:10000 scale.
