The paper is devoted to the issues of a posteriori estimation of the accuracy of the output information products obtained by the integrated data processing unit on the basis of Geoton sensor data of the Resurs-P spacecraft series. Brief descriptions of image processing algorithms at level 1A (stitched image), 2B (stitched image, orthorectified into a cartographic projection) and 4B (pan-sharpening orthoplan) are provided. To assess the level of processing, the accuracy of the geodetic reference is evaluated. Additionally, for products of 1A processing level, the accuracy of stitching is evaluated and the accuracy of combining panchromatic and spectrozonal data is estimated from pan-sharpening images. From the analysis of 90 imaging routes, the following estimates were obtained: the average RMSE of geo-referencing images to a terrain of 9.5 m, the RMSE of intermatrix stitching of 0.3 pixels, the RMSE of combining spectrozonal images of not more than 0.3 pixels. The average time for automatic processing of a route with a duration of 9 s (8.8 GB) was 5 min. for the 2B processing level, and 8 min. for the 4B processing level.
Keywords: Resurs-P spacecraft, Geoton equipment, output information products, georeferencing, intermatrix and interchannel stitching
