Abstract

The application of Russian satellite images with a precision of over 2m in order to review topographic maps up to a scale of 1: 25,000 was carried out within the framework of a joint project by Belgium and Poland. The KVR-1000 high-precision image on the scale of 1 : 220,000 on Zeiss / Intergraph photoscan has been scanned as a topographic map of the city of Warsaw in the large
format of the Intergraph Scanner ANAT each 3640.
Both Raster images have been analyzed using digital image processing and digital cartography techniques in order to update the changes from 1983 (the date of topographic map revision) to 1992 (i.e. the date of acquiring satellite images). To achieve the result, I'S System 600 and Intergraph ISI-2 software systems installed in the SURFACES lab at the University of Liege, Belgium were utilized.
Like the previously used methods, samples from areas that had changed were introduced to improve the quality of the KVR-1000 digital topographic maps by the SPOT auxiliary data. The KVR-1000 satellite image can be used with acceptable accuracy in order to update the land features on topographic maps in digital form up to a scale of 1: 25,000.
