Satellite image maps and topographic maps in scales 1:50 000 and 1:25 000 elaborated digitally

Abstract

Experience with the Russian high resolution space photographs KFA-1000, KVR-1000, KATE 200, SPOT XS and SPOT Pan digital data which have been used in IGiK for map updating, urban mapping and elaborating satellite image maps in the scales 1:50,000 and 1:25,000 and topographic maps in scale 1:50,000 are discussed. KFA-1000 could be used for map updating up to the scale 1:50,000. Two meters resolution KVR-1000 photographs could be used for production of the digital B/W ortho-photomaps even up to the scale 1:10,000. KVR-1000 merged with multispectral SPOT XS data are suitable for production of colour satellite image maps up to the scale 1:25,000. The Dlanimetric accuracy RMSE x,y < +/-0.3 mm in the map scale. Examples or map revision digitally of Warsaw area on the Intergraph ImageStation Imager are presented. Application of digital supervised classification of merged KVR-1000 with SPOT XS data for map revision in the scale 1:50,000 is restricted to some laud cover classes. Accuracy of generating DEM and contours lines from stereo satellite data are also presented. Producing topographic maps of the North part of Cameroon in the scale 1:50,000 on the base of SPOT P stereo digital data on the PRISM/VISTA of the DATRON/International Imaging Systems will be also discussed. Different satellite image maps and topographic maps elaborated digitally and printed as hard copies on the IRIS and offset Rolland devices will be displayed during presentation. The planned new commercial remote sensing satellite systems with 1 meter pixel, size and stereo option will be also discussed.
