摘要：High resolution satellite images have reached to a high quality and have proved to be a useful data source for the creation of orthophoto images and different mapping products. A study was carried out in G.lba.. near Ankara for geometric accuracy and feature compilation assessment of high resolution satellite images. Twelve ground control points (GCP's) were established and marked before recording of images. Stereo-pair Ikonos, mono Quickbird and 1:16.000 scaled aerial images were provided free of charge by Inta Inc. (Turkey), Eurimage (Italy) and General Command of Mapping (Turkey). Using photogrammetric, cartographic or Ikonos DEM, various orthophotos have been produced with different combinations of ground control points. Well-recognized 27 checkpoints (CP's) such as junction of roads and field corners have been defined and measured with GPS. P lanimetric coordinates of the checkpoints were also measured on all orthophotos and compared with GPS coordinates. Three regions of different characteristics have been selected in the study area for feature compilation analyses. Three different experienced operators compiled features on these regions for 1:5.000 scaled map productions. Map productions from different sources (Ikonos, Quickbird and aerial images) have been compared within each other. And finally the compiled features have been controlled in field. The geometric accuracy results show that the high resolution satellite images can be used in middle to large scale (1:6.000 to 1:10.000) mapping productions. Moreover feature compilation assessment results reveal that these images are still insufficient with respect to aerial images in terms of determining and identifying of small features
