摘要

The paper concerns the contribution of high resolution satellite images to the production of base-maps and cartographies for archaeological research, using both during field work and in GIS dedicated to Cultural Heritage. Particularly, some experiences conducted during researches on Turkish and Iraqi archaeological sites are presented, where the use of satellite images was necessary because of both large scale cartographies and aero-photogrammetrical photos are not available.rnIn the case of archaeological surveys in Hierapolis of Phrygia (south-western Turkey) they provided a fundamental tool for the research on the ground and for the analysis and management of data in the archaeological GIS of the territory. Ikonos-2 and QuickBird-2 images were ortho-rectified with the use of GCPs (taken with a differential GPS) and with DEMs and DSMs processed thanks different remote sensing data, radar (SRTM) and optical (Ikonos-2 and ASTER stereo-pairs), for the creation of space-maps and the extraction of cartographical elements: these (hydrology, modern topography, field boundaries, archaeological remains and traces, etc.) were used with the aims of the creation of new maps for archaeological purpose (the orography was extracted from DEMs) and the update of the existing ones. In the case of some ancient sites studied for the contextualization of the objects showed in the Virtual Museum of Iraq, high resolution images of the same satellites (and of WorldView-1) were ortho-rectified without GPCs and used for the creation or the update of the archaeological maps (generally very old), on which plans of excavated structures, recent discoveries, and archaeological traces and paleo-environmental elements were geo-referenced.
