Abstract
Abstract. The recent mass destructions of monuments in Iraq cannot be monitored with the terrestrial survey methodologies, for obvious reasons of safety. For the same reasons, it’s not advisable the use of classical aerial photogrammetry, so it was obvious to think to the use of multispectral Very High Resolution (VHR) satellite imagery. Nowadays VHR satellite images resolutions are very near airborne photogrammetrical images and usually they are acquired in multispectral mode. The combination of the various bands of the images is called pan-sharpening and it can be carried on using different algorithms and strategies. The correct pansharpening methodology, for a specific image, must be chosen considering the specific multispectral characteristics of the satellite used and the particular application. In this paper a first definition of guidelines for the use of VHR multispectral imagery to detect monument destruction in unsafe area, is reported. The proposed methodology, agreed with UNESCO and soon to be used in Libya for the coastal area, has produced a first report delivered to the Iraqi authorities. Some of the most evident examples are reported to show the possible capabilities of identification of damages using VHR images.

This paper illustrates the study of the use of pansharpening techniques on very high resolution satellite imagery to localize and highlight the damages suffered by monumental and historic sites in Iraq during the recent years
All the images were ordered in “bundle” version so the panchromatic and multispectral were available for each acquisition

Summary
This paper illustrates the study of the use of pansharpening techniques on very high resolution satellite imagery to localize and highlight the damages suffered by monumental and historic sites in Iraq during the recent years. They were acquired before and after the critical period of 2010-2015 years, characterized by the main destructions. Before these images are ready to be used for interpretation they have to be processed according one of the several data fusion approaches available. In the field of the remote sensing, the introduction of high resolution satellite sensors has required the development of specific techniques as
