This map presents a preliminary and on-going satellite-based damage assessment for the Governorates of Gaza and Gaza North. Damaged buildings, infrastructure and impact craters have been identified with Quickbird and WorldView satellite imagery acquired on 16, 10 & 6 January 2009, and received at a reduced spatial resolution of 2 meters. Pre-crisis Ikonos satellite imagery from June 2005 was also used. Affected buildings were classified either as destroyed or severely damaged by standard image interpretation methods. Please note: Buildings not marked in the map as damaged does not imply the buildings are undamaged, only that damages were not identified with the available satellite imagery at the time of map publication. Because of the reduced spatial resolution of this satellite imagery, the confidence level for damage identification within dense urban areas is significantly reduced. It is highly probable, therefore, that the damages currently identified in this map underestimate the actual building and infrastructure damages present on the ground at the time of satellite image acquisition. This damage map will be revised and updated as additional analysis and ground information is available. Please send any additions/corrections to UNOSAT.
