Satellite-Based Gaza Strip Damage Assessment Overview
	Product ID: 1338 - 10 Mar, 2009 - English This map presents a satellite-based damage assessment for the Gaza Strip following the January ceasefires. Damages have been summarized by the type damage detected and by their estimated occurrence per governorate. Damages to buildings, infrastructure, roads and demolition areas have been identified by standard image interpretation methods with WorldView-1 satellite imagery acquired on 6, 10 and 19 January 2009, and QuickBird satellite imagery of 21 January 2009, at a reduced spatial resolution of 2 meters. Please note: 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 identified in this map underestimate the actual building and infrastructure damages present on the ground at the time of satellite image acquisition.

Sewage Treatment Plant Damage & Outflow Detection, Sheikh Ejlin
	Product ID: 1337 - 10 Mar, 2009 - English This map illustrates damages to the sewage treatment plant located along Road Number 10, in Sheikh Ejlin area. A single impact crater (occurring sometime before 10 January 2009) to the eastern section of a holding pond (70m x150m) caused a massive outflow of sewage, moving an estimated total distance of 1.2km. The estimated area affected by the outflow is approximately 5.5 ha. An area affected by a suspected secondary flow further west has also been marked as well as damage buildings and impact craters in the region. This analysis has been made with imagery at a reduced spatial resolution of 2 meters. Affected buildings were classified either as destroyed or severely damaged by standard image interpretation methods. Ground survey data and photos provided by UNEP from mission 30 January 2009.

Damage Assessment Overview for Gaza & Gaza North Governorates - Update 3

Damaged buildings, infrastructure and impact craters have been identified with Quickbird (16 January 2009) and WorldView satellite imagery acquired on 19 & 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. Destroyed buildings have been defined by the total collapse of the structure or when it was standing but with less than 50% of the roof still intact. Severely damaged buildings were defined as having visible structural damage to a portion of one wall, or where a section of the roof was damaged but with over 50% of the roof still intact. 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.
