Mapping Damage in Gaza

A researcher at UCL's CASA has released a new interactive mapping tool which can help researchers and news agencies "estimate the number of damaged buildings and the pre-war population in a given area within the Gaza Strip". The Gaza Damage Proxy Map is based on an earlier tool which was developed to estimate damage caused by Russia in Ukraine.

The Gaza Damage Proxy Map colors individual buildings in the Gaza Strip to indicate the probability that the building has suffered damage since October 10, 2023. If you use the map's drawing tool you can highlight an area of the Gaza Strip on the map. The Gaza Damage tool will then automatically estimate the number of damaged buildings in the highlighted area and the estimated affected population. The percentage of the buildings damaged in the area is also calculated for you. If you select individual buildings on the map you can view information on the date of the damage and view a link to the source media for the damage report.

The Gaza Damage Proxy map uses Synthetic Aperture Radar imagery captured by satellites to detect damaged buildings. By measuring the change in the intensity of these radar waves since before the Israeli attacks on Gaza it is possible to estimate the probability that individual buildings have been damaged. Damage points from the UN Satellite Office (UNOSAT) have also been used to validate the accuracy of the damage detection algorithm used by the map. The map itself also includes an optional layer which adds geo-located footage of strikes and destruction in Gaza as triangular map markers.

You can learn more about the methodology used to estimate building damage in Gaza in the Bellingcat article, A New Tool Allows Researchers to Track Damage in Gaza. The Ukraine Damage Assessment Map allows you to carry out similar analysis of the estimated building damage caused by Russia in Ukraine.
