Space artificial intelligence (AI) comprehensive solution corporations TelePIX released on the 21st the results of its satellite image analysis of the Gaza Strip in Palestine.
TelePIX compared and analyzed images taken by the European Space Agency (ESA) Sentinel-2 satellite on Oct. 21 last year and Oct. 8 this year. Based on the two satellite images, the company applied changes in building reflectance to an AI model to determine destruction, and estimated that 134,959 of a total 322,968 buildings (41.79%) were destroyed over the past year.
Damage continued even after the cease-fire was signed on Oct. 10. Of the 188,009 buildings confirmed to be in normal condition immediately after the cease-fire, 13,503 (7.18%) were additionally destroyed in about a month. This suggests that structural losses continued to occur after the cease-fire.
The area that suffered the greatest damage in the past month was Khan Younis, with a total of 4,788 buildings destroyed. The area is a key major city in the southern Gaza Strip, with a high population density and known as a former trade hub.
During the same period, 2,902 buildings were destroyed in North Gaza, 2,345 in Jabalia, and 2,117 in Gaza City. Major residential areas, refugee camps, and administrative and economic hubs all suffered heavy damage.
This analysis was carried out through TelePIX's agentic AI solution "SatCHAT," covering all processes from satellite image acquisition and preprocessing to change detection and damage quantification.
The company said the satellite images used in this analysis had a relatively low resolution (10 m) to assess damage in densely built-up areas, but it actively used SatCHAT to overcome this. SatCHAT can extract clear damage patterns even from low-resolution images through automatic change detection, damage quantification, and grid-level analysis. Using this solution enables effective analysis of satellite images covering wide areas, allowing faster and more economical identification of initial damage conditions compared with conventional high-resolution imagery.
Choi Beom-gyu, head of TelePIX's rapid response team, said, "In areas that are hard to access, such as during wars or disasters, damage scale can be identified quickly and objectively through an AI satellite analysis solution," and added, "Through SatCHAT, TelePIX will continue to advance the service to turn incidents and accidents around the world into data and provide practical help for recovery and response."
