Damage to greenhouses due to the conflict in the Gaza Strip as of 15 February 2024

Year published: 28/02/2024

The damage to greenhouses was estimated using the available Sentinel 1 SAR images on January 04, 05, 16, 17, 28, 29, February 09, 10. This is a proxy measure of damage estimated by implementing the so-called coherence change detection (CCD) algorithm. Three image pairs were used — two pre-event sets and one post-event set. The coherence layers were calculated for each pair to assess the changes. This damage proxy map (DPM) detects the changes in the built-up area. The area of damaged greenhouses was calculated by overlaying the greenhouse distribution layer on the damage proxy map. The grid depicts the severity of damage in localised areas; in each tile the area of damaged greenhouses was divided by the total greenhouse area.
