UNOSAT Gaza Strip Damage Assessment from Satellite Imagery, October 2025

A geospatial dataset from the United Nations Satellite Centre (UNOSAT) assessing structural damage in the Gaza Strip as of 11 October 2025. The analysis, based on satellite imagery comparisons with 16 earlier dates, identifies 198,273 affected structures, including 123,464 destroyed, and estimates 320,622 damaged housing units. This preliminary analysis indicates a 4% increase in total affected structures and an 18% increase in destroyed structures compared to a July 2025 assessment.

Use Cases

• Mapping the spatial distribution of structural damage based on damage severity classifications mentioned in the description.
• Analyzing temporal trends in destruction by comparing damage counts against the 16 reference dates listed in the description.
• Estimating displacement and humanitarian needs based on the reported figures for damaged housing units and population movement.
• Prioritizing reconstruction efforts by identifying governorates, such as Gaza and North Gaza, with the largest reported increases in damage.

Strengths

• Provides specific damage counts, including 123,464 destroyed and 198,273 total affected structures.
• Uses multi-temporal analysis, comparing imagery from 11 October 2025 against 16 distinct earlier dates.
• Includes sub-national detail, reporting damage increases for specific governorates like Gaza and North Gaza.
• Quantifies displacement, reporting 379,851 people displaced in September and over 0.5 million in October 2025.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is described as a preliminary analysis and has not yet been validated in the field.
