LA Fires - Palisades fire January 2025: Building Damage Assessment

Results from 1/10 using Maxar imagery.

Total of 18,538 structures in this AOI:

11,735 not damaged

6,803 damaged

The result file contains the following fields for each building footprint:

damage_pct_0m – the fraction of the building footprint's area that is classified as damaged by our model

damage_pct_10m – total damaged area within a 10m buffer of the building footprint (including the footprint itself) / building footprint's area (this can be >1.0 but we clip to 1.0)

damage_pct_20m – same as above but with a 20m buffer

damaged – 1 if damage_pct_0m > 0 else 0

unknown_pct – fraction of the pixels within the building footprint that we think are obstructed (clouds, smoke, haze, too dark to evaluate)

Mask from 01/09 using Planet imagery.

6251 are covered by clouds, shadow, and/or smoke

9229 are in the lowest 0-20% bucket

2355 are in the >20% bucket

The result file contains the following fields for each building footprint:
