LA Fires - Eaton fire January 2025: Building Damage Assessment

Results from 01/11 using Planet imagery.

156,102 buildings in study area

8,682 estimated 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)

Results from 01/10 using Maxar imagery.

31,356 buildings in this AOI:

27,202 in the 0-20 bucket

4,154 in the >20 bucket (4602 with damage>0)
