- Abstract: High-resolution satellite imagery available immediately after disaster events
is crucial for response planning as it facilitates broad situational awareness
of critical infrastructure status such as building damage, flooding, and
obstructions to access routes. Damage mapping at this scale would require
hundreds of expert person-hours. However, a combination of crowdsourcing and
recent advances in deep learning reduces the effort needed to just a few hours
in real time. Asking volunteers to place point marks, as opposed to shapes of
actual damaged areas, significantly decreases the required analysis time for
response during the disaster. However, different volunteers may be inconsistent
in their marking. This work presents methods for aggregating potentially
inconsistent damage marks to train a neural network damage detector.

We present DAVI (Disaster Assessment with VIsion foundation model), which overcomes domain disparities and detects structural damage without requiring ground-truth labels of the target region.
DAVI integrates task-specific knowledge from a model trained on source regions with an image segmentation foundation model to generate pseudo labels of possible damage in the target region.
It then employs a two-stage refinement process, targeting both the pixel and overall image, to more accurately pinpoint changes in disaster-struck areas.

We show how models trained with SSL methods can reach fully supervised performance despite using only a fraction of labeled data.

Building damage detection can be automated by applying computer vision techniques to satellite imagery.
Models must be robust to a shift in distribution between disaster imagery available for training and the images of the new event.
We argue that future work should focus on the OOD regime instead.

These data layers are combined and used as input data for machine learning algorithms such as finding the best evacuation routes before, during and after an emergency or providing a list of available lodging for first responders in an impacted area for first.
