Exposure has several layers.
Each building has a location, a shape, a use, and people inside it. It also sits in a hazard landscape.
BUILDING-LEVEL EXPOSURE
A building is more than a footprint.
Location is the start. Geometry, construction, occupancy, and estimated population turn a building into useful exposure data.
See the building-level model ↗3D visualization from the OXM presentation. Model attributes may include estimates.
What we are working on.
We run OXM in active projects with partners.
