Supported Spatial Resolution
We ingest hazard data from a variety of sources, each using spatial formats such as H3 grids, latitude/longitude coordinates, and standard grid resolutions. We then consolidate these diverse sets into our Insights. We provide our hazard metrics at the resolutions of their supported parcel and census-level aggregations.
