From documents to data
Most of this data is published as documents, not as data
Most of this isn't available as data anywhere you can query. It sits in public documents: flood studies and hazard mitigation plans published as PDFs. We've spent years collecting them and turning each page into data that is checked, kept current, and cited to the exact page it came from.
