Common questions
What is DaedalMap?
DaedalMap is geographic reference infrastructure: durable loc_id identities, reusable geometry, published crosswalks, and maintained data packs. Maps, Research, Ops, downloads, conversion, and agent tools are ways to use that foundation.
What is a loc_id?
A loc_id is DaedalMap's identifier for a place, such as USA-VA-059 for Fairfax County, Virginia. Coordinates, names, and codes that describe the same place resolve to the same loc_id. Postal areas, watersheds, and other geography families keep their own identities, and published crosswalks connect them.
Do I have to restructure my data?
No. Try Your Data keeps every original column and adds loc_id and admin_level. When a code could belong to more than one geography system, it asks you to confirm before converting.
What happens to rows that do not resolve?
They stay in the output, marked with the reason, so you can fix the source values or drop them deliberately. A row that matches only at state level is reported at state level, not presented as a county match.
What do I get without paying?
Testing a sample is free. You can also inspect the data and geometry catalogs, download eligible releases, and use the free geographic reference and geometry MCP tools.
Is DaedalMap open source?
The core engine and schemas are open source, so you can run the same resolution yourself. Paid access covers maintenance, QA, packaging, freshness, hosted tools, and support around the maintained data layer.
