A WORKING DIRECTORYReferences you can inspect.
This directory reflects the mappings in our checked source snapshots. Unknown coordinates, time zones and datums remain explicitly unrecorded. A beach reference does not represent every point on that beach.
Automated source checks are separate from human editorial approval. The original resources still await human signoff. Source-specific reuse terms are being inventoried; this download does not grant rights to agency or third-party content.
