- The archive flags approximate geocoding, U.S. concentration, truncated summaries, and no independent verification.
Field notes
The archive combines reported dates and coordinates from a geocoded NUFORC dataset compiled by Sigmond Axel (PlanetSig), then exposes them through a D3-rendered map and report log. Visitors can narrow results by five-year periods or reported shape, while larger map markers indicate clusters with more reports. Signal Atlas explicitly notes that summaries may be truncated, locations are approximate, and the dataset is not a live or complete worldwide record.
