Sounds like a combination of 'can it be geocoded?' and 'is their location precise enough?' There is some progress on resolving human-written locations in cities ( https://www.danvk.org/2026/03/08/oldnyc-updates.html ) but I imagine once you lose reference points, '100 feet into Golden Gate Park...' would be interpretable but not possible to fix to one point.

You're absolutely right. Highways are a little better since they have mile markers, but once you get into a nature preserve you're dealing with a whole bunch of "If you pass the pond with the cattails on your left, you've gone too far." Fishermen, it turned out, LOVED sending coordinates for stuff they saw so long as their fishing spot wasn't nearby.

Cool article btw!
