That's no excuse for disbelieving GPS for extended periods of time. Google Maps gets it right: it tried to keep you on road, but only for a few tens of seconds

That's no excuse for disbelieving GPS for extended periods of time. Google Maps gets it right: it tried to keep you on road, but only for a few tens of seconds. After that, if you are in the middle of uncharted territory, it'll show the marker there. (This is probably because Google Maps can be used for walking/biking too)

>(This is probably because Google Maps can be used for walking/biking too) Please don't do that. The map is simply not good enough and does not have enough context (road quality, terrain, trail difficulty) for anything but very causal activity. Even then I highly recommend to use a proper map, electronic or paper.

  yeah I'm not gonna open some paid trail map or buy a paper map so I can walk across my local city park and give my friends a pin to find me...

    I've found Organic Maps to be better than any paid app for hiking (and I've tried a bunch) for what it's worth

      For anything other than driving Organic Maps (iOS) or OSMand (Android) are the very best.

      I find Gaia Maps even better for the boonies. It has a lot more map data accessible and you can even overlay National Park Service maps, land ownership, accurate cell service grids, mountain biking trails, weather conditions and things like that. Disclaimer: Just because you see a route on a map, digital or paper, does not mean it is passable today. Or it may be passable but at an extremely arduous pace.

  We used the walking directions for dual sport motorcycles once. It was pretty nice. We did have a few places where it became sketchy. Those and maybe more places would be sketchy for walking too. Not that google maps could do much about it. Terrain is a living thing. These were mostly huge cracks in the earth due to rain water.

  Trail? Terrain? I use it for walking for 10-20mins around a (mostly flat) city and I expect that’s what 90% of people use it for, the comment didn’t mention hiking

  It depends what you are doing but for hill walking in Italy I found the footpathapp.com app good. There are no decent paper maps in the area I go and Google maps are also rubbish for local paths but the app kind of draws in paths based on satellite images I think and you can draw on it to mark the ones you've been on.

Well, when I’m driving in Kyiv, and there is an air raid alert, usually my car navigation starts to derp, and after a few minutes it thinks that it’s suddenly in Lima, Peru. Not that I mind too much, I know how to get around without navigation.

  It does teleport to Peru but it also fast-forwards time to about a year into the future, which caused my car to think its overdue for that oil change. It even synced that back to the headquarters and I got an email asking me to take it to service.. (and arriving there on the wrong side of the Dnieper, I just decided to wait it out) Wish we could put it into a manual mode where you just reset it's position once and then it updates based on wheel encoders & snapping to roads.

  GPS jamming for incoming drones?

- circuit10 11mo ago
  They’re saying that not prioritising (disbelieving) GPS data is bad, hence there’s no excuse for it So that’s the same thing you’re saying
  - hnlmorg 11mo ago
    Yes, I know. And saying that as a rebuttal to a comment where I’d said the same. Hence my reply ;)

  The technology should be resilient against GPS spoofing. If it “knows” it never left the mountain road, it’s not crazy to design it to reject an anomalous GPS signal, which might be wrong or tampered with.
  - hnlmorg 11mo ago
    I think the likelihood of that happening is significantly less than the likelihood that a car took a new road or other path not show in the cars mapping data.

Well you can also drive off road too.
