        Like a train station?

        Honestly, I’d be fine with a fast travel sign post as long as worked as intended.

      Honestly, I’d rather have them remove all timed quests. Those are the ones that suck the enjoyment out of my travel experiences.

    Mobile OSM is a bit like that when it hasn’t downloaded the tiles for the regions you don’t usually go to.

    Kind of terrifying since I use maps pretty much exclusively for places I haven’t been to yet, so I’m not totally unfamiliar when I go there

    I’d love this, but like Hero’s Path so it knows everywhere you’ve ever been, like the time I somehow made it back to Merton from wherever the night bus dropped me off drunk that time.

      same,

      would be nice to see where you have exploded,

      wonder if google has an API to get that info from your location history and make a web app that shows you how much you’ve explored

    Had that (for OpenStreetMap) on my long list of project ideas, including quests you could take to some random monuments. Maybe one day.

      There is an app of fdroid and google play called street complete. Its basically quests to fill in local missing data on openstreet map

        You have reminded me that StreetComplete exists. I used to use it a while back, but for the last few years, I lived in an area that was already pretty thoroughly mapped. However, I would wager that where I live now is more sparsely documented; I’ve only recently moved here, and StreetComplete could be a nice way to become more settled.

          Street complete is great for learning a new area, and there are always things to update. A business changed or whatever

      Dawarich has support for this. Be aware it is under very active development and has semi-frequent breaking changes though (No data loss, just manual steps to upgrade).

      For example, here’s my recent trip to Austin for the Counter-Strike Major:

      And with regular routing:

      It technically works offline because you can record your location and load it afterwards, but I use it by ingesting my location that is tracked by Home Assistant

      Fog Of World really isn’t so bad. For some reason it makes you back up to Dropbox or Onedrive but I suppose you could just not hook them up and keep it all offline. It’s better than handing your data to some random company, I doubt Dropbox/Microsoft are going to analyze some random app’s data like this to track you.

          I didn’t say you need internet connection. But you do need a satellite uplink. So, I wouldn’t call that offline. Clearly, many others do so maybe I’m wrong.

            Nah, GPS isn’t a two-way thing. There’s no way for the GPS system to track devices.

            Your phone figures out where itself is using the satellites as markers, the phone doesn’t emit any signals for this. It’s offline.

            Basically the way it works is GPS satellites broadcast a very accurate time signal, (and occasionally data about the satellites exact orbit). Your phone sees this and uses signals from at least four satellites to find it’s location. It does this by measuring the delay in the signal between them. (Due to the speed of light, each signal will be delayed slightly). Knowing the delay in the signal you will know how far away you are from the satellite, and knowing the exact time along with it’s orbit info will tell you where exactly the satellite is. But knowing that you’re 13,000mi away from a satellite doesn’t help much. But then if you look at the other signals you can see you’re 16,000mi from another satellite, and so on which when you use 4 satellites will leave you with one possible spot you can be.

              Jaw drop moment for me… I did not know that.

              I’d have probably expected that your phone automatically sends the device ID, but that’s of course not necessary.

            You’re inferring a tone where there isn’t one.

            I was asking if this is a common misconception as I had assumed the userbase here was generally pretty tech savvy, and confusing GPS with internet seemed particularly strange.

          That’s what I thought. I figured things like the original garmins had a quantity unlimited but very narrowly usable data plan, like old kindles. I did know that gps was invented before the internet was widespread, but I figured that today it was like fax machines, where the vast majority don’t actually have a landline connection anymore and use the internet instead.

          Based on this comment section, I gathered that it was something else, but still didn’t expect it to be fucking radio.

              I don’t feel dumb, lol. It’s very far from my areas of interest. I’m sure I’ve got more incorrect opinions about all sorts of fields I don’t think much about. The important thing is, I know how to research.

        GPS via Satellites is offline! All satellites do(*) is transmit down to the Earth’s surface. Those signals will exist whether there’s a receiver there (ie. Your phone) or not. A GPS works by detecting those signals (ideally it will get at least 4 different ones for best accuracy) and calculating your location by triangulating it based on the signals (**). No upload on your end is required, it’s very similar to how radio works.

        (*) As in, all they need to do is this. Specific satellites have different features for different jobs and specs. But all they have to do to make GPS work is transmit.

        (**) I mean “triangulate” as in the principle of triangulation, as in being able to determine the geography of a point via the topology of it to other known points. It’s not actual triangulation with satellites because a fourth one acts as a correction factor – we’re dealing with signals going the speed of light after all. But that isn’t important for whether or not GPS needs to upload anything to work – it doesn’t.
