    Soil data seems to sharply follow boundaries of many countries. This shows how fragmented this data is. This is in contrast with eg. orography which one can just get from satellites.

    This is really well done! My 9-year-old and I have been going down the rabbit hole for the last 2 hours. We simply love the ‘Where it formed’ feature. Great job!

      wow this is so delightful to read!! glad you two are enjoying it!

    Very well done. The animation of plate movements give me a real sense of vertigo! Earth is old. o__O

    For me at least, it would feel more intuitive to have the distant past on the left and the current date on the right. I'd also love an option to keep the current location centered while manually dragging the slider.

    EDIT: Also, could optionally overlay lat/lon lines to help anchor the globe as it rotates? It's hard to understand the plate movements relative to the Earth.

      oh interesting yeah I was trying to keep the time direction consistent with the squiggle graphic in the main sheet, but I can see how it would read backwards! Maybe I should flip them in both spots.

    Is there a web version? I don't like to install apps if avoidable.

    When the page loads, it shows a blinking animation [1]. I didn't realize it was a loading an interactive background example. Perhaps load a default photo of the grand canyons and add a clock or something until the full version loads.

    [1] In my phone in the subway, not a very good WiFi nearby.

      been thinking of trying a web version! the AR stuff might be tough (I'm relying on ARcore/ARKit a lot) but I think all the pieces are there to make it possible. Good call on the image fallback! The 3d demos are probably heavier than they should be for a landing page hero...

    This is timely. I am on my way to the Grand Canyon today. Will install and give it a go with my son. I think he will be excited.
    • headsupernova 17 hours ago
      oh man a screenshot of the live view on the Canyon would make my day!! please send one over (shane @t flyovercountry.app). Fingers crossed it works for you!
      • hsparikh 8 hours ago
        Alas - heavy rainfall and flash floods across northern and central AZ today, so we had to postpone. Will let you know.

    This is awesome! Does it work in EU as well?

    Does this also recognize peaks as well as PeakFinder does?

  • nsilvestri 18 hours ago
    Very cool. Does this mean any chance AR features are coming to Flyover Country? I've used that app for years, but matching what I see onto the map is the trickiest part.
    • headsupernova 17 hours ago
      They're in there already (as of a month or so ago)! I'm really excited about AR in Flyover. Especially interested to hear your feedback on the new version having used it for so long!

    Great work! One of those apps that scratch the itch!
  • StepWeiwu 11 hours ago
    Super cool, congrats! I've played around with the android app, works great and it's really interesting!

    It's a cool idea but how do you know whether it's accurate? Couldn't it just be making stuff up? Laymen consumers would have no way to tell the difference.
    • pragmatick 4 hours ago
      It pulls the data from https://macrostrat.org/ and "just" determines where you are and does the AR overlay. So I guess it depends if you trust their data.

    This is very cool! Great use of augmented reality. Now have a narration mode that gives you LLM-based Roadside Geology explanations of what you’re seeing as you drive.
    • headsupernova 20 hours ago
      Somebody else is working on exactly that! check out Backseat Geologist
  • thingfyi 16 hours ago
    Very cool project! I also wonder if a web version is plausible. Are there any specific native app features in it?
    • headsupernova 14 hours ago
      the AR stuff leans heavily on ARkit and ARCore APIs but I think similar things are possible with web apis.
  • ballen 20 hours ago
    Very cool. Really like having the soils and quaternary layers for those us in the Midwest without a lot of bedrock exposure.
    • headsupernova 20 hours ago
      there are so many cool glacial stories (and more!) in the midwest! I'm trying to sort out how to better tell them in the app based on the available data.
  • chamomeal 23 hours ago
    No WAY I have wanted this exact thing all for years!!! I am so stoked to try this out later. This is so sick.

    Got the test flight version installed no problem!

    • headsupernova 21 hours ago
      send some screenshots my way when you try it outside!
  • assimpleaspossi 21 hours ago
    I don't see it on the Play Store for my Pixel 11. There are two marked "Outcrop" but not by these people.

    Whenever I try live view I get "tracking did not start. Try again" on android
    • headsupernova 22 hours ago
      oof sorry, thanks for reporting! I've got a limited set of phones to test on so this is super helpful. What is your device/android version?
      • RobotToaster 20 hours ago
        It's a old Doogee v31gt running android 13

        Edit: It looks to be my phone, I just tried it again and it says "This phone can't do the motion tracking Live needs"

  • headsupernova 19 hours ago
    Shameless other project plug: if you have a flight coming up and are a window seat fan please try out https://flyovercountry.app ! it has a similar augmented reality view so you can figure out what you're seeing out the airplane window (and a bunch of other fun features)
  • lightedman 22 hours ago
    This would be insanely awesome if I could add a data layer or two atop the geologic unit map. This combined with processed ASTER and LANDAST data overlaying the geologic units would make surficial mineralogy so much more exciting when you're out in the field.
    • headsupernova 21 hours ago
      hadn't seen ASTER data before this! looks like some really cool data! I'll look into adding it for sure
      • lightedman 8 hours ago
        The processed stuff is what you want, northwest and southwest, AA12. Best thing to do is knock out the dead data layers (I think those were 48-50) and knock out I think band 14 (green vegetation layer) so all you get are the properly-identified signals. Ditto LANDSAT 8 (iron sulfate processed data.)

        I suggest making it possible to support and import these sorts of data layers instead of including them as they do get very, very large. Leave it up to the user to slap them in and toggle them on/off on their own.

        This would make it an instantly-valuable tool for professional, hobbyist, and studying geologists.

        EDIT: https://imgur.com/a/fYf83hw Like this sort of processed data overlaid on top of the geologic units (with legend) would be so insanely helpful.

    This is very interesting!! I just pointed at a landscape from a high ground and it said this river was formed around 460million years ago! Which it seems is that old in earth’s life!
    • headsupernova 20 hours ago
      it's more that the rocks underlying the river are that old! I wonder how I can make this distinction more clear.
  • hailwood1965 14 hours ago
    I hope to one day try it. I'm an hour south of Mpls. It would be interesting to use it on one of those super-deep gravel pits in rural Goodhue where one can see ten stories of earth. Good luck.
  • xaviermts 14 hours ago
    US only?
  • Aeroi 19 hours ago
    atleast re-write your subheading "each rock named" most ai smelling shite ever.
    • seabass 14 hours ago
      It's always so disappointing. This looks genuinely cool, soured by all the little ai artifacts that get hard to look past, like "the circle names what it rests on".
      • headsupernova 13 hours ago
        please keep listing these examples out it's genuinely helpful to hear what rings poorly to people. I've been focused on the app build in my spare time and don't have a ton of experience with marketing so the copy is def a relative afterthought and leans sloppy for sure.
        • jcattle 3 hours ago
          Just to add some positivity: I love the demo on the webpage where you can drag the phone around the panoramas. So fun!
        • throwaway219450 8 hours ago
          If you build anything with AI that is meant to be read by anyone other than AI, assume you need to review and rewrite all the copy. No need to be a marketing person, just read what the models produce and question if it’s understandable. The bar is frankly pretty low.

          “Names” is a particularly obvious one. “Pick a rock and the land keeps it in color, the rest gone grey.”. And a big bugbear of mine are sentences like this “The map lights the places it’s mapped” - why is the map the actor in the sentence? Just put: “Places are highlighted on the map”.

      fair enough

    Neat idea. Does it work offline? Up north there's often no signal, and I'd guess phone compass drift near steel bridges or cliffs would throw the overlay off too.
