What HN said

What people liked

  • Fun and well executed; a kid and parent spent hours with it

    From 2 comments
    • 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!

    • 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!

  • The 'Where it formed' feature is especially liked

  • Soil and Quaternary layers are useful for Midwest terrain

    From 1 comment
    • Very cool. Really like having the soils and quaternary layers for those us in the Midwest without a lot of bedrock exposure.

Objections

  • Unclear whether the geology data is accurate

    From 2 comments
    • 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.

    • 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.

  • Live AR tracking fails on some Android phones

    From 2 comments
    • Whenever I try live view I get "tracking did not start. Try again" on android

    • 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"

    • atleast re-write your subheading "each rock named" most ai smelling shite ever.

    • 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".

  • No web version, so an app install is required

    • 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…

    • Very cool project! I also wonder if a web version is plausible. Are there any specific native app features in it?

  • Support ASTER and Landsat data overlays

    From 2 comments
    • 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…
      lightedman on HN
    • 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…

  • Flip the timeline so past is on the left

    • 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…

Questions

  • Does it work outside the US, such as in the EU?

    From 2 comments
    • This is awesome! Does it work in EU as well? Does this also recognize peaks as well as PeakFinder does?
      vekker on HN
    • US only?

  • Does it work offline?

    From 2 comments
    • 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.
      tomshafer on HN
    • „The map and Live then work with no signal. Fossil finds and Live’s active faults still need a connection.“

  • Does it identify peaks like PeakFinder?
