Show HN: Point your camera at a landscape to learn about its geology
233 points - last Thursday at 3:22 PM
I've been working on a fun little app that paints geologic maps over landscapes using augmented reality. You can use it to identify what the mapped rocks are, read descriptions about them, and view the earth as it looked when they formed by turning back the continent positions. It spun out of some augmented reality work I was doing on my other side project app - Flyover Country, which tells you about the view from the airplane window.
I'm in Minnesota, so i haven't had a chance to test it on a huge amount of terrain (the best I've found is the Mississippi River gorge in the twin cities... I need a trip up north), so anyone that's somewhere with some more bumps: please help!).
It's stuck in the Apple review queue, but it's up on testflight for anyone interested. Google approved it quickly and it's fully out on android (links to both on the marketing site).
edit: got a report that testflight was asking for an install code. Seems like a testflight app issue, but dismissing it and installing as normal seems to work!
I wonder what it would take to be able to add a "somewhere else like this" feature that shows you other places in the world that have the same toes of rocks.
For example: maybe the granite of the Appalachian is geologically contiguous with rocks in far east Canada or even Iceland?
Or, if I was a wine guy, maybe I want to find a part of the world where the rock is flint and limestone that is like Sancerre, but isn't in France.

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.

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.

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!

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.

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.

This is awesome! Does it work in EU as well?
Does this also recognize peaks as well as PeakFinder does?

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.

Great work! One of those apps that scratch the itch!

Super cool, congrats! I've played around with the android app, works great and it's really interesting!

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.

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

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.

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

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!

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

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)

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.

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!

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.

US only?

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

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.
