I use the app PeakFinder all the time and it’s incredible for determining what mountain is what when you’re on the go!

I used to use PeakFinder, but then it was withdrawn and the free version disabled. Now it costs $5.

Among the best 5$ I've ever spent.

This is a well polished app, which has non-trivial technical solutions (the AR view works very well and must not have been so simple to implement reliability on a miriad of different android devices).

5 dollars! C'mon.

I’d like to be able to determine the location of a landscape photo. Should be able to calculate the panorama for 5x5 mile regions of earth, and use some matching algorithms to find the closest profile to my picture. I thought about this when watching geowizard: https://youtu.be/0ZbmYh9QZgA

I mentioned GeoImageViewer in a reply above. It contains several algorithms to determine the location of a landscape photo given some control points selected on a map. It is also able to determine lens parameters (fov, distortions,...). https://hdersch.github.io/

If you thing this is cool, also check out CalTopo (my favorite mapping software for backpacking): - https://caltopo.com/map.html#ll=40.10094,-105.61557&z=15&b=m... - Right click and select "Simulated View" - Change to "WireImagery" in the upper right

wow this is cool!

but somehow the wireimagery setting doesn't work for any of the locations I've tried. it does work for the one you linked...

Edit: oh... picked a random location in the USA instead and there it works. So... no Europe? what's up with that?

Edit 2: also no south america apparently.
