These all are pretty cool, but all seem to work based on knowing the
current location, which is is the unknown in Michael's hypothetical
problem. But that said some of the tech behind these tools might be
useful in comparing photo to a potential reference image.
This is a very interesting and
Consider the following hypothetical problem:
Assume we have a good elevation data set for a large region of the earth --
say, an entire mountain range. Now let's say we have a photograph taken
from the ground, the horizon of which shows the profile of a couple of the
mountains in that range.

Hi, I can't remember the project exactly, but I think I saw do
something similar those guys here:

They usually are keen to open source, but I am not sure if that is the

It's definitely in the field of augmented reality research - I had been looking
for the same answer a few years ago and was pointed to a (closed access)
research paper - never did get beyond that restriction :/ I'm very interested
in any results you get to.

Dave, there's a (non open source) augmented reality application for the
iPhone and Android that shows you what peaks you are looking at through your
phone camera.

They say that all the data they use comes from OpenStreetMap (see the FAQ).
Not sure if this is
