gipfel helps to find the names of mountains or points of interest
on a picture.
It uses a database containing names and GPS data. With the given viewpoint
(the point from which the picture was taken) and two known mountains
on the picture, gipfel can compute all parameters needed to compute the
positions of other mountains on the picture.
gipfel can also be used to play around with the parameters manually.
You can think of gipfel as a georeferencing software for arbitrary images
(not only satellite images or maps).
gipfel also has an image stitching mode, which allows to generate panorama
images from multiple images that have been referenced with gipfel.
