%description
ShadowFinder, from Bellingcat, takes the height of an object, the length of
its shadow and the date and time a photo was taken, and maps everywhere on
Earth where the sun stood at the matching angle. It narrows down where an
image could have been taken; it can also start from a known sun altitude.
