ShadowFinder
Bellingcat tool that takes an object's height, its shadow length and a date/time, and plots every location on Earth where that shadow ratio was possible.

field note
The reverse of SunCalc. Use it when you know when the photo was taken (e.g. from upload metadata) but not where. The output band narrows the latitude dramatically.
