My camera records GPS stamps in pictures. It does this without regard for the current validity of the GPS reading; it just marks invalid records. This is good most of the time.
Given a set of pictures taken in sequence, it should be possible to use heuristics to infer more accurate locations for some pictures, and to remove location data from pictures without any reasonable confidence in their location.
This project is an attempt to implement such semantics. It is currently a mess of scripting I'm writing as I look through data to see whether there's anything useful to do here, or whether I ought to just drop all the invalid fixes because there is too much noise.
It is written in Python, works on at least Python 2.6, requires python-plumbum, python-dateutil, and exiftool installed. The test suite requires the xz executable, testutils, and coverage as well.
