====================
kml.py
------
Provides a fuinction which extracts Track information from KML files. Hasn't been tested on a variety of KML files.
Requirements:
* [lxml](http://lxml.de/)
dtw.py
------
A Python implementation of the multi-dimensional DTW algorithm with Manhattan distance. It's very slow.
Commented is a 1D DTW reference for the mlpy implementation, which is faster, but does not work on coordinates.
Usage:
* ``python dtw.py``
Grabs the KML files from ``tracks/`` and displays the distance matrix for each pair of tracks.
Optional requirements:
* [mlpy](http://mlpy.sourceforge.net/)
pdfannot.py
-----------
Extracts basic annotation information from a PDF file. Uses the python poppler wrapper.
Highly extendable :).
Requirements:
* [poppler-python](https://launchpad.net/poppler-python) (0.12+, )
Usage:
``python pdfannot.py ABSOLUTE_PATH``
