Do you know where to find the spec for their
data-format?
I can extract some ref-values and gps-locations
but the format of the type of event seems to be
pretty complex.
The site links to tpeg and they have a pdf
that says nearly nothing with links to 2
ISO-specifications that you have to pay for.

The xml-files to not reference a schema of dtd. :/

example:
