[OSM-talk] JOSM Audio Mapping - Technical Issues

[Gregory]

I got a new olympus digital voice recorder for Christmas, which means I have
to use http://code.google.com/p/odvr/ to download the recordings to my
linux/ubuntu computer. Unfortunatly when downloading the wav files the
recorded date gets lost, but a table of the times can be displayed on the
command prompt.

How does JOSM Audio get the date/time of the wav files?
I tried changing the linux files atime and mtime (last accessed/modified
time), but the location marker for the audio does not change. Is it using
the ctime (created time)? I can not change the ctime and it gets set to the
time the files were downloaded off the voice recorder.

I have filled an issue with the odvr downloader, but I want to confirm that
it is the ctime that needs to be right for JOSM. I was recording ~2sec
comments as I passed a location, so I have a trip with 60 recordings waiting
to be mapped.

My final idea is maybe I could make a JOSM plugin (now I've learnt some
Java) that takes a fixed-width txt table of time stamps and names, and match
the times to an open gpx file to create waypoints. This would mean I have to
open audio files outside of josm, but at least I would know where they were
recorded. Such a plugin may help people with other media problems, ao I
wonder has something along those lines already been done?

I've been told audio mapping is more amazing than photo mapping, and it
would be ideal cycling in these cold winter months. Sadly it's not going to
well yet, so I hope to get this sorted.
