Nick,
if a building, rock or similar is shading half of the sky you can record the
same trail at 30 diferent times and together with the DOP you know which
recording is useless and which has a chance to be accurate. Togeteher with the
velocity and heading you have a chance to narrow the corrido

If you use a GPS mouse with built in memory you can record quite a lot for a
long time. That solution has a few more advantages compared to a Garmin:

After conversations with TomH and others, I have finally gotten around
to rewriting the GPX importer in C.
Attached is r14 of my code, and I believe it to be *ALMOST*

In essence, it functions equivalently to the ruby importer, however it
