Fw: Re: Fw: Re: [Openstreetmap] GPS point submission format

slightly arcane format, but there you are. gpsbabel definitely
supports this. as for post-facto DGPS correction it's a good idea; the
nearest DPGS server to london that i know of it in italy though. we'd
toyed with the idea of having a whip-round to set one up in
limehouse...

GPX does support altitude, for both track points and waypoints.
