Basically ATM Viking does not support newer tags in the GPX 1.1 standard, especially for the Extension style ones.
See: https://sourceforge.net/p/viking/feature-requests/96/ It would be nice to support the common speed, cadence, heart rate data, temperature but as yet no one has done it. I did start on using GPX 1.1 but only got as far as supporting the 'DisplayColor' extension. So some open questions are: 1. When saving to a GPX file do you: a) If from a existing GPX file save in whatever version it was based on? and/or for any thing: b) Ask which version to save in each time? c) Default to 1.0 or 1.1 as set in may be in the advanced options somewhere. 2. Do you want to try to do something useful with this extra HR, cadence data etc... when reading in a file. a) Extend the track point dialogs to show it somehow and/or b) Have some useful graphs of this data. [Obviously even more coding work required]. -- Be Seeing You - Rob.

After a little more investigation, I find that these extensions are defined in https://www8.garmin.com/xmlschemas/TrackPointExtensionv2.xsd as an extension using http://www.topografix.com/GPX/1/1/gpx.xsd Viking seems to know about <speed> which is not surprisng since it is in version 1.0 of the gpx.xsd. I don't know enough about this area to know whether it should fetch and parse https://www8.garmin.com/xmlschemas/TrackPointExtensionv2.xsd each time it sees such extensions which sounds expensive, or have have common extended tags built in. Perhaps there are other extended tags for speed other than Garmin's? Also in the Garmin xsd are extensions for course and bearing: I am not sure whether those are relevant for Viking. ael _______________________________________________ Viking-devel mailing list Viking-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/viking-devel Viking home page: http://viking.sf.net/ _______________________________________________ Viking-devel mailing list Viking-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/viking-devel Viking home page: http://viking.sf.net/
