GPX export does not have correct altitudes in rtept - ele Element #1053

Closed bm98 closed 9 months ago

bm98 commented 9 months ago

Issue found with LNM V 2.8.12 64-bit rev af004428 Win10 64bit

When exporting a GPX (Garmin Exchange Format) with MultiExport The Route - - Items do not carry the correct altitude except for the Airports all others seem to have the Cruise Alt

the Track seems to report with a profile but I cannot derive the unit from the numbers...

See attached files: LNMPlan GPX export HTML export which is correct as far as I can see

IFR Galeao-Antonio C Jobim Intl (SBGL) to Congonhas Intl (SBSP).zip

It would be helpful to have the correct altitudes reported in the GPX export Thank you :)

Thank you for the files and the description! :+1:

I can confirm this. The track has the correct flown altitude (elements "ele") but the route does not. The units are always meters according to Wikipedia - GPS Exchange Format - Units.

I'll change the route to contain the altitudes from the calculated profile but will keep the actually flown altitude in the track. Hope this makes sense.

Thank you - I am looking mostly for the route (used as Plan) leaving the track as flown profile makes perfectly sense.. and thanks for confirming meters. I don't remember having flown this route with LNM so that examples track with dates of 1970 may be artificial? Trk seems not related to the route in the example (lat, lons don't match at all) But I might have messed up here - don't know.

The time is simulator UTC. Means it is whatever time you've set in the sim. Exporting here gives me the correct sim time and not epoch.

You have to clear the track before flying (File -> Reset all for new flight). Otherwise you'll get a track from the previous flight(s).

A logbook entry also gets a track assigned which starts at takeoff and ends at touchdown. You can save this from the logbook table context menu Files ... This one does not contain previous flights.
