Hi,

I am using a GARMIN Oregon 300 and I am seeing some strange behaviour when exporting a route from grouph to the unit.

I create a simple route with a waypoint and export it the unit as a track (I prefer to use tracks due to some Garmin issues with display of routes). When I view the track on the Oregon the waypoint is not visible. Neither can it be seen on the waypoint manager of the oregon unit.

When I look at the gpx file created on the unit I see the waypoint defined as a trackpoint (defined by a child element type=Waypoint). I had expected to see the waypoint listed as a true gpx 'wpt' element. Is this why it isn't showing up?
Can anyone comment?

Thanks
Neil

Hi Neil,

In a GPX file, 'trkpt', 'rtept' and 'wpt' all represent individual points in space, and all follow the same format. The only difference is that trkpt and rtept form part of an ordered route or track segment, whereas waypoints are essentially un-ordered.

What grough route calls a waypoint, isn't the same as what the GPX schema calls a waypoint. grough route uses waypoints to define the start and end of a leg, or a point at which the user changes direction, speed, needs to navigate a junction etc - essentially just important points on the route. All the points between these are just known as 'points'.

When you export a route, only a route or track is included in the file, with each point included as part of the route or track in the correct order. It doesn't any extra entries outside of the route or track.

With a Garmin device, your waypoints' names would show up on the map and when the pin was tapped, but I appreciate the pins for other points can be frustratingly large. Tracks don't have any of these features.

Hopefully that makes some sort of sense.

Hi Luke,

Thanks for clarifying - I do understand what you are saying - but I wouldn't say it makes sense...

If the gpx format is the interface between grouph and Garmin (or any other gps) then I'd expect grouph to conform to that interface.

A gpx file can contain both trk and wpt elements (as siblings) but I guess you are saying this is not the way grouph works.

Unfortunately I don't get 'pins' in tracks, only in routes so my 'grough waypoints' are lost.

Ho hum. Thanks for replying.

It's disappointing that Luke has not come back on this one!
