The Locus gpx (rte)route export.

Can it be offered in a more valuable way ?
Optimise by exporting as standard compact route.
Contains only start & shaping & Via and Finish as route points.

Picture. Locus navtrack. The coloured sections exported as the routepoints.

gpx file in the attachment. (Track + route)

Notice the fast Mapsource route calculation.
Compare with the reference track overlay.

>Who actually uses the current Locus gpx export?
I only use non-RTE format, so happy for you to ignore or discard my thoughts below

>Contains only start & shaping & Via and Finish as route points.
but dangerous - without any knowledge of the routing profile, on import the viewer (most likely Locus) could (mostly likely) create a subtly or completely different (unwanted) route/ track. Any setting like this should not be the default.

I know this because my old Garmin eTrex would generate completely different (unwanted) route/ track when only start/ finish point was in the GPX file (exported from RWGPS). As a new GPS user it was very confusing.

So there needs to be a clear warning on the danger of this style of export. Maybe the addition of a (?) icon/ button alongside the checkbox to explain the ramifications.

Hello Willy, Andrew,

GPX RTE export was made a long time ago with a single purpose in mind: support for older Garmin devices that were unable to read TKR GPX routes. I do not measure how much this feature is still used to be true, but it works well as is. I simply think there is no need for improvements. Only what I may think about, is to completely remove this option.

I miss in both posts the main info for me: why this change? What should be the benefit? Are you using in any Garmin devices this GPX RTE format?

I don't suggest any changes @menion. I was purely debating pros &  cons of the original post & my experience (pitfalls for young players) from years ago with an old Garmin eTrex before moving to smart(er) devices.

Oki, understand. I'll measure how many users use this feature and consider its complete removal. Thanks.

I like the proposal of 0709:

'Can it be offered in a more valuable way ?
Optimise by exporting as standard compact route.
Contains only start & shaping & Via and Finish as route points.'
