When I Import GPS Assets from a GPX file containing a Track with Track-Segments, the result is a simple track. Track-Segments are lost and the track-end-points are connected.

I need the option to create a User Map(Custom Path), then have the additional option under Import Path to also select the GPX file-type as I can do with KMZ.
This should support track-segments as does reading a KMZ file.

Still have not figured this out.

In a nutshell.
I have a multi-track-segmented track built in Reefmaster as a Custom Path Map. After writing out the Map as a GPX file all is well except I cannot figure out how to bring this GPX file back into RM and into another Map. If I use Import GPS Assets to bring the track in this GPX back into RM as a track, then move the track into another Map, then it is corrupted and end-points are connected which is not correct.

This isn't possible at the moment I'm afraid. RM doesn't write segmented GPX files, and it imports segmentd GPX files as a single track - it has always been this way. The plan is to update this to take segments into account. The only segmented track files that are written are in the Humminbird HT format, to put as many tracks/contours as possible into a single track slot. For now the only option would be to export the tracks individually (i.e. not as part of a user map).

I'm confused now.

I've merged individual tracks into a User Map. I've written the User Map out as a Reefmaster GPX, then imported into Lowrance HDS & Humminbird units just fine as a segmented track.

Seems many PC programs fail to totally support segmented tracks somewhere in their code-paths. HumminbirdPC, Lowrance's Insight Planner, ExpertGPS, etc.

It would be nice to directly or indirectly import a existing segmented track back into a User Map. Either to import it as a track, then move it to the UM or directly import it as a KML.

I agree - although issues can then arise where some other programs see a segmented GPX track as a single track. The GPX format does allow for any number of separate tracks to be stored in a single file, so segments aren't really necessary for most situations. The one thing that they are very useful for is fitting multiple tracks into a single Humminbird HT file track slot, which makes editing track styles easier and allows you to store many more tracks on the unit. Do you have any other use-cases in mind?

Submerged creek and river tracks can contain hundreds of track-segments which make them much easier to build and maintain.
Same for boat-runs for running in semi-timbered lake areas.

Would be nice if RM supported importing GPX assests with track-segments, then supported same track-segmentation when moved to a User Map.
And also supported track-segmentation importing into Custom Paths similar to importing a KML.

I've been playing with this some and testing track-segmentation in ReefMaster. It is difficult to get track-segmentation from sonar units in .HT or GPX exported formats back into ReefMaster without the track-segmentation becoming corrupted. By corruption, I mean the track-segments are merged with the track-end-points connected. (And on a side-subject, RM support of USRv4 or USRv5 would be nice).

RM supports track-segmentation when writing .HT, GPX and KML/KMZ files. RM only supports track-segmentation when reading KML/KMZ files under Custom Paths Import.

Problem is transferring track-segmentation from sonar units back into RM since RM does not have the read support in .HT, GPX, USRv4/USRv5 formats.

Only workaround I've found is to run GPX exports through Google Earth or RideLeader, then create the KML/KMZ for RM.

Any other thoughts or workarounds? Can RM support directly reading sonar units exports with track-segmentation and the transfer into User Maps?
This is often need for track changes and maintenance. Also I worry about track accuracy with the extra conversions.

I'll look into this some more and see if we can include an update in the next version. It wouldn't be hard to create a track per segment, but this might result in a lot of tracks being generated - I don't think we could fit "multi segments" into the current track model. Alternatively, if this is just going to be for use in user maps, then import direct to a UM could be added for .HT, and GPX could import as segments there by default. Would that be sufficient? The issue there is that individual depths would be lost within the track.

Yes, if I understand you correctly.

I have track-segmented track as a User Map Custom Path.

• Ability to import a Lowrance or Humminbird exported track as another track-segment. GPX and .HT import would do this.
• Ability to import a complete track-segmented track. GPX and .HT import would do this.
• Ability to import USRv4 or USRv5 would be extra nice also.

I don't need depths as tracks are submerged roadbeds, boat-lanes and creeks.

A related question:
When you choose to edit a existing User Map, can RM determine what Group Type(Isobath, Hardness, . . . Custom path) that UM is? I have to manually select Custom path on existing UM's.

Matt,
Thanks in advance for coding RM to allow .HT & GPX files to be directly imported into Custom Paths.

But, one more minor request is could you also have RM display the Total Number of Track-Points in a Custom Path? Sure would save me a lot of additions. . .
Thank in advance again.
