Suunto Routeplanner

@kemetter Couple of the issues I’ve noticed when trying to load many routes that I already have on my laptop.

Many longer routes are incomplete when loading, missing beginning or end parts, or both. Suunto App loads the same routes correctly.
Waypoints don’t load from GPX files when waypoints are stored with a route.

When routes are incomplete, it seems routes get trimmed at a waypoint, if there was a waypoint in the GPX file.

@Ecki-D. Thanks for adding the URL

To your comments and requests:

I thought about adding a button/way to drag 3D view, but I have really been fighting against filling the screen with buttons. I think there are too many route planners out there with a zillion configuration options and my aim is to keep this simple. I know the ctrl-mouse isn’t ideal, but I haven’t figured out a way to make a simple UI that won’t add another button.
Starting to show activities open up a whole new box of worms, I have thought about that and it would be doable, but I have decided not to do that at least yet. It will then trigger a load of different things you would want to see from your activity and soon we would have a web based Suunto app. Which I think many would like though…
I’m currently continuing working on route collections as I can notice that people don’t figure it out. A route collection can be created by anyone, currently intended to be among friends, clubs, race organizers to share the link of their own collection, but I am working (as we speak) on making them public in the generic UI if the creator wants to. They are public to anyone anyway but currently requires the correct link. I will try to make them more intuitive.
Segments have been on my todo list, let’s see.
Actually I did implement a flyover feature already earlier, but it’s really difficult to make that look good and work fluently in every situation for every route, so I decided to hide the feature for now and maybe look at it later when there is nothing else to do
Livetracking yes, an even bigger box of worms, but very much requested. However that requires much more support from the whole system, watches, app and backed so will take time to plan that in. But some day…maybe

@Nigel-Taylor-0 Ok, that sounds like a bug. Need to check.

This is how Vienna looks like just searching for the city and clicking the 3D button on MacOS Tahoe 26.2 and Safaria on a Mac Mini M1 2020

On the positive side - 2d and route creation works great and DC Rainmaker also wrote about it: Suunto Route Planner

I don’t see similar with the same configuration. I think this does not have to do with the site code, but something else on your side…

This should match Suunto app quite well, but some GPX files have quite odd content. I would need the original GPX file in question to be able to resolve this.
Waypoints should load if GPX is exported from Suunto app, but from other sites it’s not a standard how they mark user named waypoints.

@kemetter I can confirm that it must be something in my setup, all other devices here work. I have full reset Safari and removed the config folder in “Libraries”, I have no addons, tried private and not private window. I also thought about having issues with my 4K monitor and set resolution tho FullHD - no change. No idea so far

When I find some time I will set up MacOS on an external USB disk and check again …

@kemetter Sounds Great!

Here is one example, which I think I created this in Strava:
Issy Alps 50k.gpx

When I load this in Suunto App it shows all waypoints and the distance is 50 km:

When I load the same GPX file in the routeplanner, no waypoints are shown and the distance is 42 km:
Screenshot 2026-01-30 at 6.32.48 PM.png

It may not be obvious by looking at the screenshots but the missing parts are from the start to the first waypoint and from the last waypoint to the finish. Basically, the route now starts at the top of the first mountain and ends at the top of the last mountain.
I’ve had similar issues with a few more GPX routes.

Also, I should mention that on-route waypoints can also be present in routes that are saved as FIT files. Those can be generated by some route planners such as PlotARoute and are natively supported by Garmin. It would be great if the route planner could load routes in the FIT format too. Also, routes in FIT format can embed turn directions, and some route editors (e.g. PlotARoute) can create those too. It would be awesome is Suunto followed the same standard.

I fixed a bug with GPX loading and that file should load better now. Still some uncertainty about the user waypoints, it seems to load two of them but there apparently should exist four. I will look into that.

Regarding FIT files Routeplanner supports loading them but as they are usually made from exercise logs, there is no turn-by-turn or waypoint support when loading FIT files.

@kemetter many thanks for maintaining and developing this great tool.
Sadly, the area I frequent the most (Dolomites, Italy) have a poor rendering quality, frequently distorted by artefacts that cause the maps to be sometimes completely unreliable
