Malcopoplo, here’s an example of what I mean about Kurviger mucking around with imported Garmin routes. It’s not Kurviger’s fault, it’s just made that way. To be fair I might have been able to tamper about with the way the route was imported but I thought I’d use the way most people probably do it. In this example I have used route 01, which looks like this:
I exported the route into Kurviger, using my iMac:
You can see that the Kurviger route is significantly different and something truly bizarre has happened in the east south east corner, where an entire loop has appeared.
Switching to the motorway option (ie switching the Kurviger algorithm away from an over emphasis on curves) improves things a lot:
I then asked my Mac to create a track from the route, which it did perfectly, replicating it inch by inch.
The perceived wisdom is that the conversion of a track into a route in third party software is always perfect. This is not always true, as we can see in the last screen shot. Yes, it is near enough right but you can see where the blue Kurviger route does deviate from the red track. This might not matter too much but would be very annoying if you were meant to meet someone (or stop at a hotel) on a road covered by the track, only to sail past on a totally different road, following the blue line generated by Kurviger. You can see where the Kurviger blue line deviates from the red line of the track in the top north corner. I think I know why Kurviger did it. It’s all down to algorithms. By zooming in I can see that the Garmin track follows quite a small road, that runs parallel to a larger road. The least curvy Kurviger algorithm wants to head towards motorways (or at least not exclude them) so it favours the larger road, understandably.
In short:
1. Stick to Garmin, wherever possible. It is not the monster everyone says it is. I couldn’t create 30 routes in pretty short order if it were.
2. Check things before you set out, no matter what software you use.
3. Use third party routing software that does not have any fancy algorithms attached to it. In other words, one that will just recreate things perfectly.
4. Get good at editing!
