I’m in the process of trying to plan the Transcontinental Race. Google Maps is of course my first port of call—I particularly like the feature which allows you to ‘drive’ along a selected route. Unfortunately, with the new version you can no longer export a selected route to your Garmin GPS device. However, I’ve worked out a way of doing so …
The first step is to get the route in Google Maps. I prefer to use the ‘Walking’ route over the driving route in the (probably vain) hope it takes less busy roads. I then manually adjust the route until it’s sensible.
You then click on the ‘link’ button in the left toolbar and are given the window below:
Right click on the top line and select Copy.
You need to download the program ‘TyretoTravel’ from www.tyretotravel.com.
Once the program is started, select File|Import from Web Site. In the window that opens put the cursor, remove the ‘http://’, and go CTRL V to paste in the copied information from Google Maps.
Click the Import button (bottom right), and select ‘Route tracks’. Select OK.
Your route will be imported as a series of Waypoints.
You can save the file as a .GPX or send it to your Garmin using the Garmin|Copy to Garmin menu option.
The .GPX file needs to be in the folder ‘NewFiles’ on the Garmin Edge 800 so I manually put it there. I also put on the SD card in the same location as a backup.
The GPX file is only the x-y co-ordinates, but what about elevations? Fortunately, there is a fix for that as well. You go to: http://www.gpsvisualizer.com/elevation and upload your GPX file. You then select Convert & add elevation. This creates a new GPX file with the elevation data estimated from terrain models.
This is the estimated profile. Considering that the the elevation of Mt. Lovcen in Montengro is something over 1500 metres we aren’t too far off. Got a few hills to cross on the way … good thing I have time to do some route planning!
