I would like to track a route from Lands End to John O'Groats. My intension is to drive the route and map it using a laptop and a GPS receiver then export the GPX file to a garmin and follow it on a bike.
As the cycle will not be a holiday ride I will use main roads so need the route mapping needs to be 100% accurate especially riding through cities. I have tried mapping this using online websites but have found they keep dropping points and as so are not 100% accurate. The last thing I need is for a sharp left then right to be vague route through a building!
Could anyone recommend software or even a device which will do what I'm after?
100% mapping will never be possible. 100% accuracy of the gps will never be possible. The best you can hope for will be a good gps receiver with a good external antenna and the latest maps you can find for it.
... OziExplorer and I see it will do a maximum of 10000 points. Unfortunately Im already over that number by using online sites.
Sorry about the late response but I've only just joined this site.
As with any other navigation system, the accuracy is only as good as the mapping data you have, so provided you use the latest maps available to you OziExplorer is as accurate as anything else. Your problem with the limit on the number of points is quite easily overcome by splitting your route into multiple files and loading them as and when required.
if you have a garmin gps, install mapsource and map on your pc, then download garmin nroute (google search) and install this also on your pc, connect your garmin gps on the pc and use nroute to track your route. Hope this helps.
