track to route

[80valley]

What program is good to use to change a track to a route? Thanks

Your track is made from a GPSr as you travel/hike. You typically save this so that you can view it in your GPSr, use the "backtrack" function, or export the track file to use on your computer in a map or geotagging program. Most GPSr units have a function to convert the track to a route that you can use the route in the field.

It is difficult to do this sort of conversion. A track can have thousands of points, whereas a route may only have a few. What model GPS receiver do you have and where are you wanting to use these tracks (trail or highway?)?

Try Topografix Expert GPS....

 

It's so difficult that the user has to select a track, then "right click" and choose "convert to track". That makes every trackpoint into a route point.

 

In reality, the user needs to first "simplify" the track (reduce the number of trackpoints) down to the desired number of preferred route points, THEN do the above "convert to route". How much/how many times you "simplify" and down to how many points is totally up to you.

 

The whole process takes less than 30 sec.........

GPSBabel can do this via filters, but it does require you to know what limits the consumer of the route imposes, as Rich describes.

Both are exposed in the new GUI in the beta version.
