GPS & Digital Data Discussion / How to create usable routes for TA?
« on: April 28, 2008, 06:08:53 pm »
My goal is similar to Kathy's--I'm trying to use TA's downloadable GPS routes for the TransAm, with a minimal amount of editing. I downloaded them into Mapsource and created 3 sets of routes to fit within the limits of my Garmin GPS60CSx. City Navigator is loaded on the memory chip.
The problem is when I recalculate the route either in Mapsource or on the GPS unit, the length of the route doubles or even triples in length. This is in spite of my routing setting for bicycle, no toll roads, etc. In Mapsource, there is no selection for "no Highways", but I selected "Prefer Minor Roads." I know that one of the causes is to avoid bike paths, but what else is going on?
How can I create routes with directions that more faithfully follow the AC route without laboriously comparing the GPS mappoints turn by turn with the AC paper maps?
I believe I'm following the procedures provided by Paul Taylor and Alex Carr. Thanks.
