I would like to be able to import my after the fact GPX file which is based on traveling using the route I've developed using S&T and determine the precise travel time, the precise route, and other comparatives. I can do that using Delorme's
Street Atlas USA and do so, but I use S&T to develop most of my routing in the first place, so having to switch to Delorme for this purpose is a bit annoying. I also use RouteConverter.exe to add elevation information to my GPX files, but again would like to be able to do so in S&T
