G'day belgian46 & jcalmx55,
Here's a suggestion for you guys, so each of you can work this out calmly...
...Justin, I suggest that you create a *.kzm file (using Google Earth), which traces and includes ALL the lines radiating out of Pittsburgh that you wish your route to cover. If you don't already have GE installed on your machine, then you WILL have to download it for this purpose (you will also need to 'learn' how to create a *.kzm file but all of the required instruction is available at your fingertips from the good people at Google Earth). Once you have the file, you can then pass it on to belgian46, where...
...Kurt, you can import this file into TransDEM and use it as a standard polyline route to obtain the required Topographic Maps from the USGS, using the WMS in TransDEM (or the Google Earth Photo-imagery, whichever is required), to complete the route to specifications, finally using TransDEM to provide the required DEM data (NED 1/3 arcsec data recommended - obtained from the USGS, again) and ultimately export the route as required for Justin. You will also be able to use the *.kzm polylines (with tweaking, if needed) as the basis for TransDEM's 'spline' function if it is decided to 'go down that path')...
...doing it cooperatively, in this manner, saves any misunderstandings and ensures that Justin will get everything he wants and you have everything you need to create the route, so long as Justin fully understands that all he will get is a "Bare Bones" route without anything other than the USGS standard topographic map shown on the terrain (or perhaps, the railway tracks), which has been created using DEM data...
