I think this is because I have not included latitude/longitude information.
My question is ... How is latitude and longitude specified?
Reading through the Therion book, it seems it is done in the "cs" statement within the centerline. However, the syntax is not clear. Are there any examples that show how it is done?
Use Fix

You need to both specify a coordinate system with "cs" *and* use "fix" to locate at least one station in that coordinate system, e.g.: cs long-lat fix entrance -77.0365 38.8977 30 That assumes datum WGS84 (which is what your GPS probably gives you by default). You can't use lat/long as the output coordinate system, as that needs to use length units. I don't know off-hand if therion picks a suitable one for you - if not, you'll need to specify a suitable output coordinate system in your config file - e.g. 'cs utm<NN>' where <NN> is the UTM zone you are in.
