Data modified to obscure cave location, but this should work. The long/lat order is the same as you put in your cs statement. The "200" is elevation in meters.

Therion throws an error: "therion: warning -- data not georeferenced -- unable to export KML file" 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?
