Hello everyone - I am trying to create a KML file. 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? Thanks - Bill Gee

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. I'm pretty sure it's optional. # Tie the Survey to a GPS point at the entrance. cs long-lat fix 0 -86:10.100 37:40.100 200 station 0 "My Entrance." entrance On Mar 22, 2015, at 6:10 PM, Henry Bennett <henry@hbennett.com> wrote: Use Fix http://therion.speleo.sk/wiki/doku.php/tbe:wiki2?s[]=fix&s[]=entrance -----Original Message----- From: therion-bounces@speleo.sk [mailto:therion-bounces@speleo.sk] On Behalf Of Bill Gee Sent: 22 March 2015 21:48 To: Therion Mail List Subject: [Therion] How to create KML files Hello everyone - I am trying to create a KML file.

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. Cheers, Olly
Thanks Olly, Henry and Adam - This was enough information for me to get a KML file out of Therion. I sent it off to someone else to verify that it lands in about the right place. Google Earth has a Linux version, but it is badly supported and very buggy. Now that I know the secret incantation, I can change to UTM if needed. The cave in question is probably in zone 15. The border between zone 14 and 15 runs right down the middle of Missouri which causes us no end of difficulty. The readings for this cave were not done by me. And one point to verify ... Therion DOES require elevation. I tried it without and it complained. Regards - Bill Gee On Sunday, March 22, 2015 23:14:44 Olly Betts wrote:
