So I have most of the data for two caves in Therion. I have been able to produce centreline plots, pdf plan/profile and lox model of both caves separately and in relation to each other. They are linked by UTM entrance coordinates. I tried to make a KML file and got the error message: georeferenced -- unable to export KML file The fixed points is in the surveys (.th file with distance, compass, cline data) that contain the respective entrances. I wrote one thconfig file : encoding utf-8 source GloryRes.th layout GloryOle debug station-names scale 1 1000 grid bottom grid-origin 649402 5586275 762 m grid-size 10 10 10 m grid-coords border legend on endlayout export map -fmt xvi -layout GloryOle -o GloryOle.xvi export map -output plan.pdf -layout GloryOle export map -output profile.pdf -projection [elevation 30] -layout GloryOle export model -output GloryRes.lox export model -output GloryRes.kml Any help to make a KML file is appreciated.
