Hi, Method 1: Export centerline to kml format in therion: export model -fmt kml -disable splay-shots -o your_cave_cl.kml
Then you can use a GIS package to extract coordinates, or a simple text editor. Method 2: Export to database in therion and then convert cartesian coordinates to lat/long with help of GDAL/PROJ4/QGis: export database -o your_cave.sql at the bottom of your_cave.sql file you will have list of commands insert into STATION values (1, '0', 18, 387675.73, 6056702.67, 180.04); insert into STATION_FLAG values(1, 'fix'); insert into STATION values (2, '30', 18, 387690.02, 6056686.38, 181.05); insert into STATION values (3, '11', 18, 387696.58, 6056689.10, 179.76); ... so those triples are your output coordinate system locations. Usually the coordinate system is some sort of UTM over WGS84 ellipsoid (look at your survey which one), so you put that triple into txt file, separating values by spaces and run command line tool cs2cs from GDAL/PROJ4/QGis package: Following example converts cartesian coordinates in the LKS94 coordinate system, which has EPSG (SRID) code 3346 to lat-long over WG84, which has 4326 EPSG code, with precision up to 8 decimal digits (~1.1 mm accurate). cs2cs +init=epsg:3346 +to +init=epsg:4326 -f "%.8f" coords_file_lks94 > coords_file_wgs84 On Mon, Sep 15, 2025 at 12:35 PM Rodrigo Severo via Therion < [email protected]> wrote: > Hi, > > > I know this question is offtopic but I could not think a better place to > ask: how to get geographic coordinates (LAT/LONG) of all stations of a > centerline? > > I have been asked to produced geographic coordinates of all stations of a > centerline by some friends. > > Does anybody knows how to do it inTherion, Survex or whatever software? > > > Thanks in advance for any help. > > Rodrigo > _______________________________________________ > Therion mailing list > [email protected] > https://mailman.speleo.sk/listinfo/therion >
