[Therion] OFFTOPIC: how to get geographic coordinates (LAT/LONG) of all stations of a centerline?

[Mykyta Kozlov]

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
