I have been trying to create a model of an area on Montenegro. This area uses a local map system VGI which I thought was EPSG:3908

 

origin 18 degrees E

scale 0.9999

false easting +6500000

false northing 0.0

 

Dx +653

Dy –212

Dz +431

Da +740

Df –0.00010441

 

When I use these in a gps (user grid etc) they produce the correct VGI coordinate to match the maps.

 

I successfully produce a kml file but all the caves are about 400 east of where they should be.

 

Is EPSG:3908 useable in Therion?

 

A second little point, that I may have seen somewhere and now lost.

How do you mark an entrance to show up as a point on a kml file

I have used this for the lox output
