Therion Output Export Selection and Formats Explained
Therions outputs are either biased towards presenting survey centerline information or biased towards presenting drawing information.
This is complicated by the ability to select for output survey centerline information and drawing information independently (and Therion’s various default selection behaviours) within the same th-config compiler file.
And further complicated as each of these two output types (centerline & drawing) ‘borrow’ information that is entered in the other (eg lox models ‘borrow’ drawing outlines, continuation–lists borrow continuation points from drawings, maps borrow centerlines (if they are defined to include particular centerlines)).
The result of all this is that, for example, a survey-list and map exported from the same th-config compilation will quite possibly not represent exactly the same parts of the cave system and thus produce differing statistics. This is a natural consequence of Therion treating the centerline survey and map drawing quite independently, and allowing the user to select each type of data for output independently. The other consequence is that users may get confused because, for example, sometimes pdf and kml files are the result of map exports, and sometimes they are the result of model exports.
