Depth seems to be including surface legs
by Duncan 02 Apr '17

02 Apr '17

We surveyed the surface above an old mine to get a feel for how thin the roof is. See attached Loch screenshot. Unfortunately, the surface legs are being included in the Depth value displayed on the Plan PDF (see attached). Displayed value is 13m, it should be about 8m. 13m is the maximum vertical extent of all our survey legs. The centerline data for the surface legs has been flagged as "flags surface". These have been correctly omitted from the cave length, and cave length is updated when the surface flag is commented out. However, the vertical range does not alter when the surface flag is toggled. I expected cave depth to be the maximum vertical range of the underground data. Hope someone can set me straight :) Duncan

How to add authors of paper drawings, which is being digitized as therion scrap?
by Nikita Kozlov 01 Apr '17

Consider following task: Digitize old paper drawings of cave survey and include information about person who did digitizing and person who did drawings on paper. How it should be done correctly with therion th2 syntax? Are multiply -author command within same scrap supported (Ie oldest date corresponds to paper drawing, newest to digitising)? With best regards, Mykyta Kozlov.
