And this is from Samples: cave-list.thconfig: !PROCESS #!TITLE 4 Listing caves #! #! When surveying caves in some large area, you often need to generate #! an up to date list of all caves in that area. In therion dataset, "cave" #! can be defined in several ways, depending on the level of cave survey. #! #! If you have just surveyed entrance station (e.g. using GPS or standard #! surveying methods), all you need to do is to assign <code>entrance</code> #! flag using source centerline fix cave-1 123456 789101112 1234 fix cave-2 123333 789101122 1256 #!CODE station cave-1 "Unsurveyed cave" entrance #!ENDCODE #! #! If there is some explored passage behind this entrance, but you did not #! survey it properly, you should add also <code>continuation</code> flag #! and <code>explored</code> flag followed by explored length. Explored but #! unsurveyed passage lengths are also part of summary statistics. #! #!CODE station cave-2 "Unsurveyed but explored" entrance \ continuation explored 80m #!ENDCODE endcenterline #! #! If you have properly surveyed some cave, its data are usually in some #! <code>survey</code> structure. Survey becomes a cave, if it has main entrance #! station specified using <code>-entrance</code> option. Example: #! #!CODE survey small_cave -title "Tunnel cave" -entrance 0 #!ENDCODE centerline fix 0 123488 78910888 1244 data normal from to compass clino tape 0 1 100 -10 10 1 2 200 -20 15 station 0 "Main entrance" entrance station 2 "Second entrance" entrance endcenterline endsurvey survey xx endsurvey endsource #! #! If survey contains survey data, but it has no main entrance specified, it #! is not considered as a cave, just as data organization unit and thus not #! present in the cave list. Only surveys containing some caves (i.e. entrance #! stations or surveys with main entrance defined) are present in the final #! cave list table. #! #! After caves in your data have been properly defined, you can generate #! table using #!CODE export cave-list -o caves.html #!ENDCODE #! #! Resulting table looks like this #!HTML caves.html #!CLEAN caves.html And result Title Length Depth Explored Altitude Tunnel cave 25 7 1244.0 Unsurveyed cave 1234.0 Unsurveyed but explored 80 1256.0 So there is something I don't understand.

For list of caves it is "entrance 0" in survey section. Or should be. m.

Pavel Dňa 2017-01-09 15:52 Andrew Atkinson via Therion napísal(a): The Therion book states it has to be in survey, I tried entrance 0 in centreline, then you get an error, not enough data readings. Yes I know what it is meant to do, but it is not working, I will post examples when I am back in the UK, not easily done from rural Myanmar....

Then "export cave-list -location on -o cave.html" gives you coordinates and lenght and depth of your surveys compiled, conected with defined entrances. If you have a index.th [1], which connects all your caves (every cave has to be at least in one or more surveys; and more surveys connected under one general cave survey), then you have list of all caves with one or more defined entrances.

However, this gives an error unknown command -- entrance Now I can sort of get round it using Station 0 "" entrance in the centerline, but this does not define a cave so the list is a bit weird. Am I missing something?
