Compiling Therion projects from Notepad++
by Footleg 08 Jan '15

08 Jan '15

I find having multiple thconfig files open so I can compile different parts of my large cave system project very useful. So I was investgating how to run Therion from Notepad++ (my preferred text editor). This is how I got it working: I wrote a 2 line batch file containing these commands: cd %1 "C:\Program Files (x86)\Therion\therion.exe" %2 Saved to somewhere on disk, and then call it from Notepad++ using the Run command, as follows: On the Run menu in Notepad++, Select the 'Run' item, and enter the command as follows: "C:\Personal\Caving\Therion\compileTherion.bat" "$(CURRENT_DIRECTORY)" "$(FILE_NAME)" (But using the path to where you saved your batch file). Save the command (I called it 'Compile Therion' and gave it the shortcut CTRL+T). Now with any thconfig file open in a tab in Notepad++, I can compile that project by pressing CTRL+T, or by selecting 'Compile Therion' from the Run menu. You can create multiple thconfig files in the same folder on Windows, by giving them any filename you want with the extension .thc or give them no extension at all. That way all the files will be listed in the 'Open File' dialog from the compile tab in xTherion. Next I'll see if I can get my batch file to open the output PDF automatically in Foxit Reader :) But that will be less general because I need to pick a PDF filename which can vary between my thconfig files.

5.3.11
by Stacho Mudrak 06 Oct '13

06 Oct '13

Hello everybody, I have just uploaded version 5.3.11. Here is the list of changes: therion: * added -survey option for map for setting survey associated with map. For example all surveying statistics from this survey will be used, when this map is selected for output. * added sketch-colors <number-of-colors> option to thconfig file, to reduce size of sketch bitmap images in maps * hide symbol from legend, if it has explicitly empty translation * survey-level works for point station-name labels, if station name is automatically determined (no -text is specified) * symbol-show|hide group text for point label, remark, date and line label * grid-angle <value> <units> - can be used in centerline to specify magnetic grid angle (declination against grid north). * -cs output specification works for export cave-list (including lat-long) * dates are shown using OS locale settings in map export * layout statistics explo/topo-length on/hide/off -- if it is off, team members are sorted alphabetically * KML export format supported for cave-list and continuation-list * bugs fixed: - PLT export in output coordinate system - context point air-draught not working - instrument position in centerline does not work - debug scrap-names crashes if empty scraps - counter not working in centerline data diving - revise not working outside of survey context - wrong length/depth and other statistics calculation for map output - sketch bitmaps inserted multiple times in PDF files xtherion: * bugs fixed: - new file in xtherion works, even if file is already open Merry Christmas :) S.

Error 768
by Andrew Atkinson 06 Sep '13

06 Sep '13

Hello Debian wheezy. Therion 5.3.9 and 5.3.10 First some history. I was using 5.3.9, but last weekend I was running a course in Wales so needed the OSGB:SN which is added to 5.3.10. So to achieve this built 5.3.10 from source as 5.3.10 is not in wheezy due to the freeze. So when producing a pdf I get the Error 768, log attached, everything else I do seems to work as normal Wookey was there to help, so also tried installing 5.3.10 from .deb and then 5.3.9 from the .deb, both with the same error. Now in the error there is the bit that says ! Unable to make mpx file. l.2 btex \mainfont 0 etex The two files given above are one of your source files and an auxiliary file I need to read to find out what your btex..etex blocks mean. If you don't know why I had trouble, try running it manually through MPtoTeX, TeX, and DVItoMP played around with this, but really do not know what I am doing, but it might help me trace the problem. 5.3.10 worked on Wookeys Wheezy machine, so the w/e training could continue, at least. This was generated when running the thconfig file in http://www.cave-registry.org.uk/svn/CheddarCatchment/Reservoir/ Thanks Andrew

Typical Head of Water between entry and exit of sumped passages
by Footleg 27 Jun '13

27 Jun '13

I am working on a master survey of the Kingsdale System in Yorkshire, UK. There is a substantial submerged portion to the system. Over a rough distance of 1500m of sumped passage, what difference in water levels could be expected between the upstream and downstream ends of the sump? The diving data just records water depth, so it computes both ends of the sump as having identical water levels. We know in flood conditions the upstream sump level backs up considerably. But assuming the diving is done in conditions of low flow, what typical difference might be reasonable to expect in the altitude of the resurgence and of the upstream end of the sump (determined by survey data from an entrance)? My data shows a significant difference, but I do not know how much of that difference might be expected and how much is due to errors in the dry passage survey and entrance altitudes? Footleg

Footleg said: > what difference in water > levels could be expected between the upstream and downstream ends of > the sump? and Wookey responded: > This is a question for hydrologists, not cave surveyors :-) Wookey is wrong. Without the data from survey and from geodesics the hydrologist would have no way of knowing the facts of this. In science, observation comes first :-) Graham -- graham.mullan(a)coly.org.uk 0117 9502556 or 07887 637064 (or 0844 2327803)

Fwd: Diving data loop closures altering depths
by Footleg 17 Jun '13

17 Jun '13

This is a Survex issue but may also be of interest to this list. Plus the Survex list does not accept my 7 KB of data as it says my post is too big. Posting the data here for lack of a capable list for Survex. Footleg ---------- Forwarded message ---------- From: "Footleg" <drfootleg(a)gmail.com> Date: 17 Jun 2013 14:38 Subject: Diving data loop closures altering depths To: "survex" <survex(a)survex.com> Cc: Trying to track down why some underwater data was several metres higher than a sump water surface, I discovered that closing loops between stations at the same depth in diving data alters the depth of surrounding data. This was not expected! I've attached a fragment of the data which illustrates this. Without the loop closed: Station entrance.030 is at depth -5.30 Closing the loop: *equate Entrance.010 EntranceLoopNorth.019 where both these stations are at the same depth, but horizontally displaced (a common scenario as depths are absolute but length and compass errors accumulate in diving data), now: Station entrance.030 is at depth -5.48 Is this a bug, or have I not understood something here?

Using autonamed station named from PocketTopo sketches in complex projects
by Footleg 16 Jun '13

16 Jun '13

Having embarked on drawing up a larger cave system with data from various sources, I discovered that PocketTopo sketches brought into the drawing editor just get names local to that sketch (e.g. 3.3, 3.4, etc.) but my project builds up the centreline from multiple centreline surveys. So the actual name of the stations in my cave is like 3.3(a)subsection.dataset.cavename Thinking there must be a solution to this, I searched the wiki, and found it (Thanks Bruce!). I can use the -station-names option on my scraps in the sketch to say what the full name of the station should be. But my station names do not need a prefix (it is already set from the xvi file by the editor) and with a bit of experimentation I discovered that to omit the prefix I have to put a pair of double-quotes as the prefix. This works, but is there a neater way to do it? e.g. -station-names "" @ShortDryWay.swildons means my station with -name 3.3 will be treated as 3.3(a)ShortDryWay.swildonsin the scrap and this is what my station in the complete cave centreline data is named so it works. It just seems unintuitive to have to give a blank prefix this way. Bruce's example also includes author and copyright options on the scraps. How does Therion use these? Or are they just allowed on the scrap options but not used in any generated output? While reading Bruce's excellent advice pages on data structures I spotted some places where more recent developments or ways I work make things easier since the section was written. So I've added a tip on getting data off PDA via memory card, and a link to Andrew's TopParser application to this wiki page: http://therion.speleo.sk/wiki/doku.php/paperless#data_transfer_from_pockett… Footleg

Selecting different maps for output in one config file
by Footleg 16 Jun '13

16 Jun '13

I am trying to generate PDFs for different parts of my cave using named maps. But if I select one map, export it and then select another and export that all in one file then it appears all the selects are processed before any exports. So all my output PDFs are the same. e.g. The following config file: source swildonsmaster.th select EntranceSeriesPlan@SwildonsHole export map -projection plan -layout local -o swildons_ent_plan.pdf select testPlan@SwildonsHole export map -projection plan -layout local -o swildons_plan.pdf Does not give me a PDF of just the entrance series. I get two PDFs of the testPlan map. Is there any way to do this from a single config file? Footleg

How to mark station with labels and make them appear in plan and extended projection
by Marco Menchise 16 Jun '13

16 Jun '13

Hello, maybe it's a silly question, maybe not: It would be useful to have a station point labelled with some text and get the label appear either in plan than in extended projection. I made many attempt to achieve this but I cannot see any label unless I define a "label" point in 2 .th2 scraps (one for the plan, another for the extended projection) and include them in the map. I know it is possible to label a station in the centerline file but the label does not appear in projections. I was searching if there is any simpler way to get those labels visible than defining 2 scraps. Thanks, Marco

map offset, why not scrap offset allowed
by Bruce 13 Jun '13

13 Jun '13

The Therion book 5.3.11 says, for map syntax, pg 31; if you refer to map, you can specify offset at which this sub-map will be displayed together with preview type of its original position. Syntax is following: <map reference> [<offset X> <offset Y> <units>] <above/below/none> If I specify a scrap to be offset instead of a map, no error is generated, but the scrap is not offset. Is it likely that one day soon we might be able to offset scraps, or is there a good reason why this should not be possible or desirable? If not, then perhaps a warning message should be generated to say that the scrap could not be generated. Regards
