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.

Issues with average azimuth calculation and backlino
by Alexandra Shturma 30 Sep '13

30 Sep '13

Hi Staho and Martin, My name is Sasha and I am one of Abris developers (abris.shturmsoft.com) Currently, we are working on Therion export and have ran into few issues: 1. 1. Average azimuth calculation is wrong for certain cases. For example, if we have azimuth=1 and back azimuth = 179, the resulting azimuth would be 180. However, the resulting azimuth should be 0. 2. 2. Cannot omit backclino with “-”: data normal from to tape compass backcompass clino backclino A0 A1 1 100.0 – 0.0 – Gives an error: -- invalid backwards gradient reading -- - Best regards, Sasha Shturma

point stalactites point stalagmites
by Bruce 28 Sep '13

28 Sep '13

I recently discovered 'point stalagmites' (plural) which is presumably new in 5.3.11 (but it may have been around much longer). Now that I've started using it I have discovered that the legend text has not been refined for these, which is easy to correct using the following statements in thconfig file. text en "point stalactites" "many stalactites" text en "point stalagmites" "many stalagmites" Would be nice to have corrected in future 5.3.12, together with mention of the plural symbols in the Therion Book. Happy caving Bruce

statistics carto sort order request for 5.3.12
by Bruce 21 Sep '13

21 Sep '13

With the addition of a third draughtsperson to our project, whose name comes early in the alphabet, and who has clearly drawn much less than us two oldies, it's become apparent that 5.3.11 sorts cartographers names alphabetically rather than by length of centreline associated with their drawings. Not sure if this was the case with 5.3.10, but certainly the default sort order for explo-length and topo-length changed with 5.3.11 as described here http://therion.speleo.sk/wiki/doku.php/faq#why_do_peoples_names_sort_alphabe tically_when_they_used_to_sort_by_length_of_cave_explored_and_surveyed To make matters worse, I thought I would display only the 'top 2' draughtspeople, statistics carto 2 and it dumped my name because it is alphabetically towards the end of the alphabet, despite having drawn most of the cave (well maybe second most, but at least 100x more length than the newcomer). I may have a bias due to conflict of interest, but it seems like an unsatisfactory situation to me that the 'top two' cartographers is based on alphabetical rank rather than drawing rank. Is it possible to make the carto statistics syntax and behaviour consistent with explo and topo statistics in 5.3.12? A sample layout of mine below shows how they all work together, and how what I am requesting might fit in. layout LayoutStatisticsNormal #----------------------- statistics explo all # all/off/number # names of explorers, or 'number' most significant explorers statistics explo-length hide # on/off/hide # adds each persons exploration length and toggles sort type statistics topo all # all/off/number # names of survey team members statistics topo-length hide # on/off/hide # adds each persons survey length and toggles sort type statistics carto all # all/off/number # names of authors statistics carto -length hide # on/off/hide # request to add each persons carto length and toggle sort type statistics copyright all # all/off/number # names of copyrights endlayout LayoutStatisticsNormal Bruce

strata and fault symbols
by Martin Sluka 13 Sep '13

13 Sep '13

There are definitions of two new symbols in MetaPost section of wiki: strata and fault. Because of all user defined symbols could not use automatic -clip off you should to add this option. With new version of Therion they should behave as section symbol - without -clip off. m.s.

image missing and import error
by Andrew Atkinson 13 Sep '13

13 Sep '13

Hello I have just upgraded to debian jessie which comes with Therion 5.3.10 When opening a th2 file I find that all my background images are not visable, also not listed in the background images on the right hand side So in a new file I try importing a jpg, one I have done before, it gives an error, the log of which is attached, as is the th2 file it produces, which looks okay at a quick glance. I also tried a .top text file import, again that I have successfully done before, with the same result, the xvi is produced. Trying importing an xvi it looks like the same error Suspect this is a debian bug, as no one else has complained so will file a report after this thanks Andrew

Export Full Backbearings from PocketTopo to Therion
by John Stevens 08 Sep '13

08 Sep '13

Export oddities from PocketTopo to Therion A while back, I noted that if you do a full back bearing of three readings straight after you have done to forward leg, PocketTopo recognises this as the same leg and numbers it accordingly. I have not found any documentation about this useful feature though. 2.10 1.139 64.25 -33.70 [1] 2.10 1.288 53.85 -61.89 [1] 2.10 2.243 304.70 -50.40 [1] "fissure in floor with sound of water flowing " 2.10 2.11 3.574 49.25 -15.19 [1] 2.10 2.11 3.574 49.06 -15.19 [1] 2.10 2.11 3.577 49.27 -15.23 [1] 2.11 2.10 3.576 229.26 14.68 [1] 2.11 2.10 3.575 229.37 14.68 [1] 2.11 2.10 3.577 229.60 14.80 [1] 2.11 0.599 96.53 74.98 [1] 2.11 0.201 156.69 -50.20 [1] If the back bearing was outside the automatic parameters, then it can always be forced and sorted later. i.e. make a note, station may be too close to iron work or buried iron in spoil/deads. PocketTopo and TopParser deal with these in different ways when it is imported into Therion PocketTopo averages all 6 readings for the output file but it also adds a blank line 2.10 64.25 -33.68 1.140 > 2.10 53.85 -61.89 1.288 > 2.10 304.69 -50.39 2.243 > 2.10 2.11 49.30 -14.96 3.575 > 2.11 2.10 0.00 0.00 0.000 > 2.11 96.67 75.01 0.599 > 2.11 156.63 -50.15 0.201 > This second line then has to be commented out or deleted once in Therion. Other than that all other outputs act as expected. TopParser on the other hand outputs both sets of readings as separate legs. This has an advantage but a couple of disadvantages. 2.10 - 1.139 64.25 -33.7 2.10 - 1.288 53.85 -61.89 2.10 - 2.243 304.7 -50.4 fissure in floor with sound of water flowing #2.10 2.11 3.574 49.25 -15.19 #2.10 2.11 3.574 49.06 -15.19 #2.10 2.11 3.577 49.27 -15.23 2.10 2.11 3.575 49.15 -15.2 Calculated leg from 3 above #2.11 2.10 3.576 229.26 14.68 #2.11 2.10 3.575 229.37 14.68 #2.11 2.10 3.577 229.6 14.8 2.11 2.10 3.576 229.31 14.72 Calculated leg from 3 above 2.11 - 0.599 96.53 74.98 2.11 - 0.201 156.69 -50.2 If I use this output, the length of the cave is doubled for the leg but I do get some nice 2 leg loop closure errors. The distance can be adjusted but adding flags duplicate and flags not duplicate lines around the duplicate leg. These loop closures then give me good feed back into where magnetic influences are within the cave/mine. 5.70% 0.4m 7.7m 2 -0.2m 0.4m -0.0m [2.7 - 2.8 - 2.7] 3.86% 0.2m 5.1m 2 -0.1m -0.2m -0.0m [2.8 - 2.9 - 2.8] 2.70% 0.2m 8.7m 2 -0.2m 0.2m -0.0m [2.11 - 2.12 - 2.11] 1.18% 0.1m 11.0m 2 -0.1m -0.1m 0.0m [2.9 - 2.10 - 2.9] 0.50% 0.0m 3.9m 2 -0.0m -0.0m 0.0m [2.12 - 2.2 - 2.12] 0.44% 0.0m 7.2m 2 -0.0m 0.0m -0.0m [2.10 - 2.11 - 2.10] 0.33% 0.0m 10.8m 2 0.0m 0.0m -0.0m [2.2 - 2.7 - 2.2] >From these it is easy to see which passage had a large iron pipe running down it, even those we kept a good distance from it. This now allows me to set that passage survey grade as lower for the loop closures. But with all these subloops, Therion does not like calculating the main loop error. The other main problem with the TopParser output is for the extended section. Here it plots both legs so the centreline and splays are in the wrong place for the drawings. So that output is totally useless and I have to go back and use the PocketTopo output for extended sections. So bit more work on TopParser and PocketTopo to make them both fully implement this useful function.

Surveys without centrelines
by Stelios Zacharias 06 Sep '13

06 Sep '13

Dear all, Can Therion put together scraps on the basis of the polygonal system of survey? (I think this is what it is called - it uses as set of triangles and only distance measurement rather than the distance, azimuth, slope measurements we are used to). A friend has a survey constructed with only distances taken from two points (and successive points) so as to create a flat area of triangles (it is flat because the "floor" is the sea and the water level is constant). There is therefore no centreline, but a series of points, each joined by two measurements to other points and all coming back to a known baseline. In the days of paper survey, the plan would be drawn with just a compass from one point to the next, beginning off the baseline. There exist a series of drawings of the cave, but on separate sheets of A3 paper, which could be digitised but they will need some way to be joined together (with errors shared from sheet to sheet), hence my question. Currently they do not join in a satisfactory way when the same stations are aligned from one sheet to the other. In a worst case scenario, I would imagine using trigonometry to create a centreline around the outside edge of the polygons, but if there is a simpler way, I would be glad to know it. Cheers, Stelios PS is this method called the polygonal method, or am I misremembering?

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
