"\legendbox" "\loadpicture" and absolute paths
by rowena 14 Mar '21

14 Mar '21

Hello, I am using the "\loadpicture" capability in "\legendbox" constructs to include map sections, elevations, etc. It all works nicely on my PC where I am using relative paths to the pdf files. My club has a desire to archive the map data for posterity - ie if my pc dies or I go walkabout, the map data should still be available so that others can add to the maps as they are extended. I would prefer to have the images included using relative pathnames, rather than absolute pathnames, so that future explorers can download the map data and extend it, without having to duplicate my file hierarchy. How can I include relative paths in the \loadpicture functionality? Thanks, Rowena

Import a scrap into another scrap (or th2-file)
by torstein finnesand 11 Oct '17

11 Oct '17

Hi fellows, Sometimes I realize that two scraps should have been one (for instance scrap A in A.th2 should have been a part of scrap B in B.th2), in particular when it's difficult to join them. It's easy to insert the xvi file into the scrap B file. But I have to draw it again. Is there any workaround here? Torstein Finnesand Norway

Best practice - orientation of original sketch?
by Bill Gee 26 Dec '15

26 Dec '15

Hello everyone - This is not really a Therion question. It is more of a general survey question. Therion is sort of involved in the situation, though ... When you are drawing the sketch in the cave, is it normal to ALWAYS make north the same direction on each sheet of paper? What is considered "best practice" in this regard? Background: I have been helping with survey of a cave that has grown to slightly over 5000 feet as of a week ago. I have been both sketching and doing cartography. Therion is my weapon of choice! :-) At least 6 people have done some part of the sketching in this cave. All of us have oriented our sketches so as to best fit each section of cave onto the paper. We always indicate north, but it can be any edge of the paper. The man who is coordinating the project is also doing cartography using Windows tools (Walls, Xara, etc.) He sent me an email today asking if I will commit to making all future sketches with north being the top of the page. He asks because some of the computer work he does results in portions of the sketch being upside-down and therefore more difficult to read. Thanks - Bill Gee

Export to 3D processing softwares
by Martin Sluka 31 Oct '15

Therion and 3D Therion is able to export 3D model in format .lox based on LRUD data, shape of walls in plan and passage height informations recently. If the map is drawn in correct way these models are quite good. To view the model one should use internal viewer of Therion named Loch. The Loch has feature to export model in the VTK format. And several softwares for manipulating with 3D data for example CloudCompare or Paraview are able to import this VTK format. CloudCompare is able to export next formats: BIN .bin CloudCompare own format ASCII .asc,.txt,.xyz,.neu,.pts ASCII point cloud file (X,Y,Z,etc.) LAS .las ASPRS lidar point clouds E57 .e57 ASTM E57 file format PCD .pcd Point Cloud Library format PLY .ply Stanford 3D geometry format (cloud or mesh) OBJ .obj Wavefront mesh VTK .vtk VTK file format (triangular mesh or cloud only) STL .stl STereoLithography file format (mesh) OFF .off Object File Format (mesh) FBX .fbx Autodesk (Filmbox) File Format DXF .dxf Autocad DXF format SHP .shp ESRI Shape file format RASTER .geotiff, etc. Common raster formats (GDAL) PV .pv Point cloud + scalar field PN .pn Point cloud + normals Sinusx .sx Sinusx curves ParaView is able to work with next formats: ParaView files VTK files Parallel (partitioned) VTK files VTK MultiBlock (MultiGroup, Hierarchical, Hierarchical Box) files Legacy VTK files Parallel (partitioned) legacy VTK files EnSight files EnSight Master Server files Exodus files BYU files XDMF files PLOT3D files SpyPlot CTH files HDF5 raw image data files DEM files VRML files PLY Polygonal files Protein Data Bank files XMol Molecule files Stereo Lithography files Gaussian Cube files Raw (binary) files AVS files Meta Image files Facet files PNG files SAF files LS-Dyna files So you may for example calculate surface and volume of cave - thanks to Filippo Gregori: 1) Export the lox file to vtk format 2) With Paraview software I opened the file vtk 3) Save the file as .x3d 4) Open the file x3d in Meshlab software 6) Apply the filter: Filters -> Quality measure and computation -> compute geometric Measures 7) Open log window: View -> Show Layer dialog 8) Read the lines Volume Mesh and Mesh Surface

Re: [Therion] Plotting scraps and the centreline together
by Bruce Mutton 19 Oct '15

JennyI have always done what you are trying to do, and the solution is as Martin says, create maps from surveys and maps from scraps and then combine them.It is a bit tedious, but the default Therion behaviour you describe is to hide centreline for surveys that have no scraps (unless there are no scraps at all).. This is the only work around I have found, so if there is a better way let us know!Bruce Sent from my Samsung device -------- Original message -------- From: Martin Sluka <martinsluka(a)mac.com> Date: 19/10/2015 22:22 (GMT+12:00) To: List for Therion users <therion(a)speleo.sk> Subject: Re: [Therion] Plotting scraps and the centreline together Jenny, It looks the problem is you want to mix maps defined from scraps and maps defined from surveys. Try to draw „blind“ scraps only with stations and generate map from scraps. As I may say, I newer tried to define map as this: map from_surveys_only.map survey1 survey 2 endmap map from_scraps.map scrap1 scrap2 endmap map all.map map_from_surveys_only map_from_scraps endmap thconfig: select all.map m.s. > 19. 10. 2015 v 6:23, Jenny Black <jenelopy(a)gmail.com>: > > Hi, > > I want to plot both the centreline for the entire cave and passages in > the scraps I have drawn.

Therion's Loch features (incognito) on NZ TV
by Bruce 19 Oct '15

19 Oct '15

Loch model of 39 km cave features in this TV news clip at 3:47 (Me carrying two packs on the opening still, and stuck at 2:00) http://www.3news.co.nz/Deepest-cave-discovered-in-our-backyard/tabid/817/art icleID/330973/Default.aspx Centreline data has been processed for the last few(?) decades with a home-made unix application that uses proprietary routines, so will only live while Jonathan is with his current employer. As you might have guessed, an 'export to Therion' routine is being worked on. Bruce

Do people use Toughbooks for mapping
by rowena 19 Oct '15

19 Oct '15

Hi, Does anyone use a Panasonic toughbook for caving? Do you get the DistoX data direct uploaded to Therion on a toughbook? If so how well do they go underground and what other mapping tools do you use with it? Rowena

Plotting scraps and the centreline together
by Jenny Black 19 Oct '15

19 Oct '15

Hi, I want to plot both the centreline for the entire cave and passages in the scraps I have drawn. I can do one at a time but can't figure out how to plot both. In my thconfig file I have: symbol-show point station symbol-show group cave-centreline symbol-show point station-name debug station-names so when I don't have any scraps, I get the centreline and stations nicely plotted for the entire cave, which is proving very helpful with figuring out where to break loops for my extended elevation. However, as soon as I add in my scraps, which I've been doing by adding: input 107ee_ropeless.th2 input 107ee_china_new.th2 input 107ee_oldroute.th2 to my .th file I can only see the centreline (and walls, etc) for the scraps of drawn and not the rest of the cave. I'm sure it is possible to plot the scraps *and* the entire centreline. I'm sure I read it on a mailing list post when I was looking fro something else, but I can't rmanage to re-find it. Can anyone help? In case it makes a difference, I am plotted an extended elevation and reading in survex data as a 3d file. Thanks, Jenny
