Therion and DEM
by Xavier Robert 24 Jan '19

24 Jan '19

Dear all, For a quite large project, I am using a relatively high-resolution DEM (i.e. 1 px = 1 m), and I am trying to use it within Therion to produce a .lox-3D file. I am however facing some problems: If I export the full resolution DEM to a .th file (6540*4307 cells) with the line "grid 325816.2990788577 5106250.599820679 1 1 6540 4307 ». I have the error « therion: error -- dem.th [14] -- line too long ». This line 14 correspond to the first row of the DEM. ASC parameters are « #NCOLS = 6540, NROWS = 4307, XLLCORNER = 325816.2990788577, YLLCORNER =5106250.599820679, CELLSIZE = 1.0 » If I export the DEM with a 5 m pixel resolution (1308*861 cells) (with the line "grid 325816.299079 5106250.59982 5.001161440185831 5.001161440185831 1308 861 », I get the same error, If I export the DEM with a 10 m pixel resolution (654 * 431 cells) (with the line « grid 325816.299079 5106250.59982 9.996519721577727 9.996519721577727 654 431 »), everything compiles OK and the result is quite OK (https://www.groupe-speleo-vulcain.com/wp-content/themes/custom_theme/3d/JB.… ; be patient, it takes time to load), but not with the full resolution. The process to build each .th DEM is exactly the same, I do not touch any end of line. I edit the .asc DEM with vi to translate it into a .th file. I thus suspect that there is a size limitation for the DEM in Therion, I imagine a limitation in the number of row/columns of the DEM. Is that true ? If yes, what is this size limit for DEMs ? As anyone an idea how to overtake that and use the full resolution DEM ? Cheers, Xavier

Scale dependant error when using area fills
by Tom Foord 20 Jan '19

20 Jan '19

Hi all I'm having some problems compiling a project which includes debris area fills. Depending on the exact symbol fill that I use, I am getting strange scale-dependant errors which seem to cause the compiler to loop endlessly until I force it to stop. I originally noticed the problem when using a custom area fill that I made by modifying the standard a_debris_AUT symbol fill. I've attached my modified metapost definition in the attached text file 'a_debris_WUG.txt'. The error occurs for any scale between 1:2000 and 1:4483 (outside of this range the project compiles fine). See attached output log 'Output log - a_debris_WUG.txt'. As you can see, the file seems to loop over and over again. Initially I thought this problem was specific to my custom fill, but then I noticed that I also get a similar error when using the standard a_debris_AUT fill, however this time the error only occurs when the scale is set to exactly 1:2000 (any other scale seems to be fine). See attached output log 'Output log - a_debris_AUT.txt'. Can anyone help with this problem? Thanks Tom

XVI and PocketTopo txt XTherion file formats
by Adam Pyka 16 Jan '19

16 Jan '19

H All, Are there any documentation about the XTherion XVI file format (the structure, etc) and/or the .txt PocketTopo that can be imported? I know that I can do the reverse engeneering but it will be much more easier to find out the official source documentation. Cheers, Adam

Therion 5.4.2. potential bug
by Michael 09 Jan '19

09 Jan '19

Hello, Excited to see the new version being available, as not everyone is IT-savy enough to build it. Have installed (after removing 5.4.1.) and tested it on Win7. Seems to work fine, but – Producing a KML file for GoogleEarth results in the cave map being displaced towards NE by 100 meters or so. When I re-install Therion 5.4.1., the displacement is gone and the map is where it should be. Perhaps a glitch or change in the way coordinates are calculated? Regards, Michael.

Android emulator
by Bruce Mutton 06 Jan '19

06 Jan '19

Has anyone used an Android Emulator on Windows to view or edit TopoDroid or SexyTopo files? My desire is to be able to view such files on any device that can process a Therion dataset, once they have been incorporated into the overall project. I see there are lots of them out there, but I may as well start with something that a Therion user has already successfully used. These two look reasonably interesting; ARChon <https://archon-runtime.github.io/> Bliss OS <https://blissroms.com/> Recommendations? Bruce
