DistoX and PocketTopo with Therion
by Bruce Mutton 13 Apr '10

13 Apr '10

Hi there I have a Disto arriving hopefully in a few days, and looking ahead I've been tentatively trialling PocketTopo on my PC. I suspect therein lies my first problem. Perhaps it only has limited functionality on PC's? I can manually enter data, but I can not seem to draw passage outline. The Export Therion format does not seem to produce data in a format similar to what Therion normally accepts - after the data it produces some form of co-ords separated into plan and elevation partitions. Most of the survey stations are converted to 10 digit numbers and all of the keywords are in capitals. Much of the file content could be made Therion compatible relatively easily using a text editor, but surely this is not what is intended? Obviously there is something significant here that I am missing. Have searched about but have not found the solution yet. Does anyone have a small dataset that demonstrates the interaction between PocketTopo and Therion? Bruce

Have just noticed that 'explored lengths' are always reported as zero in continuation-list, They are correctly reported in caves-list and surveys-list. Bruce

version 5.2.8 uploaded to Debian
by Wookey 01 Oct '09

01 Oct '09

I uploaded a 5.2.8-1 therion package to Debian last night. Feedback/bugs very welcome. Known issues: 1) texturing on loch has been turned off in order to let it run at all on Intel graphics cards. 2) The wiki snapshot is rather old (same as for 0.5.1 release) - can someone furnish me a new one? 3) My therion svn is broken so it's not checked in yet.

Thank you for your kind response. My first requests are oriented to set easier the approach to Therion by other SW users (it's my problem, but the same for a lot o potential Therion future users). > > Therion's "import" command looses LRUD data. > > Yes, you are right. But it would be probably more easier to support > LRUD data in therion's import command. Would it solve your problem? Yes it does actually. I asked the other way just because it's a really simple way (just drag and drop) to play with my own data in Loch and then obtain a .th format to try and understand. Really immediate and useful for beginners. But, of course, if it requests a lot of work, then is better to do other most important things. Thank you for all.

Loch/Therion new user
by Giorgio Pannuzzo 25 Sep '09

25 Sep '09

I'm a new Therion/Loch user and I wish to learn something about them because I'm really interested about their great advantages and technical approach. A this stage I'm just playing with the programs using my old datasets, facing the lack (or difficulty to find) of several useful features. Occasionally I also found some bugs (using "infer equates on" command). Wishes: 1- A GUI command in Loch to set on/off on-the-fly the "Vertical Prism" feature (in CaveX slang). Really useful for the rendering of old (E.G. compass.plt) datasets, collected by traditional LRUD usage. As I understand, the vthreshold command can't be set to "off" even in Therion Options. 2- An "Export" option in Loch to create .th files from other format 3d Datasets imported (E.G. compass.plt). If I'm not wrong, the standard Therion's "import" command looses LRUD data. 3- More bitmap formats available for surface (ECW-TIF etc.) and the ability to use OziExplorer's ".map" georeferencing. 4- lots of other things I'm thinking around, leave them for next posts. Sorry for my poor english and thanks for your great work. Have a nice day. Giorgio Pannuzzo Italy -- Caselle da 1GB, trasmetti allegati fino a 3GB e in piu' IMAP, POP3 e SMTP autenticato?

Bug in Loch Viewer 5.2.11 not showing passages with LRUD data from Survex 3d files
by Footleg 25 Sep '09

25 Sep '09

I have found that the latest development build of the Loch viewer does not display all the centrelines in my Survex 3d file. It looks like it is the centrelines which have LRUD data, plus legs attached to these. If I show walls then these are rendered, so only the attached legs are missing. But if I hide walls then all the passages with walls data disappear completely. See attached comparision screenshots from 5.2 and 5.2.11 with and without the walls shown. Footleg

ESRI output
by Dave Clucas 15 Sep '09

15 Sep '09

I have been trying out the ESRI model and see that it only exports shots, stations and walls. I would like to use the areas, particularly areas of subtype water in order to create an underground river shape file. Could you put this on your TODO list please.

seperate layers for surface and sketch images
by Bruce Mutton 15 Sep '09

15 Sep '09

Hi again Getting back to the task of including our existing paper maps in our Therion datasets. We have a large cave, with the existing plans comprising more than 5 overlapping sheets, representing differing regions and levels of the cave. Is any progress planned on separating the sketches from the surface layer in pdf outputs? If so I'd like to put in a request for each sketch to have it's own unique layer, and to support the transparency feature already implemented for passages and the surface. Are there any issues related to this (other than large run durations and file sizes)? Bruce
