How to avoid that symbol-colour area blocks fills the blocks with chosen color
by Torstein Finnesand 10 Nov '12

10 Nov '12

Hi! I would like to color sand, pebbles, blocks and other sediments as brown. I use Symbol-colour to this, like symbol-colour point pebbles [67 31 4] symbol-colour point blocks [67 31 4] It works fine. In some passages I have defined areas with pebbles and areas with blocks, so I use these as well: symbol-colour area pebbles [67 31 4] symbol-colour area blocks [67 31 4] It works fine for pebbles. But on the PDF map the area blocks get filled with the brown color. The result is that some blocks on the PDF-map are brown filled with no color and other blocks are brown and filled with the brown color. The attachment illustrates it. How can I get use "area blocks" to behave like other sediments when I want colors (and no filling)? Torstein Finnesand

FW: colour by map
by Bruce 06 Nov '12

06 Nov '12

Although the Therion Book pg 48 needs to be updated to state that -map-level applies to maps as well as to atlas'. Bruce _____ Subject: RE: [Therion] colour by map Thanks Stacho That works very well, down to multiple map levels as well, and layers! Makes my 'Output Map Title Override' hack http://therion.speleo.sk/wiki/doku.php/tex#overriding_data_supplied_by_theri on_map_headers redundant. Bruce

colour by map
by Bruce 06 Nov '12

06 Nov '12

After our recent discussion on this topic I read somewhere (cannot find it now) that one could control the 'colour by map' feature so that sub-maps <x> levels down from the primary maps selected could be coloured, and that the way to control this was with the select command. (This would be a useful feature - select a single primary map to enable Therion to determine the overall output pdf title, but have the various sub-maps coloured and labelled in the legend) (And another thought, perhaps sub-maps would have their own pdf layers as well??) Following the Therion Book I tried; select MiddleEarthPlanMap map-level 1 however with 5.3.10 this produces an error. "error -- thconfig-MiddleEarth.thc [32] -- unknown option -- map-level" Can map-level be used in the way I described above? What am I doing wrong with the select syntax above - Therion Book suggests it should be OK? Thanks Bruce

Color for one scrap in a Project
by Markus Boldt 05 Nov '12

05 Nov '12

Is it possible to define color-map fg only for one scrap in a Project of about 50 scraps in several surveys? I have an "all-thconfig" file for this Project and there I have defined a light yellow for the cave. And in the scrap which I want to have in very light grey I have defined this very light grey, but it will overwritten. Many thanks for Ideas. Markus

Projected Elevation
by Andrew Atkinson 04 Nov '12

04 Nov '12

I have a couple of caves (probably more) that could really do with a projected elevation, rather than extended. so I set off trying to do it. I started with one looking towards 90 degrees, but did not get any walls and the centreline was always projected looking north. Eventually found this http://mailman.speleo.sk/pipermail/therion/2009-January/002291.html Which indicates that in atlas this is all that is implemented. I assume it is the same for map? So I moved onto the cave that has a projection looking north. At least the centreline now looks right, but I am not getting any walls. Should I be, or is this not implemented either? Is the implementation of Elevation likely to happen, or should I start to look for another way? Andrew

Hi Laurent For one cave in the Dordogne, I used cs UTM31 The co-ordinates to fix the entrance were then read off from a UTM grid overlay on the digital (CD) version of the IGN map You may find this site helps http://www.geoportail.gouv.fr/accueil, though I seem to only be getting lat-Long or Lambert co-ordinates at present, not UTM Graham -- graham.mullan(a)coly.org.uk

My cave is on the middle of the sea on google maps ...
by cawa sorix 02 Nov '12

... and I'm not a cave diver. Hi all, I try to put my cave centerline on google maps, I generated the kml file without issue. But I don't know the espg code for google maps, I tried a lot of them, but I'm always on the sea, I try to convert to an other system, always on the sea... For example my fix point is in Lyon (France) on google maps, but with my kml file I'm not at the right location. Do you know the ESPG code for google maps ? or how to put google maps espg on therion ? I put cs espg:4326 fix P-0 45.775643 4.85397 Thank you Laurent.

FW: Doubt about vertical sections
by Bruce 02 Nov '12

02 Nov '12

…so to clarify further … As the gradient of a survey shot increases, therion switches from the assumption that passages are measured LRUD (vertical up down) to an assumption that they are measured LR-front-back (up down perpendicular to the passage orientation) and then at +-90 deg to the assumption that they are measured NSEW. You can control the inclination at which the first change occurs by adding vthreshold 40 degrees to your centerline block of data. Unfortunately we cannot change the NSEW behaviour (yet). What you need to know of course, is approach the surveyors took when they were collecting the data, and adjust your input accordinly. Bruce _____ From: therion-bounces(a)speleo.sk [mailto:therion-bounces@speleo.sk] On Behalf Of Bruce Sent: Thursday, 1 November 2012 7:08 a.m. To: 'List for Therion users' Subject: Re: [Therion] Doubt about vertical sections Marco I tested your example and got the result you described with both xvi and pdf outputs. I think you have found the transition defined by ‘vthreshold’. >From the Therion Book… “ vthreshold <number> <units> ◃ threshold for interpreting LRUD readings as left-right-front-back reading perpendicular to the shot. If passeges are horizontal (inclination < vthreshold), LR is perpendicular to the shot and UD is vertical. If passages are more or less vertical (inclination > vthreshold), even UD becomes perpendicular to the shot – otherwise passages would not look very good. In the case of vertical shots, UD is interpreted as north-south dimension from the station to allow tube-like modelling of verticals “ I had thought the default value of vthreshold was 60 degrees, but it seems it may be around 67.5 degrees.

Hello, I tried to make a .xvi for elevation and extended section starting from this dataset: survey test centerline units compass degrees units clino degrees units tape metres data normal from to length compass clino left right up down 0 1 10 45 -67 [1 2] [3 4] [5 6] [7 8] endcenterline endsurvey everything looks good, the up and down data are plotted in the right way. Then I changed the clino to -68 degrees and noticed that vertical sections were rotated in the elevation and extended xvi. Is that correct? Am I missing something? Here's the thconfig: encoding utf-8 source dati.th export map -proj plan -o pianta.xvi export map -proj extended -o sezione.xvi export map -proj elevation -o elevazione.xvi Thanks, Marco
