KML from Therion no longer working in Google Earth?
by Footleg 15 Feb '12

15 Feb '12

I don't know why, but kml files for my surveys produced by Therion appear to have stopped working in Google Earth. Any therion kml file I try (including ones which worked in the past) now just show a point in central Africa with the whole continent visible at the zoom level. If I zoom to where the cave survey should appear then I see nothing there. I have attached a very truncated sample kml file (I deleted most of the points from the polygon to keep it simple. Footleg

Inkscape as map (pre)editor for Therion
by Martin Sluka 31 Dec '11

31 Dec '11

Thanks to Thomas Holder we may use Inkscape drawing package to draw or edit or convert .th2 files. Not with all the features of xtherion (missing object area, changing subtype of line point, ...) but with several features long time requested. Moving objects, selecting more objects, ... See: http://therion.speleo.sk/wiki/doku.php?do=show&id=inkscape I tried the Inkscape importing to therion some svg maps and the possibilities of Inkscape/Therion package are very promising. Anybody else? Only be careful not to make too large scraps and use beziers and not automatic lines with zillions of points! Happy New Year 2012 Martin s.

There is a request from one wikipedia editor: xxxxxxxxxxxxx Are there any reliable, third party sources which can speak to the notability of this software? I see that people are using it as witnessed by the articles in newsletters; but, I don't see any reliable sources. WTucker (talk) 06:02, 13 December 2011 (UTC) xxxxxxxxxxxxx So may you add the links to your project pages or send me a link I'll do it. Martin S.

Hello What are you think about second behaviour of "flags" command like second behaviour of "extend"? Example: flags duplicate 1@survey flags not duplicate 2@survey flags splay 1@survey 2@survey It is make possible to keep such commands in one place. -- WBR, Vasily

symbol-show fixed points
by Bruce 02 Dec '11

02 Dec '11

Hi All I've been trying to understand symbol-show and symbol-hide a little better as they relate to pdf outputs. How do I display the text associated with fixed points? I have some map objects defined for various caves in a large system. These are comprised of scrap drawings. I also have a map object with the minor surface features nearby, such as sinks, dolines, isolated entrances and significant navigational features such as fence posts or trees (for example). This is comprised of a survey only (mostly fixed points, and no scrap drawings) however and uses flags such as doline or sink, and most points have a text string associated ie. fix 15 2521640 6042938 581 10 10 30 station 15 "Concrete water trough" I would like to show the caves as outlines with all the rest of their symbology turned off, and the surface features with each of the points labelled with appropriate symbol and associated text. This is for an area map, at scales of say 1:5000 or 1:10,000 I can turn the cave symbols off with symbol-hide statements, and so far I think that is working out OK. However. -layout-symbol-show point flag:entrance \ -layout-symbol-show point flag:sink \ -layout-symbol-show point flag:spring \ -layout-symbol-show point flag:doline \ -layout-symbol-show point flag:dig \ The above layout statements cause the special entrance and sink etc symbols to be displayed, AND show the text string associated with the point. These are not displayed by default as far as I can tell, but these statements rectify that. -layout-symbol-show group all And the group all statement has pretty much the same effect in a more comprehensive and compact format. However none of the above enables me to display the text for my "Concrete water trough" example above. It is always just a cross with no text, or with '15' if debug station-names is on. It shows up in Loch, but not in pdfs. So, how do I display the text associated with fixed points? Is there a need for. -layout-symbol-show point fixed . or something similar? Also, sometimes I would like to display the point symbols (for the likes of the above flags) OR the text strings associated with the points, but not both at once. Is there a way of doing this? Thanks Bruce

selection of stations/shots for xvi export?
by Xavier Pennec 02 Dec '11

02 Dec '11

I have a cave which is quite complex and I would like to make elevations with different projection angles. My problem is that I cannot group all the shots for each elevation in separate surveys, so that when I export the xvi sketch to draw my elevations, I got all the stations and shots. I put below an example of the big cloud of points that it makes in the xvi: this superimposition of all the shots which will not be drawn in the elevation prevent from seeing the stations and shots which should be drawn. Does anyone see a solution to select only the stations/shots that I need? So far, I duplicated the whole survey to keep only the points that I needed, but this has to be done for each connected component independently, which is not very easy.
