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

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.

Re: [Therion] Scrap is too large to process in metapost in this scale
by Mihai Terente 27 Nov '11

27 Nov '11

It seems it will work if I add station points with the .xvi layer activated as background image. Initally I disabled the layer because of the grid, which I found quite annoying, and I kept only the morphed images. It seems that in this way the program didn't recorded well the coordinates of the points. Otherwise, with the .xvi grid and centerline visible, if I add a station point it recognizes its name automatically, and the coordinates are a little bit different, with lot of decimals. For the moment it compiles fine, in both .pdf and .shp format. Cheers, Mihai T.

Self adjusting label positions and missing point +s
by Bruce 26 Nov '11

26 Nov '11

I have just discovered a wonderous thing. Where surface points in a survey centreline are included in a map, the labels will self organise so that they don't overlap. See example 1 and 2 attached. This effect goes away I think when the points are included in a scrap. It also does not have effect between separate map objects. Is this default therion behaviour, or is it directly inherited from tex? Could it be implemented in outputs derived from scrap drawings? Now on to my short-term deadline question! Why might example 1 have +s in on all the points and example 2 have all the +s missing? I have not done any redefinition of points (unless by accident, and then they should be identical), and I think my symbol-show, symbol-hides are similar (though not the same I admit). Both the images are from the same dataset, just in different regions a few km apart, and also in different parallel branches of the survey structure, so somewhat independent of each other. Both have caves displayed in a similar manner to example 2, it's just that the caves in example 1 were not included in the screenshot. As you can see, the map structure in example 1 is very simple (the old paper cave map was traced in outline only in therion), whereas example 2 has perhaps 100 maps as it is a 15km cave drawn entirely with therion. I have turned off the layers which would have made the image confusing. Any guesses as to which symbol-show (or other statement) directly effects the + part of the point symbol, as I would like to show them in both cases? I'm also still looking for a way to show the labels for fixed points (and leave other point labels unaffected). What is the 'property' that Loch uses to make the distinction in it's data file? Bruce

New symbols
by Stacho Mudrak 26 Nov '11

26 Nov '11

Hello everybody, after drawing a complex map of one show cave, I would like to add new standard symbols to therion. These should include: line edge - should be used to draw other then rock edges, e.g. wall structures in elevation. There is already rock-border -- rock-edge pair, there is general border symbol but no general edge symbol. line rope - already discussed here, just line point option anchor on|off should work also line handrail - this symbol already exists in some cave symbol sets. A line with dots in plan, in elevation some standard 1m tall handrail would be drawn. point handrail - used to draw handrail in cross-sections line steps - should be used in both, plan / elevation projections. In plan, this line would surround steps area and steps would be drawn parallel to the first line segment. In elevation, 20cm steps would be drawn. line path - used to draw concrete or other path in caves, where it was built. If it will be closed curve, it will be filled with "area path". See below. area path - fill for path areas. It would be automatically applied for closed line steps/path in plan projection. Also should be added: line rope-ladder line fixed-ladder line via-ferrata point via-ferrata Do these symbols make sense? Any comments? Any other symbols, that should exist in the standard therion library? Thanks a lot for the feedback, S.

create area filled with a colour
by Mihai Terente 26 Nov '11

26 Nov '11

Dear friends, Is there a way to create a simple filled area? Suppose I want to create a black area enclosed by a line of type border to draw the outline of a pillar, which is to big to be represented as a point symbol. Mihai T. www.iser.ro
