I'm a french user of therion and use it for caves and also ancient mines as I'm an archaeologist specialised in this domain. I think it could be interesting to share our practise with this software, to see what feets well our needs and we specially need...
This would be a very good idea! But you (and other miners here) are surely way more experienced with Therion than I, and while I learn fast it will take some time until I have interesting things to share. But that time will come soon as I have always a mine to survey, and I plan to do the work with therion. And I must confess that I have not the foggiest thought what the differences in surveying needs between caves and mines are, as I explored many mines but never a cave. Also I am of course unsure whether my needs or problems now (as a beginner) are trivial to solve with therion or are mining-specific in that sense. Currently I am anyway stuck as I have problems to generate .pdf files showing outlines and generally make pdf's to my liking (while eg. <http://www.nabble.com/Printing-xvi-maps-t4757317.html> helped a bit). Another problem that comes to my mind is that I have no idea to cope with the following eg.: I took lrud measurements along a mine galley, and noticed the endpoint of the measuring tape being badly placed. So I took a point, like "45cm to the right (in right angle to tape)", and continued with the next 'line of tape' (polygon stroke?) from there. So I have a piece of 'ghost centerline' I do not know how to get rid off that also counts in length of the mine, so to say. Any suggestions here would be most helpful as I have more surveying data involving such cases. Well, a great help would be if anyone could point me to an example of a therion example of a small mine with just a shaft and some galleys (or give me one; I would of course only use it personally as an example). I have some difficulties with applying the examples at <http://therion.speleo.sk/download.php> to my first mine. Greetings, Christian
