Hi Beni, first, I am sorry for the late answer. Do I understand you correctly, that you want to mix "select survey" and "unselect/offset particular map"? To be able to export all maps from a given survey without the need of specification of the master map for this survey. Am I right? Select survey and unselect survey seems to work for me. But unselect map is missing/not working, neither combination of map/survey select/unselect. Normally - if map selection for a given projection is available, it is used. If not, survey selection is used. I think, unselecting/offsetting maps from survey selection is feasible without any negative side effects. I am just not sure, how much work would it be to implement it. S. On Thu, 9 Dec 2021 at 10:37, Benedikt Hallinger <beni@hallinger.org> wrote:
Hello, I currently experiment with creating a nice overview map of a fairly complex part of the Hirlatz cave. The dataset spans about 8km in passage lengths in variuous levels with lots of over-/underlaying passages. The data is organised in surveys, where each survey defines at least a "Hauptmap" wich usually includes all the submaps the main map is composed of. The main intend of the "Hauptmap" is to nicely render the survey alone.
Now I want to create an overview map and using the select statement I can easily instruct therion to suck in and render all the maps of the entire region. Offsets are stripped this way, but therion does a very nice job in sorting te maps according to the altitude, which eases my brain very much, since i don't need to wrap my head around sorting 54 maps by hand. Therion does a splendid job with this already.
However this produces one problem for me: I cannot render map offsets easily anymore. So what I had to do is to select the entire region using "select Wandaugenlabyrinth.Hirlatzhoehle" and render that. This will print the processes maps into the therion.log file. From there I have picket it up to create a new "map" structure (`grep ^M therion.og |sort -r | awk '{print $3}'`). This i added to the thconfig file and selected that instead. There it is now easy to define offets again.
BUT: This introduces another, long term problem: When sometimes in the future someone adds a new survey to this region, he needs to remember to merge its maps also into the overview map definition (at the correct position because of altitude!).
Thus, it would be cool if we had some kind of "offset" thconfig command alongside the select one. This would allow me to read in the entire regions maps, and just specify offsets for the offset ones; something like this:
----- thconfig ----- source ../../therion/Hirlatzhoehle.th select Wandaugenlabyrinth.Hirlatzhoehle # read in all defined maps of the Region
offset 173-Anschluss-177@173.Wandaugenlabyrinth.Hirlatzhoehle [20 15 m] below offset 177-Hauptplan@177.Wandaugenlabyrinth.Hirlatzhoehle [-30 -20 m] above --------------------
Expected result would be all the maps read and printed at their altitude level, but the two maps offset as already known from the "map" command. If someone adds, lets say, 200-Hauptplan@200.Wandaugenlabyrinth.Hirlatzhoehle and recompiles the file, the new survey would be included *without specifying it explicitely*.
Is such a command possible? I know it's not such a big deal with smaller caves, but in my dataset this would save a tremendous ammount of time down the road when I will make the atlas of Hirlatz regions (not to mention a big overview map).
ps. and probably relatet: When I give "select Wandaugenlabyrinth.Hirlatzhoehle" and then "unselect 177-Hauptplan@177.Wandaugenlabyrinth.Hirlatzhoehle", 177 survey is still printed to the map. I would had expected that the scraps of the map would be hidden from output.
