Re: [Therion] Joining maps with the join command
Hi Bruce, > But looking at your original post, I think maybe you have a join inside > a map definition. Oh my goodness. Nail on the head, sir! I owe you one. My command was already correct (after Benedikt explained that scraps do not belong to a map, and to reference the scrap as a child of its survey), I just put it in the wrong place. Failed to recognise the context options for the command. For anyone else who finds this thread while looking for help, this is a summary: Both the line/point IDs and the scrap IDs can be referenced within the survey where they are created/imported. You can either tell it to automatically connect the best fitting points of the scraps (with the optional -count parameter to tell it how many passage ends join with the other scraps). Or you can manually select each linepoint in one scrap that should connect with which linepoint in another scrap. cave1.th: survey cave1 input "cave1 plan.th2" input "cave1 ee.th2" map cave1MP scrap1 scrap2 endmap centreline ... endcentreline endsurvey cave2.th: survey cave2 input "cave2 plan.th2" input "cave2 ee.th2" map cave2MP scrapa scrapb endmap centreline ... endcentreline endsurvey Then I have an overall file which combines the maps called allcaves.th: survey allcaves input "cave1.th" input "cave2.th" map allcavesMP cave1MP@cave1 cave2MP@cave2 endmap #either join scrap1@cave1 scrapb@cave2 -smooth on -count 1 #or join line1@cave1:end line3@cave2:0 -smooth on join line2@cave1:0 line4@cave2:end -smooth on centreline ... endcentreline endsurvey Another survey that uses "input allcaves" could also use one of these to reference the scrap or linepoint within the child "allcaves" survey: scrap1@cave1.allcaves line1@cave1.allcaves:end I do wish these error messages were a little more informative, pointing out where you made a mistake, but I am so glad it was something so simple. Does it actually not know what the problem is? Rather than saying "you put it in the wrong place" it says "the map item is not valid", which makes me assume a syntax error rather than a command hierarchy error. (My favourite error is the one where I forget to click on some survey stations when defining a scrap, and it tells me "this map is too large, and you need to pick a smaller scale". Or the one where I click on a station that was already defined in another scrap, and it fails to put the right -name in the options - or it just picks the "next" station number which was not the right one. Same error message. Or some random code dumps about it failing to find the largest coordinate when closing lines. These messages are ... "fun".) Many thanks to you all for the advice (and to Martin for offering to help debug). It seems that I have it working well enough now. Cheers!

Re: [Therion] Joining maps with the join command
>Sadly the only error message I see is "invalid map item" Common mistakes I have made; * Forgetting to have an 'endmap' statement * Mixing scraps and maps within the same map definition * Missing a dash at the start of an option such as ‘-title’ * Forgetting one of more “ surrounding a string (such as in -title “map title string”) But looking at your original post, I think maybe you have a join inside a map definition.

Ah yes, in my example I was simplifying to keep only the most important
lines visible and keep the question simple. That is one thing I should
have kept in :)
My real data does of course have the imports.

OK ... so that syntax does in fact exist. I had not expected it to be
valid (double @ symbol). I see Henry's example is using that same approach.
> join jpwall04@SwissM:end GUSwall02@Greenlink:end
I thought this is what I had used, but it failed. So I assume I have
done something else wrong somewhere. Sadly the only error message I see
is "invalid map item", which made me assume I was using the wrong
approach. It's not a particularly helpful error message, since it
doesn't tell me either the name it doesn't like, or the property that it
doesn't like. Certainly don't want to complain about such an incredible
piece of software, but imagine how nice it would be to see this:
"invalid map item: jpwall04@SwissM:*end*" ("end" is in bold/red)
With such highlighting, I would quickly be able to see that the initial
scrap reference is good, and the line reference is good, but the
linepoint is wrong. Oh well, this is probably not the best place for a
feature request.

Yes, I had wondered how to join mine in a place where there are some
oxbowing avens (the caves join vertically through a series of holes,
only the main one of which is surveyed with true legs), without using
walls. It seems -count is indeed my answer! Very nice, thanks.
So now back to wondering what it doesn't like about my (apparently
valid) join.

Re: [Therion] Joining maps with the join command
Tarquin As Benedikt mentioned, scraps are joined, not maps. If you join scraps, the maps that use those scraps will automatically show the join, so the maps themselves are not relevant to the joining process. I have an example of a three cave system that we surveyed and subsequently joined in 2007-2008. The highlighted words are the names of the respective cave surveys. For one of the joins, we could use a simple (and recommended) scrap to scrap join, using scrap_ids; join GreenlinkUSumpsPlan_s2@Greenlink GreenlinkFPlan_s1@MiddleEarth -smooth on For the other pair of caves, I have lots of lines within each scrap that crossed from one to the other, so I had to use the more complicated line by line joining, that you seem to be trying to follow, using line_ids; join jpwall04@SwissM:end GUSwall02@Greenlink:end join jpwall03@SwissM:00 GUSwall01@Greenlink:0 join jpwall06@SwissM:end GUSwall03@Greenlink:0 join jpwall07@SwissM:end GUSwall04@Greenlink:end join uwall04@SwissM:0 swall02@Greenlink:end join secondwall01@SwissM:0 swall05@Greenlink:end Although looking at it now, with the benefit of 10 more years of experience, I wonder if I could have used a simpler scrap to scrap join, with the -count 3 option. [Refer to the description of join on page 40-41 of The Therion Book]. Depending on the details of your data structure, there may need to be subtle differences in the way you reference the scraps, but looking at your description below, I think the style of scrap referencing I have used should work for you (probably). If it does not, you could try removing the (highlighted) cave survey names.
