Re: [Therion] How to combine two maps

[Martin Sluka via Therion]

Bill,

if your way works it is OK. But according Therion's philosophy it could be better to create another 
"higher" "index" .th file which will include all your individual .th files:

survey all
input ./AllieSpringCaveSurvey/AllieSpringCave.th
input ./MillCreekCaveSurvey/MillCreekCave.th
input ./ShiftyRockPit/ShiftyRockPit.th

map #if necessary
...
...
endmap
endsurvey

Than in thconfig should be source all.th

In menu on right side of comparator window you may click on survey or map 
structure and check, how your data and maps are organised.

Well, that turned out to be easy! I was fearing a huge conglomerated mess of

As noted by several people - I put each cave survey in its own directory. Each 
directory contains a master .th file and a thconfig file. For bigger projects I 
create a subdirectory for each survey trip which contains the centerline data 
and all scanned sketches from that trip. It also contains the .th2 files.
 
One of the centerline data files (usually the first one) contains the GPS 
coordinates of the cave and also specifies the entrance station.
 
To create the combined map, I created a new survey directory. It contains only 
a thconfig file. The thconfig file names the three cave surveys like this:
 
# Name the three input caves
source ../AllieSpringCaveSurvey/AllieSpringCave.th
source ../MillCreekCaveSurvey/MillCreekCave.th
source ../ShiftyRockPit/ShiftyRockPit.th
 
The layout sections are exactly the same as in the thconfig files for each 
cave. The TeX code that I have for changing the size of the legend is also 
identical, as is the MetaPost code for drawing my custom symbols.
 
At the bottom of the thconfig file I listed the exports. The only thing I 
changed was the export file names. Everything else is the same as in the 
thconfig files for each cave.
 
# The main plan map
export map -proj plan -layout mainmapnocolor -o CaveRanch.pdf
 
# The main map for printing
export map -proj plan -layout mainmapprint -o CaveRanchPrint.pdf
(continue for kml, lox and 3d files)
 
When I ran therion with this thconfig file, it Just Worked! The first time! I 
was astounded. The output files contain all three cave maps and they are 
properly located relative to each other. WooHoo! That was easy!
 
The next adventure will happen when the link between two of the caves is finally

in a .th file - right? Which means, in the end, there will be four .th files mentioned in 
the thconfig. Is that right?
 
Thanks for all the help and suggestions.

Hi Bill

I think you have the answers you need already, but I’ll add my two bits
anyway.

I do almost the same as Ladislav.

Sounds like your caves are or should be part of one Therion project (simply
because they are in the same general locality). No need to change anything
other than to make sure all of the existing cave folders are collected
together in a single project folder (as in the image below).

In the example below, my project folder is th_TakakaValley/trunk (the
/trunk is just an artefact of the version control system we use) and there
are 7 caves.

The other folders are for outputs and standardised layout files.

I use a flat structure these days, ie each individual cave has its own
folder, with INDEX*.th and thconfig files, which is entirely self-contained
(except for the output and standard files folders) so an individual cave
can be easily moved to any other folder location and still compile with
little fuss.



Below, the INDEXTakakaValley.thc ties together all of the caves in the
project, and puts them on the same map. If two or more of the caves were
joined, then I would just create another INDEX file in the top level
project folder, eg INDEXBaigentsBreweryCaves.thc, and possibly matching
thconfg and layout files.





If you download the latest development version of Therion, you can use a
lookup to specify particular colours for each of the caves, as described
https://therion.speleo.sk/wiki/examples?s[]=lookup#colour_scales_-_lookups
 (half way down the page).

Re: [Therion] How to combine two maps

[Footleg via Therion]

Hi Bill,

I generally put just one .th file in my thconfig file, and that .th file
represents all the caves I want to process with that config. My master .th
file then includes the different .th files for different caves, and also
contains the equates to link them together (where they are joined by survey
data).

Hi Bill

I think you have the answers you need already, but I’ll add my two bits anyway.

I do almost the same as Ladislav.

Sounds like your caves are or should be part of one Therion project (simply 
because they are in the same general locality).  No need to change anything 
other than to make sure  all of the existing cave folders are collected 
together in a single project folder (as in the image below).

In the example below, my project folder is th_TakakaValley/trunk  (the /trunk 
is just an artefact of the version control system we use) and there are 7 caves.

The other folders are for outputs and standardised layout files.

I use a flat structure these days, ie each individual cave has its own folder, 
with INDEX*.th and thconfig files, which is entirely self-contained (except for 
the output and standard files folders) so an individual cave can be easily 
moved to any other folder location and still compile with little fuss. 

 

Below, the INDEXTakakaValley.thc ties together all of the caves in the project, 
and puts them on the same map.  If two or more of the caves were joined, then I 
would just create another INDEX file in the top level project folder, eg 
INDEXBaigentsBreweryCaves.thc, and possibly matching thconfg and layout files.

Re: [Therion] How to combine two maps

[Ladislav Blažek via Therion]

Hi Bill,

Three times yes.

But everything depends on your data/file structure.

For every cave I have one top level index file including all surveys and 
containing maps. When I want to merge related caves I would just create one 
upper level index th file including index files of relevant caves and define 
joins using equate commands.

For caves without direct connection you can define fix points.

Absolutely no way does it need to be redrawn, or the files moved. in
the map defintion of the first cave as add the map of the second cave,
maps can be nested and combined in many ways simultaneously

Yes more than one fix (gps) can be used, one gotcha to watch is if no
variance is specified on a fixed point they are taken as perfect and
not moved in the error distribution. With modern gps and a good signal
this is probably becoming close to true on the Northings and Westings,
but not always good for height

Yes I have loads of caves on the same printout in the Cheddar Catchment

Simply create higher survey in which you input all your caves and use it as 
source for export. 

This is on of main principles of Therion.
