Re: [Therion] kml export is not working

[Torsten Schnitter via Therion]

Hello

I have stripped down all the data to the minimum.
You can find all attached in the zip file.

As far as I know you only need a geo reference within your survey network.
But you don't need to have a geo reference within your selected data for output.
Am I wrong with that?

Anyhow.
If you have a look at the "thconfig-survey.thc" file you can find some "DOES 
NOT WORK" and "DOES WORK" statements.
Beside this when not selecting anything it also does work with the kml export.
What also does NOT work is selecting all lines (wihat should be the same as 
selecting nothing).

When I do select the map "survey_southpassage_plan_m" it does work.
This map does have the same lines like the first part in the 
thconfig-survey.thc file which is not working.

May be there is something wrong in the select command?

regards,
Torsten

Re: [Therion] Colouring an elevation based on surveys that are not being displayed

[Bill Gee]

Hmmm...  OK, one more WILD idea:

Print the colored map as an atlas.  There are a lot of parameters that go into 
generating an atlas.  I suspect with some playing around you could get somewhat 
close to getting the portion of the cave you want on one page of the atlas.

>From there it is a simple matter to extract one page from a PDF file and make

I was not anticipating that anyone but you would need ImageMagick.  I thought 
the use case was that you would generate and distribute the image files, and 
everyone else would simply admire your handiwork!  :-)

Re: [Therion] kml export is not working

[Nick Bairstow]

Just got there before me John. You are correct no coords but there is not much 
else either. I can edit the kml and insert coords name and icon and the file 
opens as expected but no centreline/splays or map outline in the case of model 
output. Also, if you try to compile Therion and ask for kml output and there 
are no coords in the .th then it fails with a warning.
I think there is something else going on and we need to see all the data.

Hi Bruce,

obviously there was an error in the code, now it should work as expected.

Only selected maps are exported and maps offset can be turned off. Thanks

Re: [Therion] Colouring an elevation based on surveys that are not being displayed

[Tarquin Wilton-Jones via Therion]

> Would the colours for the specific altitudes not be fixed if you used
> lookup?

They would, but the intention was that - rather than having to manually
select all the colours to get the perfect graduation of colours (which
you have to do if you use a lookup table), you could get Therion to
automatically take the height from a map, since it already knows those
heights, and knows exactly how to colour those parts.

I had thought about using lookups, but it feels very clunky as an
approach, since it means manually specifying the altitudes of the
highest and lowest points - manual knowledge of automatically calculated
data.

With a lookup, you need to know exactly the colours it will have
selected for each height that matters. Each time a new piece of passage
gets added to the top or bottom of the cave, which then changes all of
the automatic colouring within the cave, you will have to re-calculate
the lookup colours again for use with your subset maps.

With "altitude-relative caveMP@cave" this would all become automatic.

Hi Tarquin,

Might be really oversimplifying but didn't you write a wiki page about this 7 
months ago? https://therion.speleo.sk/wiki/colouringelevations

With the use of Lookup at the bottom of the page?

Would the colours for the specific altitudes not be fixed if you used lookup?

Thanks for the suggestion.

For me, this is all very easy indeed, and if it were only me that
mattered, I would probably go down this route (as I have done with
wkhtmltopdf to get a modified cavelist into a survey). Even removing the
legend part is very easy with the various Therion options. But my
intention is to be able to share my surveys, source and all (they are
going to be one of the open source licences). Sadly, I cannot expect
another user to have to install and configure ImageMagick, and make
adjustments when adding new cave passage to a survey which shifts the
positions of things.

This is why I am hoping for a solution that works entirely within
Therion, if at all possible.

Still hoping for "altitude-relative caveMP@cave", which would be so much
easier for both my use case, and the use cases that I can see others
wanting :)

Re: [Therion] Colouring an elevation based on surveys that are not being displayed

[Bill Gee]

Regarding the map-image: As far as I know, Therion will not produce a JPG file. 
 However ...

It is quite easy to turn a PDF into a JPG, especially on Linux.  Once that is 
done, then any decent photo editor can crop it.  The legend will be a problem.  
I suppose you could crop out two sections (the legend and the cave portion you 
want) and paste them into a single image.

On Linux you need the ImageMagick package.  Most distributions include it as a 
base item.  With that you use the "convert" command:

convert -density 300 -rotate 90 infile.pdf outfile.jpg

-density sets the dots-per-inch in the output file.  -rotate rotates the image 
90 degrees before saving. 

Convert has hundreds of options  Spend some time with the man page.

There is a Windows version of ImageMagick.

[Therion] Colouring an elevation based on surveys that are not being displayed

[Tarquin Wilton-Jones via Therion]

Hi folks,

When you colour a survey by depth (color map-fg altitude), it colours it
based on the scraps that have been selected. This is normally useful.

When you produce an output with only one part of the survey (eg. a
zoomed-in section of a more complex part of the survey), however, it
would be more useful to be able to keep it the same colour as it was in
the larger survey, so that a viewer can quickly see which part of the
cave they are looking at, and see that the colours match. (My own
use-case is different, but the solution would be the same.)

Is there, for example, a way to say this:

layout local
  color map-fg altitude
endlayout
source "cave.th"
select subsectio...@subsection.cave
altitude-relative caveMP@cave
export map -proj plan -layout plan -o "cave.pdf"

Alternatively, is there a way to add scraps belonging to the highest
points and lowest points into the map, but not have them render, while
still being used for altitude colouring (this seems like a hack rather
than being a dedicated solution).

Alternatively (and I know this will seem a little out of place here, but
it is an alternative solution for what I need), is there a way to import
a map-image, and crop it to only include a portion of the image?

Cheers!

Re: [Therion] kml export is not working

[Nick Bairstow]

I am using 5.4.4 as well but on Win 10
I use:
export model -o Output/PathToYourCave.kml

This works fine for me. Adding -fmt kml to the line also works. To be honest I 
am struggling to break it unless I do something very wrong. Do you get a 
warning when compiling? It is strange that you get an output but it seems to 
contains nothing. I have spent a short while attempting to mirror that with 
some of my data that but have failed.
Do you get the same result with export map -fmt kml?
Without seeing all your data all we can do is to try and break ours which is 
perhaps not the best way to find an answer.
Hopefully someone will have seen this behaviour before and know what is wrong.
I will try again later.
