[Therion] Экспорт в KML - export cave-list html and kml

Thankyou Vlad, makes me feel like I’ve finally made it!  You’ve tricked me into starting a wiki post, in the FAQ page.

Right, your BTW made me think to look in the Therion Book (if all else fails, read the instructions).

Page 17 clears up the mystery of when Therion assumes a ‘cave’ if none is defined, but I think there are other cases.

 

All this looking at cave-list has made me realise I have been defining caves in the wrong place, the lowest level trip surveys.

I should be defining them in the next level up, the cave surveys – obvious really.

I will play with that for a bit, and I am hoping it does not change the behaviour.

Very good test and illustrations. You are my Therion guru :)

Using both markings seems to be a good way to separate the "cave" (main entrance marked on the survey command) from the secondary entrances (marked with station commands), and to switch the secondary ones on/off in the lists.


​Btw​, if you use -surveys off it hides the entrances, but only if you have defined a "cave main entrance" in the survey. If there is no main entrance, it still shows all the secondary ones defined with station.

 

Would you have the time to put your description and screenshots in the wiki? This is good information have.

I was wrong, export cave-list -fmt kml does report the full hierarchy, and may even behave better than the html output.

But it is a bit complicated – I did some testing…

 

Using this general form of survey definition…

survey 01 -title “Some Cave name” -entrance 1  

#defining the entrance here as part of survey definition tells Therion ‘it is a cave’

  centerline
    cs lat-long
    fix 0 11:22:33.4 22:33:44.5 1234  # set the GPS coordinates and elevation of station 0
    station 3 "Some other entrance name" entrance  

      # Mark station 3 as another entrance of ‘Some Cave name’ cave, and display it’s name also 

    …

  endcenterline

endsurvey

 

And using these exports….

 

#html

export cave-list \

  -surveys on   \ # on = show survey, cave hierarchy, & entrances so long as location is on, 

                  # off = show caves only, not entrances, no hierarchy

  -location on \  # on = show cave coords, and entrance coordinates only if surveys are on

                  # off = no coordinates

   -output ./Output/RiwakaSystemCaves.html 

 

#kml

export cave-list \

  -surveys on   \ # on = show survey, cave & entrances hierarchy

                  # off = show caves only, not entrances, no hierarchy

  -location on \  # on|off = no difference

   -output ./Output/RiwakaSystemCaves.kml   

 

Some examples using variations of the above.  In outputs below there are four caves explicitly defined; H-Hawkes Cave, Hawkes Kairuru Middle Cave, Kairuru Cave, Kairuru 3030.  And one cave that Therion has deduced as it is implied by the survey structure; Ngarua cave, Takaka Hill.  (Unfortunately I have not been disciplined with naming, so apologies that it is confusing). 

 

“Kairuru 3030” is defined as a cave, and it has two entrances defined in the centrelines (that are therefore part of Kairuru 3030 Cave, which has three entrances in total).

It is one of many caves in a Therion project that the outputs below are taken from.

Here the word ‘cave’ is used to mean the main entrance (ie ‘cave’ is an entrance and a cave, whereas ‘entrance’ is just an entrance that is usually a part of an already defined cave).

 

HTML Outputs

 

Html surveys on location on (the survey, cave and entrance hierarchy is shown.  Caves have a length reported, entrances do not)



 

Html surveys on location off (the survey and cave hierarchy is shown, but not entrances*.  Caves have a length reported, entrances do not)



*  Could this be a bug? Maybe, maybe not.

The last two records ARE entrances, but they have no survey legs associated, they are gps fixes only.  Maybe that is why Therion treats them differently and displays these but not others. 

Therion has used the survey hierarchy to infer it is a cave called “Ngarua Cave, Takaka Hill” even though there is no cave entrance defined in the survey definition.

 

Html surveys off location on (No hierarchy, caves only, no entrances – except fixed entrances, has coordinates columns)

Html surveys off location off (No hierarchy, caves only, no entrances – except fixed entrances, no coordinates)



 

KML Outputs

 

Kml surveys on location on (the survey, cave and entrance hierarchy is shown.  Does not distinguish bottom level records as either cave or entrance, could be either)

Kml surveys on location off (same)



 

Kml surveys off location on, 

Kml surveys off location off (both look the same, both contain coordinates - kml would be boring without locations!)



 

Hope that helps :)

Yes it does make a difference. Define a cave with the survey definition. Define secondary entrances within centrelines.

See the difference if you export caves to a html file. For best effect you can do this for a multi cave project where each cave has multiple entrances.  I will post example outputs later.

I suspect the kml exports are not reporting the hierachy however.

Yes, that's right, you can define any number of entrances like this.
Although I admit I haven't used the "survey 01 -title “Some Cave name” -entrance 1" syntax. So far I have always listed the entrances within the surveys with several  "station XX "Some other entrance name" entrance" lines.


Does it make a difference which syntax is used?

There are more subtle nuances that can be conveyed.

Have a look at https://therion.speleo.sk/wiki/drawingchecklist?s[]=entrance#points <https://therion.speleo.sk/wiki/drawingchecklist?s%5b%5d=entrance#points>  and scroll down to ‘Passage Ends’ point entrance.

You can tell Therion to define a cave, and further, specifically define all the entrances that the ‘cave’ has.

 

To expand on and change Vladimir’s example

 

survey 01 -title “Some Cave name” -entrance 1  

#defining the entrance here as part of survey definition tells Therion ‘it is a cave’

  centerline
    cs lat-long
    fix 0 11:22:33.4 22:33:44.5 1234  # set the GPS coordinates and elevation of station 0
    station 3 "Some other entrance name" entrance  

      # Mark station 3 as another entrance of ‘Some Cave name’ cave, and display it’s name also 

    …

  endcenterline

endsurvey

Have I got that right Vlad?

Hi

My Russian is not that good, so I will reply in English.

The kml model can export the entrances, if that is what you mean by "объектов". To get the name of the cave to display, you have to mark one or more stations as entrances. Something like this:

  centerline
    cs lat-long
    fix 0 11:22:33.4 22:33:44.5 1234  # set the GPS coordinates and elevation of station 0
    station 0 "Some cave name" entrance  # Mark station 0 as an entrance and set the name to be displayed. Not necessarily the same station as the one with the coords.
  ...

Здравствуйте.  Подскажите, пожалуйста. Я пытаюсь экспортировать данные
в KML-файл. Вот строка

export model -fmt kml -output Kungur_Z.kml

При   просмотре   kml-файла   он   не  отображает названия объектов, а
отображаются только линии.

Подскажите,  пожалуйста, как сделать так, чтобы названия объектов тоже
отображались?
