Hi guys,
I can’t find a way to change the light greyish color of the kml export except by going into the kml file and change it after it has been created. Is there a way to specify the color when creating the kml ?
Thanks,
Phil
Dear all,
I am mostly writing to Therion developers, as I am not able to propose a valid code modification myself.
For a large project (Gouffre Jean-Bernard + Gouffre Mirolda, France), we are exporting the surveys as ESRI shapefiles to build a GIS. For that, we also are developing a style sheet to reproduce the Therion symbology inside QGIS. It permits us to have the complete survey database on our phones/tablets in the field as a GIS project (we are currently using Mergin Maps app with a custom server). For those interested in, please, see pages 89 - 95 of the report https://groupe-speleo-vulcain.com/wp-content/uploads/2024/03/2023_Rapport_E… <https://groupe-speleo-vulcain.com/wp-content/uploads/2024/03/2023_Rapport_E…> (in French).
But, there are some points that quite problematics/time consuming, and that may (?) be improved directly in Therion with the ESRI/shp export command:
for the shapefile points2d.shp, the Therion feature corresponding to the « -value » option is not exported. For us, this is a problem to render the point « height », as the value of the height does not exists in the shp —> If in a next Therion release the -value option could be added to the attribut table of the point2d.shp, it would be great!
in our GIS, we want to get the altitude information for at least station points. This information is not included in the attribut tables (points2d.shp and stations3d.shp). To get it, we have to reprocess the station3d.shp with a python script to add the altitude value in the attribut table after each new Therion compilation —> Is it possible to add the station altitude value in the attribut table directly from Therion shp export?
The lines and areas shapefiles produced by Therion export are not limited to the inside of the cave (i.e. inside of the outline), even if they have the -clip on option. We need to use a custom Python script to cut the lines and areas with the outline shapefile as a mask, and this is absolutely not tolerant even for a very minor topologic error. —> Is it possible to modify the ESRI/shp exportation function from Therion to natively masked the lines and areas that have the -clip on option and that are outside of the cave outline ?
Is that possible to implement these features in a future Therion release?
Thanks a lot,
Cheers,
Xavier
Dear all,
Some weeks ago, I commented the issue « https://github.com/therion/therion/issues/571 <https://github.com/therion/therion/issues/571> ( Suggestion to add new flags for survey shots) » on Github.
So far, I have not seen any answers, so I forward it there in case of someone is interested in and/or is able to update Therion with such a new feature:
I do not know if this is easy to code or not, but I completely agree with cctrunz, it would be very usefull also for me to add new flags for survey shots. I am interesting in "artificial", but also in something like "active meander"/"active gallery", "active phreatic gallery", "fossil phreatic gallery", etc.
One suggestion could be that somewhere (in centerline blocks? In a config file (better?)?), the Therion user could define its proper shot flags names with a syntax like:
def_flags "MyNewFlag" "MNF" where "MyNewFlag" is the name of the flag use in the command flags, and MNF correspond to the 3-letters string associated to this flag in the sql database (and in the ESRI/shp export?).
That means that some cases have to be considered:
• if the new flag definition exists and is used in centerline(s) --> update the database accordingly
• if the new flag definition does not exist and a new flag is used in a centerline: 1) raise a warning during the compilation indicating the presence of an undefined flag, and 2) update the shot database by adding a flag_name by default as "udf" (undefined?).
I will be very interested in that feature for large and long-lived network analysis purposes (i.e. extract only a certain type of conduit for instance). I am sure it will strongly extend the possibilities of Therion survey database post-analysis.
Thanks a lot,
Cheers
