[Qgis-user] FGDC Geology Symbology for QGIS

[Torsten Lange]

Thank you, Stefan,

I expected the import function for the *.xml files also in the layer style setting dialog. It's in project settings, now I know.

However, I have format problems related to the various line definitions for folds, faults etc. I see a lot of question marks. Is there something I have to do in addition?

 Hello Torsten,

 You can import new symbology via the Style Manager, using the Share 
 button and then the Import choice. That allows you to navigate to 
 wherever you put the various relevant .xml files (in the FGDC geology 
 case, these are the contacts.xml, faults.xml, folds.xml, and 
 joints.xml): it does not really matter where you keep these files (my 
 personal preference is to have a dedicated qgis_projects folder in which 
 I can assemble and organise projects as well as any support files I feel 
 I may need).
 Once the symbology has been imported, it will be available for any 
 project you care to pursue.
 Best wishes,

 Stefan

 Hello Lester,

 If I understand you correctly, then the reason you do not see dashed or 
 dotted lines is because they are too fine to be visibly rendered by 
 qgis. When you generate a map, these lines will be visible in the pdf, 
 tiff, or other output you chose.
 When compiling the symbology, I discovered that qgis is not sufficiently 
 precise with the thickness, lengths and separations between dashes. As a 
 result, I defined a number of svg lines so that the distances and 
 separations defined in the FGDC standard could be implemented. That is 
 also why I have included the various .xml files: these combine the 
 relevant .svg symbols and line segments into the hopefully correct FGDC 
 symbol.
 Best wishes,

 Stefan
