[Qgis-user] FGDC Geology Symbols

Sun Oct 12 15:26:45 PDT 2025

Hi Riaan,

The USGS symbol set can be downloaded from the QGIS resource sharing
plug-in. 

The USGS geological patterns can be downloaded the same way, just need to
add an additional repository -
https://github.com/BC-Consulting/FGDC-4-QGIS,git.

Regards Grant

Hi,

I cannot reproduce this on my systems.
I reckon that you have a HDPI screen on windows, and searching at the
issuetracker on "font size" several issues pop up, eg
https://github.com/qgis/QGIS/issues/63065

Are you able to create an issue on
https://github.com/qgis/QGIS/issues
to provide more information about your exact setup, and ways to reproduce
this?

Note that QGIS 3.x is based on Qt5 and this kind (hi res) setups wasn't
around at that time.
I know that there has been a lot of work on font-scaling and handling hdpi
by Nyall.

Would it be possible for you to install the experimental latest version of
QGIS, which is build on Qt6:
https://qgis.org/downloads/QGISQT6-OSGeo4W-3.40.11-1.msi (thinking you want
LTR) or maybe even latest:
https://qgis.org/downloads/QGISQT6-OSGeo4W-3.44.3-1.msi
and do some testing with those?

If these still have issues then please(!) create issues because then even
the latest and greatest version needs love and work...

Regards,

Richard Duivenvoorde

Good day,

I am looking for the FGDC (Digital Cartographic Standards for Geologic
Symbolization) symbology that is compatible with QGIS.

There are some available in various websites (bits & pieces) but I require
the full set. The email on their website just bounces back.

Help? Ideas? Suggestions?

Riaan

Hi,

I had similar problem few months ago, and I believe it was related to
creating project in newer version of QGIS (3.42) and then continuing working
in older version (3.40).
My solution was to create entire project from scratch in lower version and
then it was everything OK. I think that even if you open project once in
newer version and save it without making any chages it could mess things up
with printing/exporting from layout.

Hi,
thank you very much for your reply. One thing I have noticed is that in the
project there are layers taken from the Internet by the Swiss Federation.
if I export with the pc disconnected from the internet, it works. But
obviously the layers that it should recover from the internet are missing.
Has it ever happened to you? among other things, I am doing the tests
connected to a network cable with a very fast business connection if I am
not mistaken it goes to 10 Gb/s.

Thanks a lot and have a good continuation Matthew

Subject: [Qgis-user] Percentage of area overlaped / covered by feature
	of another layer
Message-ID:
	<CAHByMH0Dkw+wGqAPMjV_1urue+jTBGhsaEzic0A7znReHg_Q7A at mail.gmail.com>

Dear all,

I'm working with QGIS and, if necessary, PostGIS.
I have two vector layers :

 - A first polygonal layer resulting from vectorization work using
photointerpretation of the aerial imagery (in blue in the attached
screenshot below).
 - A second polygonal layer in the same area resulting from segmentation of
the same aerial imagery (in yellow in the attached screenshot below).

[image: unnamed.png]

Each feature in the two layers has a unique identifier (representing thanks
to labels in the screenshot).

I'd like to be able to produce a small performance indicator of the
segmentation performs in faithfully matching the photointerpretation. I was
thinking there's probably something that could be done with geoprocessing
(union, intersection?) and a area calculation ? An indicator of segmentation
performance could be: for each photo-interpreted feature/polygon, calculate
the percentage of the surface area covered by the feature in the
segmentation layer with the biggest overlap ?
To be more specific, in the example screenshot, this could be:
"For feature 11 in photo-interpretation layer (blue), I would like to know
the percentage of the surface area covered by the feature in the
segmentation layer that has the highest overlap with this feature 11 (in
this specific case, it's probably feature 42 in yellow)."

This could be: area of feature 42 overlapping feature 11 / total area of
feature 11?

I don't know if I'm on the right path. How could we translate/reach this
needs toward a QGIS and/or PostGIS tool?

Thanks so much
