[Qgis-user] Colouring Geological Maps

[Richard McDonnell]

Morning,
I'm not sure if this is a solution for you, but have you considered using attribution and storing your styling requirements as a set of attribute values. You can do this for Fill Colour, Stroke Thickness, Font, Sizes...etc...
You could build a graphic modeller to add the attribution to your data and then have a single default style, which has all the Styling Variables set to use the new attribution.
The only issue with this is that you won't generate a legend...
Kind Regards,

Richard

Subject: [Qgis-user] Colouring Geological Maps

I am trying to find an easier way of colouring a geological map. The only way I can find to colourise the polygons in both the map window and layers panel - and hence the displayed legend - is to use the rule-based rendering option. Each rule has to be manually styled.

Is there a way to get QGIS to interrogate a text file for styling information? I can't seem to find one anywhere in the algorithms. Aiming to use this in a graphical modeller to automate colourising geological maps. I can use a fixed qml file but that has to be done for each individual map unless you have a wide range of set styles.

Cheers Grant, Perth WA
