Real in person Meeting !
Karsten Vennemann will talk about map feature styles in QGIS. E.g. how to create a style library, create legend icons/shapes, how to share styles, and will also take a brief look into the QGIS ‘style generator’ awsomeness.
Karsten will also share his experimental work on trying to produce better hillshades for cartography purposes inspired by wanderingcartographer . We can have an open discussion about tools and approaches others are taking for hillshades …
Anyone interested is invited to share (their own or news about any interesting) small or large geospatial projects. As always any geo-questions are encouraged and will gladly be discussed within the group.
We will disucss plans for hosting a Spring Fling (mini conference) event in April 2023, and plan ahead for our next meetings .
@you Introduce yourself! Or re-introduce yourself! Please tell us about something cool you are working on, playing with, or otherwise inspires or puzzles you. Add yourself here. or reach out to us firstname.lastname@example.org
We had a nice meeting and great social geobeers afterwards. This feels great that after a 2 year hiatus and despite bad air (smoke from wildfires) 10 people showed up for the meeting !
Styles in QGIS
Create a style library and How to share styles
-> QGIS -> Processing Tools -> “Create style database from project” Tool , results in xml file with all styles in the project that can be imported in style manager
Create legend icons/shapes
-> QGIS -> Style Manager -> Legend Patch Shapes , can add WKT as legend icon patch in WKT format
QGIS ‘style generator’
This is a style that can be applied to layers and can generate and alter geometries for visual display
QGIS projects with data and examples zipped
