Creative Workflows Using QGIS and SQL

Hayden Elza - February 2024

Whether you’ve been meaning to check out QGIS or SQL or you already have experience but want to see some unique use patterns and tricks, complete this workshop to build your own witness tree map using data from the original land survey of Wisconsin. Topics covered include filtered datasets, virtual layers, virtual fields, geometry generator symbology, label placement, adding database connections, database views, QGIS plugins, and spatial queries in Postgres. If you are familiar with QGIS or other GIS software, you should be good to go; no prior knowledge of SQL or topics mentioned earlier required.
