Advanced QGIS Expressions

Ujaval Gandhi, Spatial Thoughts
The QGIS Expression Engine is very powerful that allows you to apply your custom logic to geometries, attributes, labels and much more. This talk will cover advanced expression techniques that allow you to do complex geoprocessing and automate manual data entry tasks without custom coding or plugins. The talk will show how you can setup your project to automatically fill attributes based on relationship with other layers, do fuzzy table joins, calculate shared border lengths between polygons and automate data QA.

Aprendí mucho más en este video que en todos los cursos "avanzados" que he llevado. Y eso que de inglés apenas se los números y colores xD. Excelente profesor.
