I am Spatial Science Teacher at TAFE NSW teaching Spatial Information Systems online. In 2019 our department started including links to many of the Spatial Query Lab SQL lectures in our resources. We found them to be excellent as they were software-neutral and pitched lots of GIS concepts at just the right level for our students who need theoretical information at a simpler level than many university level texts. The Labs for these classes are available here: https://github.com/FOSS4GAcademy/GST102FOSS4GLabs but not the lectures.
Does anyone know how to contact Rick Smith (previously at [email protected]) or anyone who might have a copy of these lectures?
