First sentence: When I started teaching GIS at IHE Delft Institute for Water Education in 2012, there were not
many courses that used open source software. Given that our MSc participants are mostly
from the Global South and can’t afford expensive licenses, I wanted to change that for my
GIS classes. QGIS was the logical alternative, which has all the features my students need for
their work in hydrology and water management. In the recent versions, new features have
been included that go far beyond what commercial GIS desktop software offers.
