Green space, impervious surfaces and flood risk: Warsaw and Powiśle in QGIS
Exercises from my GIS course at the University of Warsaw: four environmental indicators for Warsaw and Powiśle, and the buildings inside Powiśle’s 500-year flood zone.
Maps and spatial data work with R and QGIS: what each piece shows, how I made it, and what it taught me.
I came to cartography from environmental impact assessment, where every report starts with a location map and a baseline. This page is where I practise in the open: making maps, and the R work behind them — finding and cleaning spatial data, joining it to environmental indicators, and turning it into figures that answer a question. Small pieces first, more ambitious ones as my R and QGIS skills grow.
