Get started with urban analytics in Python following my new course:

1 · Setting Up — The study-area pattern the whole course runs on: one place name resolves to an administrative boundary, and everything clips to it. Change one string, and the analysis re-runs on a new city.

2 · Acquiring Urban Data from OSM — Boundaries, cafes, parks and footprints, pulled from OpenStreetMap by tag. Pull a generous bounding box, then crop it to the exact shape with a spatial join.

3 · Buildings — Every footprint via one query, the messy tag table screened down to what's actually populated, mapped by function, and measured in real square metres. (And why a footprint isn't floor space.)

4 · Road Networks — The city as a graph of intersections and segments. Drive vs. walk networks, structural hubs, segment-length texture, and road-class hierarchy.

5 · Basemaps, Projections & the Urban Profile — Real basemaps, the declare-vs-reproject CRS distinction every measurement depends on, and every layer composed into one urban profile — then swapped Vienna → Budapest unchanged.

6 · The Livability Index — All 23 Vienna districts. Ten OSM KPIs across five dimensions, normalised and weighted into a single rankable, mappable score — with every assumption on the table.

Our Let Girls Map Campaign took to the field last Friday to put mobile mapping into action across the UCC campus. Using the Every Door app, we mapped critical streetlights and road signs to improve campus safety and navigation.
We don't just build maps, we build mappers!
