Region spotlights
Zoom into design hubs before you download a single file
Each spotlight blends planning cues, ecology priorities, and municipal quirks.
Stuttgart Metro
High slope gradients + mobility corridors demand paired hydrology + transport data. Start with LGL terrain models and Verkehrsentwicklungsplan.
Freiburg Region
Ecology-first planning: cross-reference Natura 2000, forest research (FVA), and municipal tree lists before concept review.
Upper Rhine
Floodplain considerations + cross-border policy mean hydrology + procurement datasets are mandatory for early diagrams.
Methodology
How we vet sources
We focus on government portals, academic labs, and long-running monitoring programs. Every entry is reviewed for freshness, licensing, and spatial resolution before it goes live.
- ✅ Confirm publisher authority and citation requirements.
- ✅ Note spatial resolution & update cadence for design decisions.
- ✅ Link directly to canonical download or service endpoints.
