Offene Quelle¶
Offene Quelle ("open source" and "open spring") is developing a low-cost, open-hardware drinking fountain that mounts on standard fire hydrants. It can serve as a pop-up fountain during heatwaves and events, or as a permanent installation.
This site documents the potential analysis and the map behind it: how data layers are defined from OpenStreetMap, what each layer contains, and which rules and assumptions shape the result.
Prototype
The layers use public OpenStreetMap data only. All classification rules are working assumptions that haven't yet been checked with the water utility, fire brigade or authorities. Each layer's page lists its rules and assumptions.
Contents¶
| Page | What it covers |
|---|---|
| Layers | Every exported layer: attributes, rules, assumptions, sources (generated from the data directory) |
| Architecture | openwater, the layer format, the viewer and the data directory: who owns what |
| Writing layers | How to define and export a layer in a small Python script |
| Layer format | The interface: what a layer package contains (layer.json, data.geojson) |
| Viewer | Picking and styling layers in Settings, style format, edit access |
| Data sources | Catalogue of official and open sources for Kiel / Schleswig-Holstein, with licenses |
| Potential analysis | Method: M1 hydrant locations, M2 regulation, M3 water quality, M4 demand and gap, M5 scoring |
| ML feasibility | Can machine learning add missing hydrants and siting attributes? |
| Deployment | Running everything locally, services and data directory |
| Production deployment | Public server behind a reverse proxy: setup, checks, updates, backups |
