Nolli Plan Generator
A free web application for creating Nolli plans and urban maps from OpenStreetMap data.
Nolli plans (figure-ground maps) are essential tools in architecture and urban planning, required for most competitions and perfect for quickly understanding urban morphology. Despite their importance, obtaining these plans is often challenging - they're either expensive, restricted to official authorities, or simply don't exist for many locations.
SWZPLN.de solves this problem by creating free Nolli plans and additional maps using openly available datasets from around the world. The platform enables architects and urban planners to generate plans for any location with just a few clicks, offering multiple export formats including AutoCAD, PDF, and SVG.
Key features:
- Free and open access to plan data worldwide
- Multiple export formats (AutoCAD, PDF, SVG)
- Customizable layers (buildings, green spaces, water bodies, roads, railways, height contours)
- Privacy-focused: all data processing happens locally on your device
- Open-source code for transparency and community development
The project emphasizes digital justice by making plan data freely available globally, not just for European and North American cities. By processing data locally on users' devices, we ensure privacy and minimize server resources.
