OSMnx
The OSMnx tab downloads and analyzes real-world street networks from OpenStreetMap. It exposes the full OSMnx toolbox — download, projection, routing, accessibility, statistics, features, and elevation/terrain — adapted to the Blender environment.
The root OSMnx panel is a status header: once a graph is imported it shows the active network’s name, node/edge counts, place, and CRS. Most subpanels require an imported OSMnx graph and display a hint pointing to Download until one exists; subpanels appear in workflow order.
Panels in this tab
Each panel of the addon has its own reference page:
| Panel | What it does |
|---|---|
| Download | Import a street network by place, point, bbox, polygon, or XML. |
| Graph Operations | Project, convert, simplify, consolidate, and truncate the graph. |
| Network Attributes | Add edge lengths, bearings, speeds, and travel times. |
| Routing & Paths | Shortest path, K alternatives, and batch many-to-many routing. |
| Accessibility | Isochrones, ego subgraphs, and network DBSCAN. |
| Statistics & Centrality | Basic stats, circuity, centrality, orientation, node-pair distances. |
| Features & POIs | Download OSM features, snap POIs, and geocoding/geometry helpers. |
| Elevation & Terrain | DEM sourcing, 3D positions, grades, terrain mesh, and basemaps. |
| IO / Export | GraphML round-trip, GIS export formats, and the graph cache. |
Header status fields
When an OSMnx network is active, the header reports:
| Field | Meaning |
|---|---|
| Network | Name of the active graph object. |
| Nodes / Edges | Node and edge counts. |
| Place | The query/place name used to download it. |
| CRS | The coordinate reference system (only shown once projected). |
Typical workflow
- Download a network by place, point, or bbox.
- Project to CRS in Graph Operations, then add Lengths, Speeds, and Travel Times in Network Attributes.
- Use Routing, Accessibility, and Statistics & Centrality for analysis, mapping results to attributes.
- Add Elevation & Terrain for 3D context and a basemap, then visualize and render via the SciGraphs Visualization panel.
- Export or cache the result.
