OSMnx · Save, export and cache

Persist the Burjassot network as GraphML, export it to GIS formats for external tools, and reuse downloads through the cache.

This walkthrough mirrors the Import/Export panel.

Before you begin

Have a downloaded network active (see Download a street network).

1. Save and load GraphML

Set the GraphML Path and press Save GraphML to write the network in OSMnx’s native format, preserving all attributes. Press Load GraphML to read one back in.

Saving the network to GraphML.

2. Export to GIS formats

Set the Export Format — GeoPackage, OSM XML, GraphML (Gephi) or SVG — and press Export. GeoPackage is ideal for QGIS; GraphML (Gephi) for network-analysis tools.

Choosing an export format.

3. Use the cache

Press Save to Cache to store the full graph object on disk. View Cached Graphs lists what is available, Load from Cache restores one instantly, and Open Cache Directory reveals the folder. This avoids re-downloading the same area.

The graph cache controls.
