OSMnx · Compute statistics
Compute morphometric statistics for the Burjassot network, measure circuity and centrality, and analyze street orientation with an entropy value and a polar rose.
This walkthrough mirrors the Statistics panel.
Before you begin
Download and project a drive network (see Clean up the graph).
1. Basic statistics
Press Estimate Area to compute the network’s spatial extent, then Basic Stats for node/edge counts, average degree, street density and total street length.
2. Circuity
Press Circuity to report the ratio of network distance to straight-line distance. Values near 1.0 indicate a straight, grid-like layout.
3. Centrality
Set Kind to Betweenness (node), Betweenness (edge) or Closeness, toggle Weighted, and press Centrality. Results are written as attributes you can drive colors from.
4. Orientation entropy and rose
Make sure bearings are present (Add Edge Bearings, see Add edge attributes). Press Orientation Entropy for a single value — higher means a less grid-like, more organic layout. Then press Orientation Rose (using the Rose Bins field, default 36) to build a polar histogram of street directions.
