City2Graph · Analyze metapaths

Connect Burjassot amenities through the street network using metapaths: build a street dual graph, bridge amenities to segments, and materialize amenity-to-amenity relations by hop count or by weight.

This walkthrough mirrors the Metapath Analysis panel.

Before you begin

Have a drive (or walk) street network and an amenities feature object active (see Import urban data).

1. Configure the analysis

In Metapath Analysis, set the Amenities Object, the K Neighbors (how many segments each amenity bridges to, default 1) and an Amenity Limit to cap large areas.

Configuring the amenities object and parameters.

2. Materialize by hops

Expand Materialize by Hops, set Hops (default 3) and press Compute Metapaths. This builds the street dual graph, bridges amenities to their nearest segments, and connects amenities reachable within that many segment hops.

Amenity-to-amenity metapaths within 3 hops.

3. Materialize by weight

Expand Materialize by Weight, set the Weight Attr (e.g. length), a Threshold and an optional Min Threshold, choose the Endpoint Type, and press Compute by Weight. Amenities within the cost band are connected using a Dijkstra search.

4. Inspect and visualize

In Result & Inspect, press Convert to Mesh to draw the metapath curves in the viewport, where edge multiplicity reflects how many distinct paths connect each amenity pair.
