City2Graph · Import urban data

Overture buildings and places, local GIS files, and GTFS feeds for Burjassot. Mirrors the Data Import panel.

To align downloads with an existing street network, keep an OSMnx network active and use From OSMnx as the area method.

1. Define the area

The simplest Define Area option is Place with Burjassot, Valencia, Spain. From OSMnx, Point, Address, BBox and Polygon reuse the OSMnx area fields.

2. Download Overture features

Toggle the layers you need (building, segment, place, water, land) and set a Limit. Get as Mesh brings in footprints; Get as Points creates point nodes directly.

Selecting Overture layers and downloading.

3. Convert to centroids

Reduces polygon footprints to one point each, which is the node representation proximity graphs expect.

4. Load a local file

Load File takes a GeoPackage, Shapefile or GeoJSON of your own zones or features.
