Build A Routing Web Application With OpenStreetMap, Neo4j, & Leaflet.js

Using GitHub Codespaces is the recommended way to create a Python development environment for this workshop.

Step 1: OpenStreetMap Data Import With OSMNx

First, create a Neo4j AuraDB instance.

Then use this notebook to import OpenStreetMap and address data into your Neo4j instance.

Step 2: Leaflet.js Web Map

This file contains HTML and JavaScript for a simple address search and routing web app. Edit the file to connect to your Neo4j AuraDB instance.

We're using Dijkstra's algorithm for routing - can you improve the routing query using the A* algorithm?
