Shortest Path Routing with PostGIS - PGRouting - Network Analysis - Complete Web Project - Part 1
In this first part of the series, we lay the foundation for building a routing system by preparing the road geometry for network analysis.
Read MoreIn this comprehensive tutorial, we demonstrate how to integrate pgRouting with PostGIS in QGIS for powerful network routing analysis. You'll learn how to set up a routing model on a PostgreSQL/PostGIS database from scratch and then use QGIS to visualize the shortest path between two points on a map. We walk through each step of importing your road network data, enabling pgRouting functions, and performing route calculations directly within QGIS's user-friendly interface. This hands-on demonstration shows how QGIS can serve as a front-end for robust, database-driven analysis by highlighting a real example of finding the fastest route from point A to B.
In this first part of the series, we lay the foundation for building a routing system by preparing the road geometry for network analysis.
Read MoreIn this second part of the series, we focus on creating the node layer — a crucial component of any routing system.
Read MoreIn this crucial step, we bring our routing graph to life by generating edges — the paths between network nodes. These edges represent the segments vehicles will travel, along with distance-based cost values needed for shortest path calculation.
Read MoreIn this powerful episode, we finally plug in the brain behind our routing system — the pgRouting extension — and execute our first shortest path query using the Dijkstra algorithm.
Read MoreIn this final technical part of the routing series, we make our shortest path engine dynamic and ready for real-time use — by using input points and materialized views.
Read MoreIn this final part of our GIS routing series, we bring everything together into a fully functional Web GIS application. Using Leaflet.js for frontend, GeoServer for WMS rendering, and PostGIS + pgRouting for backend logic, we built a real-time, interactive shortest path routing system.
