1. Introduction

Abstract

pgRouting adds routing functionality to PostGIS. This introductory workshop will demonstrate the routing functionality by providing practical examples using OpenStreetMap road network data. It will be covering topics from how to prepare the data, make routing queries, write a custom ‘plpgsql’ functions up to draw your route in a web-mapping application. In other words, integrating pgRouting with other FOSS4G tools.

Navigation for road networks requires complex routing algorithms that support turn restrictions and even time-dependent attributes. pgRouting is an extendible open-source library that provides a variety of tools for shortest path search as an extension of PostgreSQL and PostGIS.

The workshop will focus on shortest path search with pgRouting in real road networks. It will cover the following topics:

• Installing pgRouting.

• Creating a routing topology.

• Using pgRouting algorithms.

• Importing OpenStreetMap road network data.

• Writing advanced queries.

• Writing a custom PostgreSQL stored procedure in ‘plpgsql’.

• Building a simple browser application.

• Building a basic map interface with OpenLayers.

Prerequisites

• Workshop level: intermediate.

• Attendee’s previous knowledge: SQL (PostgreSQL, PostGIS), Javascript, HTML.

• Equipments: This workshop uses OSGeoLive (Version 13.0)
