Editable topologies in pgRouting
06-29, 14:30–15:00 (Europe/Tirane), UBT D / N115 - Second Floor

pgRouting, a PostGIS extension containing algorithms and tools for working with graph data, has become a highly flexible member of the FOSS routing engine family. In this talk, I want to demonstrate just how flexible it can be by showing how routable networks (called 'topologies' in pgRouting) can be made editable.

I will take the audience from theoretical conception of editable topologies (how can edits, insertions and deletions be handled in PostGIS?) through its implementation. Finally, I will end with a demonstration of a fully editable topology in a web mapping application based on a real world example using OpenStreetMap data.
