Compass Informatics [1] is pleased to announce the open sourcing of its routing library Wayfarer [2][3].

Wayfarer is a pure Python library that allows spatial features to be loaded into a NetworkX [4] network format. Once in this format the data can be manipulated and analysed using the huge range of graph algorithms in NetworkX.

The Wayfarer library provides a number of helper functions for example to calculate routes, split edges, find ends of paths, and retrieve features by keys.

The talk will outline the use cases for the library, and when it may be suitable to use rather than alternatives such as pgRouting. Case studies will be presented including Wayfarer’s use in Ireland's Pavement Management System to help designate works and surveys on the road network. Wayfarer is also currently used for an Environmental Protection Agency project to create fully connected river networks in Ireland.
