This repository contains scripts for comparing road network datasets from OpenStreetMap (OSM) and an authoritative source. The repository contains two folders:

• GRASS-scripts provides three Python modules to perform the complete dataset comparison in GRASS GIS
• WPS_OSM-REF-Comparison provides the code to setup the Web Processing Service (WPS) for a preliminary comparison of the datasets

Detailed instructions on how to use the tools are provided in each of the two folders.
