HS2 is the biggest engineering project in Europe and of our time. Xerini were delighted to provide expertise to help the organisation manage their complex data integration requirements. We set about simplifying the processes and architecture and moving to a more flexible, open-source-based solution that gave their analysts and managers full control and visibility of the data. We also built a reliable and extensible system that provided them with a means of getting on top of their data quality problems. Furthermore, our advanced mapping techniques and visualisations have helped HS2 personnel to easily search, locate and cross-reference their data sets.
