The VISTA project aimed to integrate utility data from various UK organizations to improve coordination and reduce costs of street works. It developed methods for syntactically and semantically integrating heterogeneous utility data through a common data model and global thesaurus. Visualization techniques were also explored that incorporated uncertainty and were driven by an ontology. While the project proved the concept, further work is needed to develop the ontology and address implementation challenges regarding data currency, security, and impact on organizational systems.
