As traditional infrastructure design methods migrate from 2D to 3D modeling, this presentation will review a process designed to integrate 3D design models with 3D existing condition models. There will be focus on the challenges in the practical application of the federated model concept with specific attention to the risk and liability associated with the process. In this presentation the presenter will then define the mission of the geospatial team and how it can be effectively integrated within the iTwin process to overcome these shortcomings. Finally we’ll look at the new TopoShare™ Geospatial Data Catalogue and how it serves a critical role in the execution of a comprehensive process iTwin process. The presenter will discuss other data storage/sharing/viewer products on the market, present their advantages and shortcoming as well as their role in the overall process. The utility of TopoShare™’s unique ability to effectively communicate every instance of geospatial project data across downstream operations will be introduced. This communication makes possible the documentation and maintenance of quality standards of federated reference models in support of the iTwin centered design process.
