VC Suite Urban Digital Twin and VC Map

virtualcitysystems GmbH was founded in 2005 in Chemnitz and is now registered in Berlin, Germany. It supports cities, municipalities and infrastructure operators in building and using 3D city models and urban digital twins for planning, citizen information, climate strategy and crisis management.

The VC Suite combines VC Database and VC Warehouse for managing semantic 3D city models (CityGML), VC Publisher for preparing and publishing 3D data, and the browser-based VC Map for viewing and analysing models, oblique imagery, meshes and specialised data on any device. Extensions add planning (VC Planner), solar potential (VC Solar), panoramas, storytelling, XPlan development plans and simulation such as VC Blastprotect for WWII bomb detonation zones. BuildingReconstruction creates 3D buildings from point clouds and footprints. References include Helsinki, Bremen, Rotterdam, Kassel, Lörrach, Arnsberg and Frankfurt.

• VC Map: Web viewer for 3D city models, meshes and oblique imagery with measurement and analysis tools.
• VC Publisher: Prepares and publishes 3D data and maps for web portals.
• VC Database and Warehouse: Manage and version CityGML-based 3D city models.
• BuildingReconstruction: Generates 3D buildings from point clouds and footprints.
• VC Planner and VC Solar: Embed planning designs and calculate rooftop solar potential.
• Urban simulation: Models what-if scenarios such as blast zones, climate events and mass gatherings.

A Vietnamese city department can publish a public 3D portal showing approved development plans in context. A GIS integrator can automate 3D building reconstruction from LiDAR for a provincial 3D cadastre. An energy agency can map rooftop solar potential across districts using VC Solar.

Browser-based measurement, height profile, visibility and shade tools reduce time-consuming on-site inspections. Public 3D portals let citizens see how planned buildings fit their surroundings, improving transparency in approvals. Automated updates keep the twin current; Helsinki detects nightly changes in its 2D building database and pushes them into the 3D model automatically.

Urban digital twins built on open standards such as CityGML and 3D Tiles are becoming part of planning administration in Europe and Asia. Vietnamese cities such as Da Nang plan digital twin pilots for urban planning management, creating demand for proven platforms that manage 3D city models and publish them to officials and citizens.
