Smart 3D City Models for Planning, Analysis and

10th - 11th October 2018


The Forum Digital City is a joint event of VirtualcitySYSTEMS GmbH and CADFEM GmbH.
Both companies are 100% part of CADFEM Group.

We develop smart city solutions towards a “digital twin” of cities, urban districts and buildings based on many years of experience in the field of geoinformatics (VirtualcitySYSTEMS) and numerical simulation of physical behavior (CADFEM). The “digital twin” based on CityGML (existing buildings), BIM (new buildings) and OpenDRIVE (road space) makes it possible to plan new projects, monitor construction and lifecycle processes, to investigate what-if scenarios and to find sustainable solutions for the complex urban challenges of our time.

The Forum brings together an international group of specialists, pioneers, researches and planers, from business and municipalities. They share their solutions, experiences and challenges, exchange innovative ideas and discuss solutions for the City of the Future.

“CityGML is an open standardized data model and exchange format to store digital 3D models of cities and landscapes. It defines ways to describe most of the common 3D features and objects found in cities (such as buildings, roads, rivers, bridges, vegetation and city furniture) and the relationships between them. It also defines different standard levels of detail (LoDs) for the 3D objects, which allows the representation of objects for different applications and purposes, such as simulations, urban data mining, facility management, and thematic inquiries.”

“OpenDRIVE is an open format specification to describe a road network's logic. Its objective is to standardize the logical road description to facilitate the data exchange between different driving simulators. They do not describe the entities acting on or interacting with the road.”

“BIM involves representing a design as combinations of "objects" – vague and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), that carry their geometry, relations and attributes. BIM design tools allow extraction of different views from a building model for drawing production and other uses. These different views are automatically consistent, being based on a single definition of each object instance."
