CITY GML AND BIM

15th - 16th November 2017

6. FORUM DIGITAL CITY

The Forum Digital City is a joint event of CADFEM GmbH and VirtualcitySYSTEMS GmbH. Both companies are 100% owned by CADFEM International GmbH. Their activities and many years of experience in the field of geoinformatics (VirtualcitySYSTEMS) and numerical simulation of physical behavior (CADFEM) complement the development of the “digital twin” of cities, urban districts and buildings.
The “digital twin” based on CityGML (existing buildings) and BIM (new buildings) makes it possible to plan new projects, monitor the entire construction process and investigate what-if scenarios.

The Forum addresses to national and international customers and interested parties from public institutions and industry. Of course, interested parties from municipalities and planning offices are also invited. Developer and users meet here to exchange experiences.

To encourage the discussion of current topics, impulse lectures will be held. After that there will be a lot of time for questions and discussions.

Definition

BIM
“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. BIM software also defines objects parametrically; that is, the objects are defined as parameters and relations to other objects, so that if a related object is amended, dependent ones will automatically also change. Each model element can carry attributes for selecting and ordering them automatically, providing cost estimates as well as material tracking and ordering.”

CityGML
“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.”
