Request for Presentations on CityGML 3.0 development
The OGC CityGML SWG, the SIG 3D, and Technische Universität München will host a joint
international workshop to gather requirements, ideas, suggestions, and positive
as well as negative experience from CityGML users, data producers, software
vendors, and scientists with CityGML 1.0 and 2.0 in order to guide the
development of the next major version of CityGML. The workshop will take place
on the 20th and 21st of June, 2013 in Munich, Germany.
In recent years many research groups, companies, and
users intensively worked with CityGML and many possible extensions or modifications have been prototyped or proposed.
In order to promote an open discussion this workshop will address a number of
major issues and provide a forum for groups and individuals who can and want to
contribute to future CityGML development. Participants are invited to
communicate their experience in short presentations and to introduce their new
concepts or modifications or share their experience gained from practical
application of CityGML. We explicitly want to point out that no decisions on
presented and discussed items will be taken at this stage of development.
These are the topics to be addressed in the two-day meeting:
THURSDAY, 20 June 2013
• 10:00-10:20 Welcome address from the organizers
• 10:20-12:30 Improved Support for Simulations and other
- Coupling of
CityGML with different types of simulations; time varying feature properties (spatial
and thematic, e.g. energy demand or
production potential for a building along the course of the day / week /
attributes (metadata at individual attribute level like lineage, accuracy, unit of measure,
date of acquisition etc.)
• 13:30-17:00 LOD Concept of CityGML, e.g.
- semantic and
- definition of
separate indoor LODs; floorplans
- more / less /
continuous LOD levels
On Thursday evening a social event will take place giving
the participants the chance to enjoy Bavarian hospitality, food and beer at one
of the famous Bavarian beer gardens or beer cellars (depending on the weather).
FRIDAY, 21 June 2013
• 09:00-10:30 Extension of CityGML by new Objects, e.g.
- Support for
other types of constructions like walls, fences etc.
- Utility networks
• 11:00-15:00 Stronger Harmonisation with 2D Cadastre and
- Admissibility of
2D geometries, definition of LOD0
If you are a CityGML user, data producer, software vendor or
a scientist working with or on CityGML, you are encouraged to participate in the workshop. The organizers
will contact a number of individuals and groups from which they know about their CityGML activities and ask them for presentations
soon. However, if you would like to contribute a presentation, please send a short abstract (300 words) to the organizing
committee consisting of the CityGML SWG chairs and the CityGML editors (please direct submissions to: kutzner [at] tum.de ).
The decision on the acceptance is based on the expected
contribution to the issues named above. Due to the limited time, probably not
all proposals might be considered. In case of too many
submissions, another workshop will be planned. The accepted presentations
will be listed on a frequently updated Wiki: http://en.wiki.modeling.sig3d.de/index.php/Workshop_Munich_2013
The event is sponsored by industry partners and the Chair of
Geoinformatics at Technische Universit‰t M¸nchen. Hence, participation is free
of charge including coffee breaks. Costs for travel and accomodation as well as
the social event on Thursday will be at the participants own expense.
