BACKGROUND

The Open Geospatial Consortium (OGC) CityGML model has been successfully used in a number of city models in different parts of the world. Presently there is a new version being developed and the draft specification publicly available on GitHub will be utilized as part of this challenge.

Sponsored by OGC Strategic Member, Ordnance Survey (OS), the CityGML Challenge will encourage the configuration of software tools to visualise CityGML data. CityGML is an open data model and XML-based format for the storage and exchange of virtual 3D city models. The challenge is focused on the UK city of Manchester. OS is supporting Manchester City Council in the delivery of the Triangulum Project - funded by the European Commission (EC) - and has collated a range of data resources relating to the geography of Manchester’s Oxford Road Corridor in the form of a data model in the draft CityGML 3 standard.

Triangulum is focused on replicable smart city solutions and frameworks relating to sustainable energy, mobility, and ICT. A range of low-carbon technologies have been implemented in the Oxford Road Corridor, and OS is sponsoring this challenge in collaboration with both Manchester City Council and OGC to support the incubation of mobility and energy innovations.

THE CHALLENGE

We are encouraging software developers to configure visualisation software tools to support the capabilities of version 3 of CityGML, including dynamic data feeds from a range of sensors. The resulting tools and visualisation environment are to be made openly available for one year for wider non-commercial experimentation and innovation purposes, in particular as part of a Triangulum Innovation Challenge focused on energy and mobility applications.

We expect that this visualisation will operate from a database representation of the City Model that conforms to the CityGML 3 conceptual model, and will not be not dependent on any of the CityGML encodings.

Ordnance Survey and Manchester City Council have supplied the Challenge with a variety of data. We expect the visualisations to use as much of this data as possible. Refer to the webinar recordings for details.

A wealth of data and live API feeds for Manchester’s Oxford Corridor have been brought together for this challenge.

Applicants are encouraged to consider a range of visualisation media and consumption options, including augmented and virtual reality.

THE PRIZE

Applicants to this challenge will be invited to present their visualisation tools at a judging event to take place in Manchester on Thursday 24 October, 2019. The winner will benefit from:

  • A £5,000 cash prize.
  • Showcasing of the tool at subsequent OGC Technical Meetings.
  • Recognition from having their tool used as a key resource for the Triangulum innovation challenge.

 

Update Section – New

We have been notified that one of the orthorectified imagery tiles (number 005_001, part of orthophoto_8 zipped file) was not fully processed. Please accept our apologies.

Corrupted tile has been reprocessed and is now available to download from the same location. 

3D textured mesh tiles for 6 AOIs are now provided, beside OBJ, also in Cesium format.

Manchester Virtual Power Plant data is now provided as a set of two zipped CSV files for Manchester City Council (MCC.zip) and Manchester Metropolitan University (MMU.zip) and not a part of Integrated file geodatabase as indicated within the Requirements for CityGML 3 visualisation tool document.

Manchester pedestrian and vehicle count data is now available to download as a separate file and not part of Manchester-I API. The data provided in zipped MCRV file includes sensors reading for 10 locations along Oxford Road and Oxford Street in Manchester. 

Clarifications regarding the creation of OS CityGML v3.0 LOD2 data for buildings:

Buildings data was automatically generated using Virtual City Systems software, exported in CityGML v2 format and then translated into CityGML v3 using the Java tool developed by the Technical University of Munich (TUM). 

Previous version of the data was defined in incorrect FME namespace. Please accept our apologies. 

The data is now corrected and available for download from the same location on OGC portal

Update for Participant Submissions:
 
The date for submission for the CityGML Challenge has been moved to October 14th.
 
Please let us know how you intend to submit the information and access on your submission.

We suggest you send a link and log in to my email and I can distribute the information to the judges.
 
Also, please confirm you will be attending on October 24 to present your submission. 
 
The amount of time available for each presenter will depend on the number of submissions. Once we have a final count, we will notifiy you on how much time you will have to present your competition entry.
