This workshop is developed in conjunction with ISPRS WGs III/4 and II/2. Many researchers have studied automated 3D reconstruction of objects and several workshops have been organized on this topic already. This workshop therefore has the multiple aims:
to specify the minimum 3D modeling requirements of NMAs;
to identify, together with industry and researches, the most efficient 3D object capture methodologies for very large areas (e.g. national coverage);
recognizing that “as automated as possible” might not always be the most efficient solution (i.e. guaranteeing a valid 3D object output for 60% of the objects could be preferable over a solution that targets a higher percentage but requires higher levels of human verification);
to examine in addition to the reconstruction processes, the issues of validation of generated objects;
to examine the ability to remain consistent with the original source;
to focus on the most prominent features in (the majority of) 3D topological models, buildings and transportation networks (including tunnels and bridges);
to focus on 3D object generation including the generation of accuracy information on the generated data. Data capture methodologies that can be varied in their sources (e.g. LiDAR, aerial photogrammetry, terrestrial laser scanning, existing 2D data) are of interest but not the prime focus of the workshop;
to explicitly address the distinction between initial data capture and the incremental update of existing national models, which will require embedding the 3D modeling within established processes of continuous incremental updating of countrywide data sets.
To participate in this workshop, you are invited to give a presentation or demonstration on one of the above-mentioned topics. 300-500 words abstract can be sent to j.e.stoter [at] tudelft.nl, by 12 noon, 30th of September 2014
The abstracts will be used to organize the programme. Improved versions or full papers will not be requested.
The OGC CityGML SWG, the SIG 3D, and Hochschule fuer Technik Stuttgart will host a joint workshop to gather requirements, ideas, suggestions, and positive as well as negative experience from CityGML users, data producers, software vendors, and scientists developing and using a CityGML Energy Application Domain Extension. Aim of the workshop is to discuss and define a harmonized version of a CityGML EnergyADE and other development tools like libraries for wide spread use in the development of applications in the energy sector. The workshop will take place on the 27th of May, 2014 in Stuttgart, Germany. Further information on the venue can be found here: Venue.
In the recent years many research groups, companies, and users intensively worked with CityGML on energy topics. In order to promote the use of CityGML in the energy sector e.g. for individual, quarter wide or city wide computations and simulations a coordinated and harmonized version of a EnergyADE is desirable. Participants are invited to communicate their experience in short presentations and to introduce their concepts or modifications or share their experience gained from practical application of CityGML in the energy sector.
