Smart District Data Infrastructure (SDDI)
More than 50% of the world population is living in cities today and the number is further increasing. No matter if looking at environmental noise, air quality and particulate matter, energy usage and production, or traffic flows - in order to achieve or maintain a high quality of living in cities, municipalities and companies must take into account many different concerns simultaneously. The concept "Smart District Data Infrastructure" (SDDI) provides planners with the necessary set of flexible tools. Entire cities or just city districts are represented by 3D virtual city models which are linked with dynamic data, for example, on the traffic density or energy consumption. These models are used for monitoring and evaluation of the current situation, and especially for simulations of future developments and an early impact analysis.
As one of 100 winners from about 1000 candidates the project has been awarded "Landmarks in the Land of Ideas" 2016. The goal of the "Germany – Land of Ideas" initiative and Deutsche Bank is to make innovations visible in Germany and abroad and to strengthen the economic potential and sustainability of Germany as a location. This year, in 2016, the competition "CommUnityInnovation – a model for success" is awarding projects that show the added value and potential of joint action, whether in business partnering, scientific networks, or neighbourhood initiatives.

Future Cities Pilot Phase 1
The "Future Cities Pilot" (FCP), an initiative by Open Geospatial Consortium (OGC), aims at demonstrating and enhancing the ability of spatial data infrastructures to support quality of life, civic initiatives and urban resilience. The first phase of this pilot project (termed FCP1) is based in Europe and is sponsored by Ordnance Survey Great Britain, Institut National de l'Information Géographique et Forestière (IGN) France, city of Sant Cugat del Vallès (Barcelona), Spain and virtualcitySYSTEMS GmbH Berlin and in collaboration with buildingSMART International (bSI). The objective of the OGC pilot project is to demonstrate how use of, international standards such as CityGML and IFC together can provide stakeholders with information, knowledge and insight which enhances financial, environmental, and social outcomes for citizens living in cities. Results from this initiative will be documented in Engineering Reports (ERs) in the context of a hands-on engineering experience. This initiative is aimed to develop, test, identify gaps and demonstrate the use of these technologies in a real world-type scenario developed in collaboration with the sponsors. The final demonstrations will be presented in Smart City Expo in Barcelona in November, 2016. [more...]
3D City Database
The award winning 3D City Database (3DCityDB) is a free 3D geo database to store, represent, and manage virtual 3D city models on top of a standard spatial relational database. The database model contains semantically rich, hierarchically structured, multi-scale urban objects facilitating complex GIS modeling and analysis tasks, far beyond visualization. The 3D City Database comes with additional software providing easy data exchange or facilitating coupling with cloud services. The 3D City Database content can be directly exported in KML, COLLADA, and glTF formats for the visualisation in a broad range of applications like Cesium WebGL, Google Earth, ArcGIS and ArcGIS Explorer.

3D City Model of New York City
In this student project a semantic 3D city model of New York City (NYC) has been created based on datasets provided in the NYC Open Data Portal. Different 3D feature types were derived from existing public 2D and 2.5D datasets using spatial and semantic transformations together with (some) photogrammetric analyses. The realized process integrates 26 different datasets from five departments of the NYC administration. The resulting 3D city model is represented in a homogenized and integrated way using the international standard CityGML of the Open Geospatial Consortium (OGC). It comprises all NYC buildings, land parcels, roads, parks, the digital terrain model, and water bodies – all with 3D geometries. We provide the resulting CityGML datasets for download as Open Data as well as a 3D web-based visualization of the entire city model on the project web page. [mehr...]
The DFG research group "Computer-aided cooperative planning in multi-scale 3D city and building models" aims at researching and developing methods and techniques for cooperative planning of infrastructure. The project involves five groups at the Technical University of Munich and the Karlsruhe Institute of Technology.
The sub-project "advanced geo-web services for the requirements of multi-scale 3D-route planning" belongs to the Chair of Geoinformatics. [more...]
CityGML is an international standard of the OGC which specifies an application independent Geospatial Information Model for semantic 3D city and landscape models. Version 2.0.0 of the standard was adopted by the OGC in March 2012. The Chair of Geoinformatics is actively involved in the development of the next major version of CityGML. The overall work scope for CityGML 3.0 will include changes to CityGML’s level-of-detail concept, additional semantic model structures such as building storeys, floor plans and utility networks, as well as new complex attributes such as time series and metadata.

Geodata Pool Lake Constance
The mapping and cadastre authorities of Baden-Wuerttemberg, Bavaria, Austria and Switzerland launched a pilot project which aims at prototypically transforming the topographical data together with the cadastre data to the INSPIRE data models from Annex I of the INSPIRE Directive using semantic transformation and to provide them via view and download services. The semantic transformation is executed by means of two different approaches, the format-driven approach as well as the model-driven approach. [more...]
Model-driven approach for accessing distributed spatial data using Web Services – demonstrated for cross-border GIS applications (mdWFS)
The project aims at developing an approach for web-based schema transformation of geospatial data. It includes the specification of a conceptual language for defining schema mapping rules for semantic transformation as well as the specification of an interface for a model-driven web service able to carry out semantic transformation.

Prototypische Enwticklung Mobiler Anwendungen im Kontext von INSPIRE und COPERNICUS (InGeoSat 2)
Ziel dieses Projekts ist die Entwicklung einer prototypischen Anwendung auf Basis einer mobilen GIS-Plattform. Unter dem Android Betriebssystem wird eine native Android-Applikation implementiert, mit welcher primär INSPIRE, COPERNICUS und InVeKoS-Daten visualisiert werden. Zudem besteht die Möglichkeit über standardisierte OGC- und INSPIRE-Webdienste externe Geodaten einzuladen. Die Potentiale der mobilen Plattform werden anhand einfacher Funktionalitäten der Applikation aus den Bereichen Flurbereinigung, Kataster und Landnutzung sowie der Kombination von INSPIRE- Datenstrukturen mit Fernerkundungsdaten (COPERNICUS) und Landnutzungsdaten (InVeKoS) aufgezeigt.

Modeling City Systems - A Platform-based Approach for Climate-aware Integrated City Plannig and Management
In addressing the challenges to meet the 2050 Greenhouse Gas reduction targets for Europe coupled with the aspirations to improve sustainability and liveability, it is critical that city planners, developers and decision-makers have the capacity to understand how city systems operate, how they interact, and what impact changes to systems has on the system itself and other interacting systems. The growing complexity of city systems and the added complexity of external and growing pressures means that solutions which model, analyse, and help to operationalize systems are more needed than ever before, and inherently require a greater degree of sophistication than ever before. This project builds on the work of the Sustainable City Systems Platform, which has identified urban design, planning and management solutions as one of the biggest opportunity areas for the Climate-KIC and therefore one of three priority areas for 2014.

Indoor Navigation with different Locomotion Types
The purpose of this project is to support different types of locomotion for indoor navigation through determining safe navigable subspaces for each type of locomotion namely flying, walking, and driving using semantically enriched 3D building models. The subspaces are computed using geometrical-based method i.e., configuration space. The whole subspacing procedure is carried out in Multilayered Space-Event Model (MLSEM). MLSEM is a framework which is based on sound mathematical rules and provides application schema i.e., IndoorGML.[mehr..]
