Urban System Projects
at the Visualization Center TESSIN VISLab
Here is a selection of our visualisation studies for urban systems:
Energy system infrastructure and storage
An environmental information system for the state of Schleswig Holstein, Germany, has been set up, integrating GIS data on renewable energy sources and infrastructure, topographical models, and subsurface information for an overview of the current state of renewable energy production. Simulation results for a compressed air energy storage in the stratigraphic formations and an aquifer thermal energy storage for a district of the city of Kiel demonstrate options for large scale energy storage in the subsurface. Adding the spatially discritised heat demand completes the overview of the current energy system infrastructure.

Urban Infrastucture and Water Systems
Data and model integration for urban water systems of Chaohu Lake, China and the city of Chaohu itself. Included are a wide range of environmental data as land use, streams, channels, the lake, as well as online monitoring systems. Integrated into the resulting 3D scene are results from numerical simulations of the Lake (via GETM), the groundwater within the lake catchment (via OpenGeoSys) and the sewage system and storm water channels in the city of Chaohu (via SWMM).

Shallow Geothermal Energy Systems
Visualisation for the planning of ground source heat pump systems for heating and cooling supply of a new residential district in the North of Leipzig, Germany. Included are representations of subsurface structures acquired by geophysical exploration in combination with borehole heat exchangers and the simulated groundwater level.

Urban Climate
The influence of the absence or presence of buildings on urban microclimate is simulated and depicted in the actual building plan for a quarter within the city of Leipzig, Germany, including simulated wind directions and their influence on temperatures at different elevations.

Waste Water Treatment
Options for centralised vs decentralised waste water systems for small villages in Jordan, displayed in the 3D geographical context. Integrated are a wide range GIS data sets for various scenarios for fresh water and sewage systems for cost evaluation based on high-resolution digital elevation models.
