Geographic Information System (GIS) – 3D Visualisation
The doctotal students assemble and integrate diverse historical, archaeological, and environmental facts into a dynamic picture of human development. The heterogeneity of data and observations, all focusing on the same object, yet using different methods, spatial resolutions, or scales, demands a strong unifying database. Geographical Information Systems (GIS) are highly suitable since they provide established sophisticated techniques for the storage, retrieval, and processing of geodata coming from different sources.
Furthermore, GIS offer a wide range of specific tools, including 3D visualisation, for advanced spatial analyses and environmental modelling, making possible the identification and simulation of the complex interactions and feedbacks that underlie the spatial structure of landscapes on multiple spatial and temporal scales. To make the integration of data from different projects possible, a metadata information system will be developed to facilitate queries to a common GIS-database that will merge new data sets from laboratory work, field research, and remote sensing with existing geoscientific meta-data. In addition to more classical GIS systems, a virtual reality CAVE environment will be created. The system will be used to visualise not only the field data and observations, but will also provide the visualisation of non-numerical information.
A new Graduate School GIS laboratory was installed in 2007/08 to support projects dealing with GIS based spatial reconstructions. In addition to the setup and maintenance of the newly created GIS infrastructures, technical assistance and classes/tutorials to the PhD students are provided.
