Database and geographical information systems
Michael Märker - Zara Kanaeva
The research group deals with questions concerning remote sensing applications and the development of a RAIS (spatial archaeological information system). Therefore, we will analyse the spectral signature to characterize relevant archaeological objects and spatial pattern using ASTER-, LANDSAT- and stereo aerial photographs. Moreover, we will utilize microwave reflectance to classify surface characteristics such as roughness, humidity, dielectricity.
A second focus is the data analysis. Therefore, existing digital physiographic base data, archaeological filed information and palaeo-climatic information will be integrated. Moreover, additive topographic information will derived by terrain analysis These information will be assessed by data mining technologies such as geo-statistics and „machine-based-learning“-methods to derive relevant physiographic entities of potential archaeological field sites (predictive site modelling). Besides the predictive site modelling spatio-temporal point information such as vegetation-, climate-, soil-, hydrographic information will be reconstructed (Postdiction) and illustrated for relevant project intervals (20 000 BP - 3 Mio. BP).
The information strata mentioned above will yield work hypothesis for the simulation of the expansion of early humans. These hypotheses will be tested with static cost, barrier and corridor analysis in order to reconstruct potential expansion paths. Eventually, the expansion dynamics can be simulated using agent based models.
Moreover, the research group “Database and GIS” covers several service functions for the entire project, like providing the database system with WEBGIS functions and the management of hard and software systems.
