A spatio-temporal data base integrating paleo environmental and archaeological data is presented in this contribution. The data base is developed applying a collaborative prototyping approach based on Semantic Mediawiki (SMW, Krötzsch et al. 2006) and OGC standards based Spatial Data Infrastructure technology.
Time and space are the main integrating factors of the presented data base. The data is spatially integrated by its spatial extent. For GIS datasets this extent is present intrinsically. For data, not given in a GIS data format, or not containing explicit geo coordinates, the spatial integration is facilitated by annotating spatial attributes with predefined regions or sites, which translate to bounding boxes, polygons or point coordinates. The same is implemented for temporal data, where the data can be annotated with predefined periods and events, which translate into time-spans (periods) between a start and an end date, or into simple dates (events).
Developing the data base using a prototyping (Naumann & Jenkins 1982) approach means to develop the data model and the interface from the integrated data, and from demands of the users during internal use and operation of the data base application. SMW proves to be an ideal technology for implementing this approach, because model, data and interface are editable and combined in one application.
Based on some example use cases for integrated paleo environmental and archaeological GIS analysis, it will be shown how geographical and archaeological relations within the data base can be revealed. SMW allows to formulate complex queries and export the result in different formats. The complete process from query formulation, the query result export, the import of the data into a GIS, and an example GIS analysis based on the data will be explained.
