> GIS Based Analysis of Settlement Transformations of the Middle Ages
This poster will focus on two issues. The first one is the use of GIS as a tool for analysing the factors influencing surface artefact survey results. Information about past settlement activities is provided by surface artefact surveys and stored as attribute values of a grid. Geographical factors are derived from a DEM at a 1:10 000 scale by extracting elevation and slope values to other attributes of the same grid. A final group of attributes is formed by information about erosion derived from geo-referenced historical aerial images and land use recorded on 19th century cadastral maps. Factor analysis was then applied to see how these parameters influence the results of surface artefact survey. The results are being tested by comparing four different sites surveyed with the same (analytical) method. Two of these were previously investigated using a different, site search-oriented method so this was taken into consideration. All sites show differences in the most determining factors for artefact survey results – soil type (with related degree of erosion) and the probable intensity of past settlement. The second issue is an attempt to map the influence of hydrological and geomorphological factors on settlement transformation. The input assemblage of sites includes the group mentioned above supplemented with randomly selected sites as well as localities surveyed and published by other scholars. Statistical tools will be applied to test the role of the observed factors.
