Using Geografic Information System (Gis) Tools to Determine the Settlement Preferences in the Upper Wisłoka Valley and to Demarcate Potential Archeological Sites on the Example of Early Medieval Sites

The article’s objective is to conduct a diagnosis of early medieval settlement and to determine settlement clusters and preferences. The analysis results enable the preparation of maps depicting potential sites. The basic source for the data used in the analyses consists of information collected since the 1970s within the framework of the nationwide Polish Archaeological Record (PAR) project. The data have been subjected to analyses using Geographic Information System tools, such as QGIS, GRASS GIS or Saga GIS.
