Paleolthic Site Distribution Characterization based on GIS Technique in the lower part of Youngsan river basin, Korea

This research is aimed at revealing the distribution pattern of paleolithic archeological sites with an aid of GIS in the lower part of Youngsan river basin and its distributary sub-basin along Sampo river. Such geomorphological parameters as absolute elevation, slope angle, orientation or direction of site, vertical distance from drainage, horizontal distance from drainage were obtained from DEM data. In addition local pedology, vegetation and geology of the sites were taken into consideration in order to relate them with the OEM data. Descriptive statistical analysis was carried out to connect relationship among different parameters. As result the vertical distance from the local drainage, the horizontal distance from the local drainage (or absolute elevation), slope angle and site orientation are main parameters to designate paleolithic sites of the area. It is particularly interesting to note that slope angle is controlled by geology, i.e., gentle slope is converged into granite terrain, while relatively-sleep slope related to granite gneiss areas. Lastly an absolute elevation is reversely proportional to the horizontal distance from the local drainage.
