In this paper approaches of historical, archaeological object detection from airborne laser scanning (hereinafter referred to as ASL) data were shown. Presented approach of automatic extraction of potential charcoal pile was the analysis of a selected processing of digital terrain model. In this example, it was attempted to detect archaeological sites on a small test area by usage of template matching. Positive results have proved a great number of detected objects. Methodology applied in the research allowed for finding of a large percentage of measured objects indirectly. Presented approach was also assessed by the results of object extraction in respect to field measurements in the area of interest, as well as effectiveness of automation procedure.
