ABSTRACT. This paper is an attempt to compare selected software options for processing of LiDAR data. It is focused on filtration and classification of the ground points for the purpose of archaeological sites identification. We confronted popular commercial Terrasolid software with LAStools released under the LGPL license. To accomplish this task we used data gathered in the frame of ISOK project (Computerized Information System of Country Protection from Extraordinary Hazards), implemented in Poland several years ago. In order to examine the effectiveness of the software algorithms we selected well-known archeological sites of various landforms (barrows, megaliths, hill forts) to perform the test. Obtained results were compared with the classification provided within the source data of the ISOK project. It allowed us to indicate the advantages and disadvantages of each tested solutions.

Upowszechnienie się w ostatnich latach lotniczego skaningu laserowego (ang. ALS -Airborne Laser Scanning) stworzyło dla archeologii nowe źródło informacji o olbrzymim potencjale.
