In view of the continuous development of ALS (Airborne Laser Scanning), it has become necessary to develop an effective method of controlling the quality of data obtained with the use of this technology. The author presents three main approaches used in literature for assessing the relative accuracy of the ALS data: the method of comparing DEM models (Digital Terrain Model), the method of comparing points and TIN surfaces (Triangulated Irregular Network) and the method of comparing linear elements. Each of these methods is based on a selection of various types of control objects located in overlapping areas between strips of ALS. In addition, a new approach is presented, based on a comparison of roof ridge lines and elevation grids, developed in Poland in order to assess the relative accuracy of the LiDAR data (Light Detection and Ranging) within the ISOK project (IT System of the Country’s Protection against extreme hazards).

Wobec ciągłego rozwoju lotniczego skaningu laserowego ALS (ang. Airborne Laser Scanning) koniczne stało się opracowanie efektywnej metody kontroli jakości danych pozyskanych w ten sposób. Autor zaprezentował trzy główne spotykane w literaturze podejścia do oszacowania względnej dokładności danych ALS: metodę porównania modeli DEM (ang. Digital Terrain Model), metodę porównania punktów i powierzchni TIN (ang. Triangulated Irregular Network) oraz metodę porównania elementów liniowych. Każda z metod bazuje na wyborze różnego typu obiektów kontrolnych, rozmieszczonych w pasach pokrycia między sąsiadującymi szeregami ALS. Dodatkowo przedstawione zostanie nowe podejście, opierające się na porównaniu kalenic i siatek wysokościowych, opracowane w Polsce w celu oceny wzglę dnej dokładności danych LiDAR (ang. Light Detection and Ranging) w ramach projektu ISOK (informatyczny system osłony kraju przed nadzwyczajnymi zagrożeniami).
