Abstract 

The article presents a research of the accuracy of the digital terrain model (DTM) based on measurements photogrammetric and air laser scanning (ALS) in the Lysica massif in the Świetokrzyskie Mountains. The high accuracy of DTM of ALS measurements, meeting the requirements of ISOK specification, has been confirmed. Significant errors were found on the topographic map, which was the material for inventory of forest habitats. In extreme cases, altitude errors of the spot heights exceeded 5 m, i.e. the Skala Agaty top, whose actual height is 613.9 m a.s.l., was shown on the topographic map as only 608,4 m a.s.l.
