This article discuses the precision analysis of the laser scanning of the city of Krakow performed  in 2006.

In the process of the precision analysis of the lidar measurements of Kraków calculations of the mean square errors of the position RMSEX  RMSEY  RMSEXY , mean square error of the height RMSEZ as well as calculation of the percentage of deviation (lidar and photogrametric data were compared for 235 exemplary points) were proposed.
