Abstract

The development of surveying methods and equipment has moved from conventional surveying methods to modern technologies such as Unmanned Aerial Vehicle (UAV) aerial photogrammetry or Terrestrial Laser Scanning (TLS). Our research deals with the comparison of spatial data obtained by these methods in the surface quarry Dreveník, Slovakia. Point clouds obtained by both methods were compared using CloudCompare and Leica Cyclone 3DR software. The mean absolute distance of the point clouds was 2.02 cm and the standard deviation between point clouds was 2.48 cm. Our results confirmed the compatibility and the possibility of combining point clouds.
