Abstract. In this paper, the experimental research utilized UAV imageries of two areas, assessed the accuracy of aerial triangulation on the basis of different photo-control points distributions using two kinds of software (Geolord-AT and PixelGrid). The experimental results show that the accuracy of aerotriangulation of UAV imagery can be satifactory to the accuracy of 1:500 scale topographic maps in the intensive control conditions. The experimental processing steps and results provide experience and reference for production.
