Keywords: Digital Photogrammetry, UAV, Accuracy Investigation, Mapping Techniques Abstract. The Low-cost Unmanned Aerial Vehicle (UAV) has been used as a platform for photogrammetric data acquisition. Two techniques were accepted for mapping. One is remotely-piloted aircraft with mounted digital camera Sony NEX–5 for low altitude photogrammetry. The flying height was about 30 m. Another is close range photogrammetry taking images from building – geometric situation similar to aerial case (vertical images). The Trimble R6 GPS has been used for determination of ground control points coordinates exploited in exterior orientation procedures. DTM’s creation via image matching and area mapping was performed by software LISA designed at University of Düsseldorf. Comparison analysis of applied two techniques efficiency and application possibilities has been carried out. The accuracy assessment is given. The residuals in x and y at every point and standard deviation in exterior orientation procedure of images from UAV platform is about half of pixel size referring to the image, i.e. 0.14 mm. Experimental accuracy investigation regarding UAV and GPS data shows that maximum absolute planimetric displacement is 0.25–0.30 m. Such data fulfils the accuracy requirements for large-scale urban area mapping.
