In this study we explored the positional quality of orthophotos obtained by an
unmanned aerial vehicle (UAV). A multi-rotor UAV was used to obtain images using a
vertically mounted digital camera. The flight was processed taking into account the
photogrammetry workflow: perform the aerial triangulation, generate a digital surface
model, orthorectify individual images and finally obtain a mosaic image or final orthophoto.
The UAV orthophotos were assessed with various spatial quality tests used by national
mapping agencies (NMAs). Results showed that the orthophotos satisfactorily passed the
spatial quality tests and are therefore a useful tool for NMAs in their production flowchart.
