The customer also wanted oblique photographs (pic. 3) and for us to measure the volume of an excavated area of the crag, at the northern end (pic. 4).<\/p><p>The area we worked in is located in Kouvola, near Utti Airport, so we needed a flight permit. We were allowed to apply for permission from Utti air traffic control.
