Use a noticeable colour (e.g. red) and draw straight lines along features which will not change ( negligably) between images. For example, draw along field boundaries into, and over, the roads or along runways from the centre of the white cross to the centre of the cross at the other end of the runway. Also draw along road edges at junctions to create crosses where you can select the centre as a tie point. Doing this on each image will allow much better precision of selecting tie points.452 It may be useful (proved so in calibration site of little rissington) to copy the PNGs generated by Attune and draw onto them.
