In addition Photo Identification was to be obtained of all marked survey control. Panelling was the process of accurately laying out large sheets of white plastic to form a cross over the Survey Control Points (Points where the position is accurately known) so that they could then be photographed from the air. The positions of these crosses could then be accurately transferred from this new photography in stereo onto the aerial photography coverage used to produce mapping.
