This series comprises aerial survey photographs of sites at which scientists from Katherine Research Station were carrying out research. The localities covered in the series are Cutta Cutta, Katherine/Four Mile Farm, Manbulloo and Tindal. The photographs are mostly in colour, although for many 'runs' there are both colour and black and white prints of the same frames.

The items are held in batches according to place, date and run number. The batches are arranged in alphabetical order by name of the areas photographed and then loosely in chronological order. Within the chronological sequences the batches are held loosely according to run number and whether colour or black and white.
