AERTAL PHOTOGRAPHY
The majority of aerial photography flown in Australia and New Guinea is the
result of demands from various Commonwealth and State Government departments,
To assist in the investigation or development of their own interests, private
enterprise organisations also have photography flown for their use by civil contractors,
even though governmental photography may, with certain restriction, be made available to
them, This work is not usually very extensive.
Commonwealth Photography
From its ineeption until disbandment in 1953, the Photographie Squadron of the
Royal Australian Air Force was the main source of supply of aerial photography, Up to
the beginning of the war, photography was flown in Anson aircraft using standard F8
cameras at a scale of approximately 1:20,000 whilst during the war years DC3 and Hudson
aircraft using Williamson Eagle IV and Fairchild K17 cameras photographed large areas of
Australia and New Guinea, As a war expedient trimetrogon photography was introduced for
mapping, but was soon discontinued when vertical photography became available,
During the post-war years, photography at scales varying from 1: 05,000 t0
1:50,000 has been flown mainly in Mosquito aircraft using the K17 and OSC cameras.
With the disbandment of the Photographic Squadron, private enterprise took over
the task of meeting this requirement, and have been engaged on this work ever since,
Several private companies have contracted for supply of aerial photography since 1953 but
to date only one company is in current operation in Australia,
The Snowy Mountains Hydro-Electricity Authority, which is carrying out work in
connection with hydro-electric power and water conservation, have their own Beaver air-
craft, which besides other duties, carries out aerial surveys of a specialised nature for
its own use,
Recently the Commonwealth acquired three Wild RC9 super-wide angle cameras, Two
neras have been used for photography of a considerable area of the Great Barrier Reef
nd the Officer Basin in West Australia (for the purposes of oil search), whilst the other

requirements in several ways.
Some agencies arrange with a private contractor to supply aerial photographs to
specification whilst others have a full time aerial survey unit vithin their own mapping
organisation, Under the latter circumstances, the usual method of obtaininkc aerial
photography is to charter an aircraft from a private company, who also supply the pilot.
The mapping agencies supply their own camera, cameras operators and navigator,
Private Photography
