Aerial Photograbhy

- ERIAL photography and reconnaissance
was the newest military weapon in
- troduced in the World War, and by
far the most important. All troop, artillery
and gas movements were planned and di-
rected with the aid of the flying corps.
Aerial eyes spying -perpetually above
the lines removed the element of surprise
attack. There was hardly an offensive by
either side that had not been watched every
day IN ths course of it's preparation by the
opposing side.
Now that war is over, new and interest
ing uses are being developed for aerial pho
Biography and reconnaissance. Some of the
most interesting pictures recently published
in the rotogravure section were taken in the
air. They gave entirely new and striking
conceptions of what certain places look like;
as, for example, the East Lake Country Club,
with it's shining silver lake, it's gabled club
house, it's rolling golf course, it's hard-baked
tennis courts-the whole spread out in
single panorama. Architects, taking their
cue from aerial views, are developing with re-
markable skill the art of making designs
which show how the proposed building will
appear when seen from above. Such a per-
spective is far more graphic than an ordinary
'flat" picture showing one or two sides of
building.

a mosaic air-map OIL New York City. The
airplane flies back and forth above the city,
from one end to the other in predetermined
air-lines, maintaining a level keel and uni
form elevation.
On the bottom side of the fuselage is a
special camera designed for this work. 1t
operates by motor. 1t makes an exposure at
regular intervals, each exposure slightly
overlapping the other. The whole array
of pictures are peced together in their prop
er place. forming an exact mosaic picture.
These are the sort of maps that were made
by army flyers over tie battle lines in France
The military mosaic maps revealed every de-
tail of the enemy's forces, troop dispositions,
entertainments, artillery locations, lines of
communication, etc. Only by means of
camouflage painting were the strategists able
to conceal themselves in some measure from
the perpetually prying eyes of the aerial
cameras
But the mosaic air-map of New York lis
not to be used for military purpose. Its
value in peace, for construction instead of
destruction, has already been demonstrated
in interesting ways. police inspector
pointed out, when his eyes first alighted
upon the finished map, that he could study it
and locate every roof exit, scuttle hole and
skylight in his district thereby enabling him
to direct his forces with much more precis-
ion in a search of a given area for police
fugitive.
The New York authorities plan to use the
mosaic for many practical purposes, one of
which will be as an aid in projecting the
lines of future development of the city. In
other words, "city planning from the air.
A company owning fifteen hundred square
miles of timber in Canada is negotiating
with an aerial Photographic corporation to
make mosaic map of the whole enormous
tract. Months will be required for the task.
The map will show "burnt-over timber,
blown-down timber, streams, the number of
logs on booms, the number of logs on banks
Of streams, roadways, hills, valley, and all
other details of the terrain
Another interesting use of the aerial
camera e in making geological surveys of
large area inaccessible by other means Of
approach Scientists predi:t that vast stores
Of mineral wealth are destined to be found
in this manner.
