"Perspectiva
Liber"
F.D. Arago A. Laussedat G. Tournachon
“Camera obscūra"
1759 1764 1840 1858 1860
The proposal
to use “Camera
obscūra"
The proposal
to use images to
create
topographic maps
First aerial
survey from a manned
balloon
He performed
photo surveying
from a roof
of the high building
Photogrammetry – (in greece) photos – light,
gramma – recording, metrio – measurement
