Early investigations

I.H.Lambert M.V.Lomonosov

"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

Early investigations
