use: Some infrared experiments have been 
carried out; horizon pictures are being used 
to get rectification data (RMKH 21/18). 
AUXILIARY DATA UTILIZED StatOSCOpe: 
Readings are recorded at flying altitude of 
4,500 m.; horizon camera RMKH 21/18 is 
being used. 
New Instruments

purpose: Compiling of topographic maps; 
to be used with aerial photography of alti 
tudes 500-9,000 m.; making of contact prints 
on paper or glass; plotting of maps 1:500- 
1:5,000 and cross sectioning.

Activities 
IGN, a public organization attached to the 
Ministry of Public Works and Transporta 
tion, succeeded to the Geographical Depart 
ment of the Army 1940. Its task among others 
to chart the French Territories (Metropolitan 
France and overseas departments and terri 
tories). Within the framework of cooperation, 
it also makes base charts of the independent 
states of Dark Africa that once belonged to 
the French Community. All base charts are 
now made by aerial photogrammetry. 
GSPT was organized in 1933 to carry out 
aerial stereophotogrammetric and terrestrial 
mapping at scales of 1:500 to 1:10,000 with 
approximately 80 personnel. Equipment in 
cludes the Wild A7 (with EK 5), Wild A8, 
Poivilliers “BP” and Wild A2 (for terrestrial 
use). Products include profiles, geologic silt 
measurements and numerical photogram 
metry studies. 
FSTPW was organized in 1960 with about 
45 personnel to carry out photogrammetric 
mapping at 1:1,000 to 1:50,000 scales and 
aerial photography activities. Equipment con-
