and less. The accomplished maps were used for various purposes, 
such as: General map compilation for City planning, Hydraulic, 
Hydroelectic, and Highway projects, for Geological and Archeolo- 
gical studies, etc. 
'The Phototopographic Section, after the war: 
'The period of 2nd world war had devastating effect to the Phototopo- 
graphic Section not only because the relative works had stopped for a 
long period, but also because many instruments were destroyed or dis- 
appeared during the foreign occupation of Greece. 'Though the Section 
had suffered in such a way, it contributed to the appropriate amount 
of effort for the rebuilding of the ruins of the country during the 
war. So, in 1946 pictures of 1000 aproximately villages destroyed 
were taken, and the compilation of maps in a scale of 1:1000 or 1: 
9 000 was started. At the same time many special photographs were 
taken in a scale of 1:5 ooo, mainly, for hydraulic or in a scale 1:20 
ooo for forestry studies. Since 1950 with the assistance of Marshal 
plan, the supply of photogrammetric instruments and apparatuses 
started, and in the meanwhile, many government orders were given 
for the execution of really extensive works in a scale of 1:20 000 
and 1 : 5000 for the studies of different projects, particularly, terri- 
torial improvements, hydraulic, geological, mineral, eletrical plans. 
We should specially mention the compilation or aerophotographic 
maps of many cities of the country in a scale of 1:2000 for studies 
of the electrification projects. In conclusion, during the period un- 
der examination and particularly till 1952, the following instru- 
ments were supplied : 
Photocartograph Nistri (1949) 
Stereographometers Nistri (1949) 
Stereoplanigraphs C7 Zeiss- Aerotopograph (1951) 
Autographs A6 Wild (1951) 
Automatic Wild Rectifier (1951) 
Automatic camera Williamson 9''* 9°", £ 6°” (1951) 
Multiplex Williamson (1952) 
Kelsh plotter (1952) H 
Semiautomatic Rectifiers Zeiss- Aerotopograph (1951) 
Mirror stereoscops with stereometers (1951) 
While on the other hand, we had the following accomplished works, 
briefly : 32334 of taken pictures in 212 flights; compilations of dif- 
ferent maps, among which, the most important are in a scale of 
1:20 000 covering an area of 18 500 sq. km. approx and in a scale of 
1 : 5000 covering an area of 4500 sq. km. approx.

In addition to the Survey of India, other Departments using Aerial Photography for studies, 
are the Geological Survey of India, Oil & Natural Gas Commission, Damodar Valley and other project 
organizations. 
The activities of these Departments are very limited and are confined to their special 
fields of work. Photogrammetry is taught in a few Universities as part of a wide course in Engineer-
