h) The Geographical Survey Office usually executes all work 
on maps 1:10 000 (that 1s geodetic and photogrammdtric work) but 
on maps on larger scales only the photogrammetric work. Practically 
all air-photographs for mapping are taken by the Geographical Survey 
Office. 
The Land Survey District Organization executes all work with the 
exception of air-photographing and photographic work.
