During the years of 1952—1954 the Land Survey Organization drew 
estate and town planning maps of aggregate area of 61 400 ha. by geo 
detic and photogrammetric methods of which the latter were used for 
some 31 400 ha. or about 50 % of the total area. 
Corresponding statistics are not available in respect of maps for re 
allotments and similar purposes, but the proportion for which photo 
grammetric methods have been used is estimated at about 40 %. 
The Organization of the Photogrammetric Activities. The Land Sur 
vey Organization is explained in Fig. 2. 
The Land Survey Board conducts and controls the plotting activities 
of all its subordinate organizations, and superintends all urban survey 
ing work. 
The chief surveyors conduct and control all surveying work in their 
respective counties. 
The surveyors of the Rural Survey Organizations among others con 
duct the drawing of maps.
