1. Introduction. 
Since several years, many attempts for analyti- 
cal aerial triangulation, especially in the field of 
theory, have been developed and published. But 
it seems that the method has not yet been brought 
  
A medium scale electronic computer such as 
IBM 650 is very convenient for this method. 
The computer which we have been using, is named 
NEAC 2203—all tranzister type computer made in 
Japan. The average time spent for computation 
per model must be less than 4 minute theoreti- 
cally, including all the computation procedures 
necessary to obtain the finally typed out results, 
starting from raw material. But important prob- 
lem lies in the programming for filtering non-
