To improve this situation, we must first assess the 
  
economical significance of surveying and mapping in the 
  
national economy. 
nia vorld~vide basis, we spend presntly approximately 
Us $1,350,000, 000 per year for the cartographic exploration 
ors | Ene 
1) Approximatély 1/1000 of the national revenue, or 
2) Approximately + of one per cent of the public 
expenditures, or 
.3) Approximately U.S. $10 per km“, or 
4) Approximately half & dollar (U.S.) per capita 
The purely photogrammetric expenditures might be 
888essed as being about one third of the above data or 
roughly half a billion U.S. dollars per year. 
It is obvious that the present arrear in control 
coverage as well as in map coverage, particularly in medium and 
large scales, can only be overcome by increased efforts in 
terms of esgentially increased photogrammetric surveying and 
  
mapping budgets and in terms of an increased photogrammetric 
personnel. In planning phoiogrammetric education in various 
countries, the aspect must be thken into account.
