When the future needs for surveying data and mapping on 
a national level as well as on a world-wide basis have been 
determined, the question arises how many photogrammetrists must 
‘be available in the future, say after 5, 10, 15 and 20 years 
from now. Here we are concerned with planning for future photo- 
gramme try education. Since this item is vital, it is obvious 
that in national and -if existing- in international cartographic e 
committees also, photogrammetry educators must be represented. 
At the first glance at these problems, one is tempted to 
assume that the required number of photogrammetrists in the 
future might have to be increased at the same rate as the popula- 
tion increases. However, a more comprehensive analysis reveals 
that in most countries, progress in photogrammetric surveying 
and mapping operations and the number of photogrammetrists must 
increase at a considerably higher rate and this for two reasons: 
the relatively modest progress made in surveying and mapping e 
operations up to date on one hand and the arrear in assessing 
natural resources and the problem of under-nourishment in large 
portions of the world on the other hand. ; 
The planning for future photogrammetric education 
requires to determine what is the most favorable ratio between 
academic photogrammetrists, photogrammetry technicians and 
plotter operators. Is it 1:2:5 or 1:5:10? Nobody knovs, Some
