spite of the trond for &n increased automation in photogrammetric 
mapping and plotting. It has to be warned here that an exagges 
rated belief in automation might be unwholesome for an efficient 
production, if because of thie belief the present day's produc- 
tion is hampered in the hope that fully automized procedures 
will make up for eventual delays in providing pho togramme tric 
surveying data and map compilation. It should also not pe forc 
gotten that in many countries, there is the problem of unemploy- 
ment and for this very reason & reasonable compromise between 
manpower to be employed and automation must be found. This 
should however not be understood as an adversary statement 
against automation which should be used to its full extent -if 
proved to be more efficient- in overcoming the arrears in 
assessing natural resources and in improving the agricultural 
potential, 
CONCLUSIONS AND RECOMMENDATIONS 
The previous discussion reveals that on a world-wide 
basis, there is a marked arrear in the production of photo- 
gremmetric surveying data and maps. This is partially due to 
“ & lack of planning, of coordination of efforts, of funds and of 
personnel. In the future, it will be necessary to establish in 
each country an inventory of the existing ground control, air
