GENERAL SUMMARY REPORT OF COMMISSION VII 
PHOTOGRAPHIC INTERPRETATION APPLICA- 
TIONS 
There is much to report in the fields of in- 
terests of Working Groups 3 through 6. How- 
ever little need be said on these subjects in the 
General Summary. Interpretation work in 
the fields of forestry, geology and soils anal- 
ysis still appears to account for the greatest 
quantity of effort; however application in 
urban and industrial fields is being increased 
steadily. Ice interpretation is a rather new 
and interesting field, and one in which more 
work may be expected in the next reporting 
period. 
Of the applications not covered by our pres- 
ent working group structure, the application 
of photographic interpretation to historical 
and archeological research seems to be among 
the most active as recent papers (6) (7) 
testify. It is believed that an archeological 
working group may well be activated for the 
next reporting period. 
CONCLUSION 
The science of photographic interpretation, 
as seen from the vantage point of Commission 
VII, continues to be a restless, rapidly grow- 
ing field. New applications are continually 
being found, and those already existing are 
being pushed into new areas. At the same 
time, there is a growing awareness of the need 
for more research in all phases of the science. 
This need seems, at the moment, to be most 
critical in the area of measuring and improv- 
ing photographic interpretability. 
The need for coordination and communica- 
tion between the many wide-spread and 
widely diversified members of this profession 
remains great. It is believed that Commission 
VII, by further broadening its scope, and per- 
haps increasing the frequency and distribu- 
tion of its reports, can aid considerably in the 
satisfying of this need.
