AERIAL TRIANGULATION 
The Commission III's General Report

A —- GENERAL OUTLINE 
ANALYSIS OF THE COMMISSION III's TASKS 
a) The preparation of the Commission III's report requires an anticipated and 
serious examination of the aims of the Report itself, as well as the ones of the same 
Commission, whose report is the result. The essential premise of such an enquiry is 
the clear definition of the limited field of interest and activity of Commission III. 
[n recent years, namely since the Scheveningen VI Congress was held in 1948, 
the following title « The aerial triangulation and its applications to Geodesy » has 
been specifically employed by Commission III. Since then, the same Commission 
took part in all the succeeding Congresses under such a title. 
The analysis of the repots drawn-up during the past quadrienniums, the commu- 
nications, discussions and above all, the answers to the questionnaire given out in 
expectation of the IX Congress, persuaded us that such a definition does not befit 
Commission IIT. In fact, while aerial triangulation can substitute only in some very 
rare cases geodetical operations, it is geodesy itself, however, that in most cases helps 
and sustains aerial triangulation with any method it is carried out. 
Geodetical applications of Aerial Triangulation, supposing they exist, are so ne- 
gligible in comparison with all other applications, that the definition contained by 
the title, not only does not mean once, but on the contrary, it could give one the feeling 
of a limited possibility in the application of Aerial Triangulation. 
Owing to the doubt arising in the interpretation of the limits of Commission 
III's interest, we must try to avoid it by reducing the Commission's purposes within
