Resolutions 
Commission I has noted that the revised charters of the seven com- 
missions, particularly those of I and VII, will involve them in 
more remote sensing activities of considerable interest, such as: 
all types of remote sensors; a wider range of altitudes, from 
under-water to space; and a greater variety of platforms, from sub- 
mersibles to satellites; physical and environmental factors influ- 
encing remote sensing systems. It is therefore recommended that 
such activities be closely observed, and that appropriate develop- 
ments be reported to the XIII Congress in 1976, with emphasis on 
the comparison of sensor/platform characteristics, operational per- 
formance data, and specific user applieations over the range of al- 
titudes considered. 
Commission I has found that the results of the various Optical 
Transfer Funetions (OTF) are not in sufficient agreement to per- 
mit. the development of an OTF standard. However, because OTF has 
been demonstrated to be a seientifiec tool for evaluating the ima- 
ging quality of lenses, it is recommended that appropriate studies, 
investigations and correlation testing of OTF continue. 
Furthermore, in accordance with the findings and suggestions of 
the Working Group on Modulation Transfer Functions (MTF), Commis- 
sion I recommends continuation of this activity, including estab- 
lishment of specifications and tolerances for test equipment, and 
quality assessment of imagery. 
Commission I recommends the formation of a Working Group on Image 
Geometry, with consideration for relevant liaison with the other 
commissions, particularly III, V and II. It is recommended, as a 
continuation of past efforts to calibrate individual components of 
the system, that one of the tasks of this working group be oriented 
toward the evaluation of calibration procedures for entire photo- 
grammetric-data-acquisition systems. Another task to be considered 
would be metric experiments with side-looking radar. 
In view of the rapid developments in airborne systems which deter- 
mine position, altitude and attitude parameters of imagery, Com- 
mission I encourages studies of the systems approach to data ac- 
quisition to optimize the potential benefit to be derived from the 
integrated use of data from these airborne systems.
