APPENDIX A 
PROPOSED RESOLUTION FOR COMMISSION II 
It is proposed that manufacturing and testing laboratories be urged to supply more 
effectively their instrumental distortion and calibration data in a digital form for 
efficient and compatible entry and use in digital data processing programs and 
equipments. To do this, it is recommended that a commission be formed to draw 
suitable specifications as to the most efficient type(s) and form(s) and format(s) that 
the digital data and documents may take (i.e., punch cards, punched tape, magnetic 
tape, etc.). This calibration data should include geometric data such as lens dis 
tortions, camera-platen errors, film and diapositive errors, and other known and 
measured instrumental errors which can affect the accuracy of photogrammetric 
mapping and orthocorrection of photographs. These specifications must be suffi 
ciently broad in scope to encompass the operation of all types of automatic instru 
ments, analytical instruments, classical (analog) instruments, and distortion 
measuring equipments used in Photogrammetric Mapping Systems.
