photogrammetry

[PEin2010]

unless otherwise specified, is it to be assumed that the photo size is 9 inch by 9 inch?

reference problem #109 - 120 solved surveying problems

In problem #109, they don't specify the 9 inch width but it has been used in the solution.

Thank you

In Survey Principles, pg 90, it states that the negative commonly measures 9in squared.
