Hello,
I am a civil designer with limited survey experience,Ā trying to understand more fully the concepts behind coordinate systems and transformations.
In my reading and review of the subject, I read the terms "On the Grid"Ā often.Ā Ā Also, I see the term in reference to Grid Based Transformations.Ā I have to assume this refers to the grid on the ellipsoid; latitude and longitude lines.Ā But, I believe it could also refer to the grid of a projected datum ?
