I have a question relating to converting XYZ values from one projection system to another.
If I have a grid of XYZ points in one projection system where
X = Easting
Y = Northing
Z = Elevation
and I convert them to another projection system, should my Z values change as well as my X and Y values or should they stay the same? It seems to me that the Z values should stay the same but I could be wrong.
