I am sorry to be a nit-picker but not "NAD 83" nor any other NAD is a
North American Datum establishes how the geographic coordinates
are referenced and its only connection to a projection are the
defines in performing a projection. Note that projections is plural as
projections can be applied to geographic data of any one datum.
For the area of typical NAD application there are three projections that
are normally applied: Transverse Mercator, Lambert Conformal Conic and
I will now return to my cave.
