Projected coordinate systems are based on geographic coordinates, which are in turn referenced to a datum. For example,State Plane coordinate systemscan either reference the NAD83 or NAD27 geodetic datums. NAD27 Datum vs NAD83 Datum TheNAD27 datumwas based on theClarke Ellipsoidof 1866: TheNAD8...
I have scanned maps from the 70's into .jp2s, and am having a hard time converting the coordinates from NAD_1927_StatePlane_Texas_North_Central_FIPS_4202 to NAD_1983_StatePlane_Texas_North_Central_FIPS_4202. The coordinates given on the maps are in NAD27, so I used the Georeferencing ...
