Item Description Settings
Geodetic Datum
Geodetic datum is a reference for geodetic
survey measurements consisting of fixed
latitude, longitude and azimuth values
associated with a defined station of
reference. You must have the correct
geodetic datum selected in your plotter so
that it will reference the correct point on
the chart for a given latitude and longitude.
Although WGS-84 is now the world
standard, other categories of charts still
exist. Refer to Appendix for a full list of
geodetic datum.
See Appendix for full list.
