MI02F.RTB is the RTAB official survey coordinate file for Martin County.

Many surveys from R-45 to R-65 has been surveyed using different transact angles than those in MI02F.RTB

In general the surveyors were using a transact normal to the shoreline
which is the preferred angle.  The updated RTAB file matches the actual bearings in
use today.

PLEASE use the MI17F.RTB file and see the comments in the file.  Note that NO monument coordinates were altered.
