GRD: Datum to Grid Transformation (Map Projection)
$PASHS,GRD,s1
This command enables or disables the usage of the user-defined datum to grid
transformation to position outputs, where s1 is either NON (transformation disabled)
or UDG (enable user-defined datum to grid transformation). The GRD command is
used in conjunction with the $PASHS,UDG command, which is used to select the
desired datum to grid transformation parameters.
Example
Enter the following command to enable the user-defined datum to grid
transformation:
$PASHS,GRD,UDG
