! Define datum
! Datum Name; Semi-Major Axis; 1.0 / Flattening
_DATUM; NAD 83; 6378137.000000; 298.257222101


! Define the Units used in this file
! M - meters, U - US Feet, I - International Feet, C - Chains
! D - DMS, DD - Decimal Degrees, G - Grads (Gons), 
! Note: Lat and Lon must always be in DMS format (e.g., 100-30-40.1234 is entered as 100.30401234)

_LAT_NORTH_FIX;   WHITE MTN
_LON_EAST_FIX;    WHITE MTN
_HGT_FIX;         WHITE MTN




! _ADJUST_ keywords
! Keywords starting with _ADJUST_ are used in the Adjust From File option; they are ignored during Import.

! Indicates the type of adjustment (3D Grid or State Plane)
_ADJUST_3D_GRID


! Define if unknown stations (referenced by observations) should be created at Adjust Time.
! Unknown stations are those not defined in the _STA_COORD record (see below).
_ADJUST_CREATE_MISSING_STATION


! Use ellipsoidal Height from _STA_COORD record
_ADJUST_USE_ELLIPHGT


! Grid Zone (see list of all grid zones on our web site)
_ADJUST_GRID;  ILLINOIS,W,1202,TM
! Another way to define the zone (if you have the parameters) is shown below (use linear units defined above)
