! 2D Geodetic adjustment based on an approximate height for each station


! 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)

! Station '1' to be fixed in Lat(north) and Lon(east). 
_LAT_NORTH_FIX; 1
_LON_EAST_FIX;  1


! Indicates the type of adjustment
_ADJUST_2D_LATLON


! 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


! All variances (squared standard deviation) will be multiplied by this value prior to adjustment
_ADJUST_APRIORI_FACTOR; 1.0


! Perform no more than this number of iterations when solving the adjustment. Most networks will
! converge within two to seven iterations when input data contains no major blunders. 
_ADJUST_MAX_ITER; 10


! Consider the adjustment completed, when the current iteration moves station coordinates less than
! this value (from the previous iteration).
_ADJUST_CONVERGE_CRITERIA; 0.001


! Confidence level for reporting - 95%
_ADJUST_CONFIDENCE_LEVEL; 0.95


! Disabled to use OrthoHgt field from each station
!_ADJUST_USE_ELLIPHGT


! Use a known approximate height for each station. This is not a mean height for the network. When
! using this option, you must provide an approximate height value at each station (scaled from a
! map if needed). For projects in highly variable terrain, this method is preferred over the usage
! of a mean project height.
_ADJUST_2D_KNOWN_HGT



! Define the ortho height for each station, since we are adjusting by approximate height at each station
