NGS has developed nine interactive, online ADJUST UTILITIES applications for the NGS Toolkit.

(PC versions of this software, and the source code, can be downloaded from the NGS PC Software Download Page).

• BBACCUR2
  provides a formatted listing of the external and internal accuracies which have been computed by ADJUST--sorted in numerical ascending order of external accuracy. Output from ADJUST run with accuracies, is used as input.
   
• CLUSTER
  identifies geodetic stations which are common to two data sets with respect to name or a given position tolerance.
   
• DIFLATLON2
  finds the difference in position and orthometric height for the same station as reported in two horizontal files with *80* and *86* records.
   
• ELEVUP
  creates a bfile which combines the bfile output from the constrained horizontal adjustment with the bfile output from the constrained vertical adjustment. This new bfile contains *80* records with adjusted positions from the horizontal and *86* records with the ellipsoidal height from the horizontal adjustment and geoid heights form the vertical adjustment.
   
• ELLACC
  computes ellipsoidal height order and class for a project. Output from ADJUST, run with accuracies, is used as input.
   
• MAKE86
  adds *86* records to the bfile. If the existing *80* records contain orthometric heights, these are added to the new *86* records.
   
• MODGEE
  In preparation for network and local accuracy computations , MODGEE is no longer necessary. GFILEs of any order no longer need to be scaled.
   
• PREPLT2
  reads ADJUST(v4.30) output file and writes residual components, baseline length, SSNs and designations to an output file in tabular format.
   
• QQRECORD
  adds qq records to the afile (used by ADJUST) to compute accuracies for all observed lines. Either the gfile (for GPS projects) or the bfile (for classical terrestrial projects) can be used as input.
