OBSCHK [version 3.8 - 2008/05/15] Checks the integrity of the B-file (Horiz bluebook) and G-file.   Obschk is not a complete checking program.  Program chkobs performs additional syntax and structure checks on the B-file and should be run prior to obschk.

DOWNLOADS:
obschk.exe is the PC executable.
obschk.txt is the ASCII text documentation file.
samples.zip has sample data files, common to adjust, chkobs, obschk, obsdes
obschk_v38.zip contains program source code.

OBSDES [version 2.5 - ] OBSDES compares a horizontal Blue Book Description data set with its respective Blue Book Observation data set. OBSDES produces a list of error messages along with the description data set record and observation data set information.

DOWNLOADS:
obsdes.exe is the PC executable.
obsdes.txt is the ASCII text documentation file.
samples.zip has sample data files, common to adjust, chkobs, obschk, obsdes

BBACCUR2 [version 1.6 - 2003/08/05] which provides a formatted listing of the external and internal accuracies which have been computed by program ADJUST-- sorted in numerical ascending order of external accuracy. Output from program ADJUST, run with accuracies, is used as input.

DOWNLOADS:
bbaccur2.exe is the PC executable.
bbaccur2.txt is the ASCII text documentation.
bbaccur2_v16.zip contains program source code.

CLUSTER used to identify geodetic stations which are common to two data sets with respect to name or a given position tolerance.

DOWNLOADS:
cluster.exe is the PC executable.
cluster.txt is the ASCII text documentation.

COMPVECS [version 1.2 - 2006/02/16] is used to find differences among redundant vectors in a G-file. It requires a horizontal bluebook with *80* position data records.

DOWNLOADS:
compVecs.exe is the PC executable.
compVecs.txt is the ASCII text documentation.
compVecs_v12.zip contains program source.

page divider image

DIFLATLON2 [version 1.6 - 2005/06/16] finds the difference in position and orthometric height for the same station as reported in two horizontal files with *80* and *86* records.

DOWNLOADS:
diflatlon2.exe is the PC executable.
diflatlon2.txt is the ASCII text documentation.
dll2_v16.zip contains program source.

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 heights from the horizontal adjustment and the orthometric heights and geoid heights from the vertical adjustment.

DOWNLOAD:
elevup.exe is the PC executable.

ELLACC [version 2.7 - 2003/08/05] which computes ellipsoidal height order and class for a project. Output from program ADJUST, run with accuracies, is used as input.

DOWNLOADS:
ellacc.exe is the PC executable.
ellacc.txt is the ASCII text documentation.
ellacc_v27.zip contains program source.

MAKE86 which adds *86* records to the bfile. If the existing *80* records contain orthometric heights, these are added to the new *86* records.

DOWNLOAD:
make86.exe is the PC executable.

MODGEE
2007Aug01 - In preparation for the computation of network and local accuracies, MODGEE will no longer be necessary.   Rather, the variance factor must be computed by placing VVHU at the end of the AFILE when running the final free adjustment.

PREPLT2 [version 1.1 - 2003/08/01] reads ADJUST (v4.30) output file and writes residual components, baseline length, SSNs and designations to an output file in tabular format.

DOWNLOADS:
preplt2.exe is the PC executable.
preplt2_11.zip contains program source.

QQRECORD [version 1.9 - 2005/07/18] adds qq records to the Afile (used by program 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.

DOWNLOADS:
qqrecord.exe is the PC executable.
qqrecord_v19.zip contains program source.
