on horizontal, vertical angle, and/or GPS observations.
Data checking programs are included.
CALIBRAT(Version 1.0) - This program is used to determine the scale and
constant corrections for electronic distance

previously determined base lines. The formulas used
in the program are found in NOAA Technical Memorandum
NOS NGS-10, "Use of Calibration Base
Lines."
CARIB97 (Version 3.1) - Specially designed software to compute geoid heights
for the Caribbean Sea. Boundaries of area are defined as
latitude 9-28N and longitude 86-58W. Suggest you read
details before
obtaining software.
COMPGB (Version 1.5) - Tests the consistency and compatibility of the
Blue Book B file (GPS project and station occupation
data) and G file (GPS vector data transfer file).
COMPVECS (Version 1.2) - Program COMPVECS finds differences among redundant vectors in
a G-file. It needs a horzizontal bluebook with *80* position data.
CORPSCON (Version 6.x) - Version 6.x, is a MS-Windows-based program which allows the user
to convert coordinates between Geographic, State Plane
and Universal Transverse Mercator (UTM) systems

and High Accuracy Reference Networks (HARNs).
CR8BB (Version 6.1, Win95/98/NT) - Reformats GPS project information to fit the
requirements of the National Geodetic Survey data
base. The file created, which is called the B-file,
contains project information, station information,
and survey measurements. The CR8BB software functions
independently of the type of GPS receivers used in a
project.
Version 5.4 implements changes reflected in the
July, 2000, updates to the
Blue Book.
These changes include the use of *72* rather than
*71* records and the use of
Annex M
rather than Annex J.
Version 5.5 provides additional sorting capabilities,
renumbering functions, default values, and
makes minor corrections to the handling
of imported SERFILs.
Version 5.5.2 provides additional corrections.
Version 6.1 Further extends sorting, renumbering
and SERFILs and makes field checking less overbearing.
Also, sized better for 800x600 resolution and provides
for the new ARP columns in the *27* record.
This version supersedes all previous versions.

temperature differences, refaction corrections, rod corrections
and plotting. Also included are routines for
editing *.lvl files and VERTOBS files.

as well as aid the casual GPS user.
The USNG provides an easy to use geoaddress system for
identifying and determining locations with the help of a USNG
gridded map and/or a USNG enabled GPS system.
