StarNet v6 manual - Engineering Surveyor

Chapter 1 OVERVIEW
The STAR*NET software suite handles general purpose, rigorous least squares analysis
and adjustmnents of 2D, 3D and 1D land survey networks.
Four STAR*NET editions are available to fit the particular needs of the user:
� Standard Edition – Handles 2D/3D survey networks. Differential leveling data may
also be combined in a 3D adjustment. This edition includes all the base features that
make STAR*NET so useful to surveyors. Some of these base features include an
instrument library facility, points reformatter tool, DXF transfer tool, grid-to-ground
coordinates converter, network graphics display with zoom, pan, find and inverse
capabilities, point and connection inquiry from the graphics display, and much more.
� PLUS Edition – Adds a separate 1D differential leveling network adjustment facility
to all base features of the Standard Edition.
� PRO Edition – This high-end edition adds GPS handling and geoid/deflection
modeling capabilities to all features of the PLUS Edition. It includes a vector
importer that supports most popular baseline formats. Special GPS options allow
scaling of vector weighs and application of centering errors separately in horizontal
and vertical directions. Combining conventional, leveling and GPS is made easy!
� LEV Edition – This subset edition handles differential leveling network adjustments,
a perfect low-cost solution for consultants requiring this this type of adjustment only.
One of the main features of STAR*NET is the capacity to weight all input data both
independently or by category. This means that accurately known measurements can be
given more weight in the adjustment than those measurements known to be less accurate.
Completely unknown quantities, such as the coordinates of a new station, may be given a
special code indicating that they are “FREE” in the adjustment. The user can “FIX” other
data with a code so that they receive no correction. In addition, the user can apply
standard deviations to components of any station coordinate so that it will act as an
observation and affect the results of an adjustment. The ability to control the weighting
of data provides the user with a powerful adjustment tool.
The user may select a number of options to determine the type of adjustment to be
performed. All option selections and program commands are made through a dialog
interface, making program operation simple, even for casual users. Every attempt has
been made to simplify the input of data, and the analysis of the results. The program
performs gross error checking, and warns the user if input data appear incorrect.
