MicroSurvey STAR*NET

MicroSurvey STAR*NET is an easy-to-use Windows application that adjusts 2D/3D survey networks using rigorous least-squares techniques. It handles networks containing conventional observations with up to 10,000 adjustable stations.

If you have used STAR*NET before, you will recognize the same powerful network adjustment functionality that has been used by survey professionals for more than two decades. With the new Version 7, you will find better organization of the reports and plot windows, as well as a handful of workflow tools to ensure you can validate and correct your network as efficiently as possible.


A USB Key is required for licensed operation of this product. The USB Key will be shipped to you, but you can download the software and begin using it immediately in trial mode.

Helping you get the
most out of least squares.

MicroSurvey STAR*NET V7 is an easy-to-use Windows application that adjusts 2D/3D survey networks using rigorous least-squares techniques.

STAR*NET handles networks containing conventional observations combined with GPS vectors, from up to 10,000 adjustable stations. Differential leveling observations can also be included within a 3D adjustment.

Whether a survey consists of a single-loop traverse or a complex network of interconnecting traverses, all observations are adjusted simultaneously to produce a single best-fit solution. STAR*NET can reduce observations to NAD27, NAD83, or UTM, with separate grid factors calculated for all distances and t-T corrections calculated for all angles.

It Works

  • STAR*NET is the easiest least squares adjustment package to use and understand.
  • Allows more flexibility in how crews collect measurements.
  • Results have been used by surveyors around the world for more than 20 years.

It Integrates Data Easily

  • Easily mixes conventional total station measurements with GPS vectors and leveling data.
  • Use different instruments on the same job in varying atmospheric conditions and STAR*NET will compensate for the accuracy changes.

Input Files: Simple to Work With & Understand

  • The STAR*NET dat input file can be created by many software packages. Records are one per line and can be edited with any text editor.
  • Input data can be entered in any order. You can simply comment out bad measurements.

Results Are Clear and Reliable

  • STAR*NET results are formatted for quick review. Spot errors quickly and easily.
  • The Sum of Squares, Error Factors, and Chi-Square test are sensitive to the inputs and give excellent feedback reports that offer tremendous flexibility.

Gives You Confidence in Your Work

  • Geo-referencing is easier. Reports output both geodetic and ground coordinates with combined scale factors.
  • STAR*NET produces the least squares ALTA/NSPS results you need for your surveys.

Converters for All Types of Formats

  • Convert raw data from various data collection packages – TDS, Carlson, TSC (Trimble), SMI, etc.
  • Some hardware manufacturers (e.g., Leica Geosystems) offer conversion utilities for STAR*NET .dat format.

Custom Transverse Mercator and Lambert grids may be defined for special local requirements or for grid systems in most areas of the world. Angular measurements are supported in both Deg-Min-Sec and GONS.

STAR*NET comes in several editions: Lev, Standard, Plus, and Pro, along with a number of handy conversion utilities, to ensure you get precisely the tools you need.

Customer Reviews

The simple, user-friendly interface means there is almost no time wastedReview by Dr. Nigel Penna, Newcastle University
STAR*NET has been used at Newcastle University for the teaching of least squares and the analysis of observations since around 1990. I find it an excellent teaching aid, as I use it to demonstrate that the answers students obtain when doing "hand/spreadsheet" computations, using the theory and principles I teach them, are identical to those with STAR*NET if done correctly. This instills confidence in the students' learning and provides a valuable check on their answers. The simple, user-friendly interface means there is almost no time wasted in having to teach students how to use the software, plus it is not memory intensive and has negligible run-time for computations. I find STAR*NET useful since it can be used for the simplest of least-squares problems and computations to illustrate principles and enhance learning, but can also be used for the analysis of larger, practical networks.

Generations of OIT Geomatics graduates have learned to use STAR*NETReview by Jack Walker, PLS, Department of Geomatics, Oregon Institute of Technology
I was considering writing an adjustment program for OIT Geomatics student use when STAR*NET became available in the late 1980's. I was impressed with the software: it was a full-featured, flexible adjustment program without the limitations of other adjustment programs. It is easy to use, and the manual is a good adjustment primer in itself. StarPlus donated the software to OIT for academic use in 1989, and provided updates at no cost, an appreciated level of industry support. Generations of OIT Geomatics graduates have learned to use STAR*NET since that time. (Posted on 4/24/15)
STAR*NET adjustments are taught as standard practice at Renton Technical CollegeReview by Martin Paquette, WA PLS, Renton, Washington
No field control project, whether conducted by total station, GNSS, or both, is considered done unless it is properly weighted and adjusted using STAR*NET. This has been our practice since we first got STAR*NET in the early 1990s, and it has loaded and run flawlessly on every computer we've ever put it on. Students have had the ease of learning the program and running small networks at home using the demo package. (Posted on 4/24/15)
I am pleased to see that STAR*NET will be well supported for many years to comeReview by Ted Eaton, BCLS, CLS, Eaton Land Surveying Ltd.
STAR*NET is an essential tool for anyone combining conventional survey measurements with GPS measurements. It is extremely simple to use and is completely reliable. Its ability to flag inconsistencies in a survey network gives me a great deal of confidence. (Posted on 4/24/15)
I'm sure STAR*NET paid for itself on the first major survey we didReview by Mark Cahill, BCLS, AllTerra Land Surveying & Geomatics
I first started using STAR*NET in about 1993, shortly after completing my Least Squares class at BCIT, where we were taught that least squares adjustments were simply the best way to resolve traverses and control networks. I'm sure STAR*NET paid for itself on the first major survey we did as we rarely had any mis-closure issues from that point forward. We immediately benefited from being able to process traverse data collected in any order and being able to include redundant check shots in the processing.

Now I'm in practice for myself, and I wouldn't process my control any other way. What other program allows you to georeference your survey, compute grid and ground level coordinates, scale factors, convergence, standard deviations and error ellipses with one click... and provides a concise report providing confidence in the results?

It is simply the best adjustment program that I have usedReview by Peter Haas, BCLS, FCS Land Services Limited Partnership
I have been using STAR*NET almost every day for the last 5 years. It is the perfect tool for combining conventional, GPS, and leveling data into a control network and checking the validity in a rigorous manner. The data input and interface elements make it quite simple to perform a least squares adjustment on any type of survey, large or small. (Posted on 4/24/15)
I look forward to using STAR*NET for many years to come on transportation control projectsReview by James E. Kovas, PE, PS, WadeTrim
Over the past ten years I've found STAR*NET software to be very consistent in handling raw data files for input to GPS, traversing, or leveling adjustments. The least squares adjustment algorithms produce reports that are easy to scan and identify network problems that need to be fixed. (Posted on 4/24/15)

Hardware Requirements

MicroSurvey STAR*NET operates entirely within Windows, and has no hardware requirements over and above those of Windows itself except as noted below. We suggest the following basic system as a minimum for efficient operation:

  • Pentium processor - 2 GHz minimum
