So I'll dial down the centering errors until I get a pass. I figure that some day some lawyer might latch onto that lower bounds fail without appreciating it's true meaning. I don't like to have a statement about exceeding bounds one way or the other. If it exceeds the upper bound then I look for my stupid mistake I can't see for the life of me even though it is staring right at me. If it exceeds the lower bound, I don't worry about it. On the other hand if I put in 1.00 centering errors it exceeds the lower bound: Network Adjustment with Error Propagation It exceeds the upper bound with zero on the centering errors: Stations Semi-Major Semi-Minor Azimuth of

Some manufacturers even provide STAR*NET converters for their own data, because STAR*NET is the most widely used Least Squares Adjustment program.Īvailable in four editions, MicroSurvey STAR*NET has different options to suit your budget and needs.Copyright 1988-2011 MicroSurvey Software Inc. Then, the final results can be sent off to MicroSurvey CAD, AutoCAD® or popular COGO programs.Ī large number of converters are available to process measurements and GPS information from TDS, Carlson, MicroSurvey, and more. With computed error ellipses, angular closure errors, easy-to-understand adjustment statistics, a preanalysis routine and a blunder detect function you will be able to identify and stamp out every single weakness in your survey network.
With a graphical display of your entire survey network, you will find it easy to tighten things up. There is no other Least Squares tool available that is as comprehensive as STAR*NET. We know what you need to complete your tasks, calculations and drawings.
MicroSurvey has been working with (and building tools for) surveyors for over twenty years.
STAR*NET comes in several editions: Lev, Standard, Plus, and Pro, plus a number of handy conversion utilities, to ensure you get precisely the tools you need. Angular measurements are supported in both Deg-Min-Sec and GONS. 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.Ĭustom Transverse Mercator and Lambert grids may be defined for special local requirements or for grid systems in most areas of the world. 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. Differential levelling observations can also be included within a 3D adjustment. STAR NET handles networks containing conventional observations combined with GPS vectors, with up to 10,000 adjustable stations.
MicroSurvey STAR NET 9 is an easy-to-use Windows application that adjusts 2D/3D survey networks using rigorous Least Squares techniques.
