Least squares adjustment gives us this solution, allowing us to catch errors accurately and with confidence,” Durnin added. “All measurements are propagated from your control, so having a robust solution on which we (Murphy Surveys) can rely is the bedrock of our methodologies and protocols and how we achieve precise results. “It’s the basis of our quality (in surveying projects) and the part of the fundamentals from which our precision on surveys is quoted,” Durnin explains. But now, STAR*NET has made this capability more versatile and powerful. “It’s very useful, and completely changes the approach and analysis I take with my network plots because I can more easily distinguish the types of observations in my networks and check for completeness and redundancy more easily.”Įstablishing network control and checking it is a fundamental task on all projects. Michael Durnin, survey manager and technical manager with Murphy Surveyors, global consulting surveyors with offices throughout the UK and Ireland, and a STAR*NET user for 15 years, considers the new Network Plot Manager a valuable capability. And, users can now use their mouse to smoothly zoom and pan within the network plot. Directional linetypes indicate the direction and number of observations between each network station. The network plot can be customized in an intuitive grid view that allows users to control the visibility, color, linetype and size of each network element to graphically differentiate conventional, GPS and leveling observations. “In fact, nearly all of the new features built into it came directly from requests in MicroSurvey’s Request Forum,” Sloman said.Ī main feature of STAR*NET 8.01 is a new Network Plot Manager to control your observations. But the new version seems to have something for everyone, suggests Brian Sloman, MicroSurvey’s Desktop Products Manager.
Different users will have different reasons to upgrade to this improved software package. Striving to make the software even better, MicroSurvey has just unveiled version 8 along with a massively updated version 8.1. STAR*NET, which MicroSurvey acquired from Starplus Software in 2010 and has since offered through numerous upgraded and improved versions, is well adapted to help its users perform least squares adjustment with confidence. In other words, it’s a way to process all of your measurements simultaneously to achieve the best, most precise results. Keep in mind that least squares adjustment is a processing tool in surveying, really. While not the only software program available to accomplish least squares adjustment, MicroSurvey STAR*NET has become one of the most popular and routinely used packages for this important method. The desired result is to get adjusted coordinates that are more reliable and accurate compared to those obtained from simple intersection and traverse adjustments. This method can accomplish several key steps: solve resections, adjust a network, adjust traverses, hunt down blunders in the data you’re observing, blend GPS vectors and total station work, and differential leveling data into one project. Least squares adjustment can be applied to something as simple as a resection or a more complicated situation such as a three-dimensional network. The best way to confidently accomplish this objective is through a least squares adjustment. Since time truly is money in the surveying business, the goal is to reduce random error inherent in survey measurements. I have never gotten a file out of the converter that I could use without some editing.For most surveying projects, speed, efficiency and accuracy of measurements are paramount. Some jobs deep in the forest don't have GPS so I will use a record bearing on one of the lines as a fixed bearing along with a fixed assumed coordinate. Usually the coordinates in my field created raw file are throw-away guesses which I edit later using a coordinate from OPUS or something like that.
Ron Sawyer's version of the manual says you can enter either one meaned observation (use a smaller standard error) or all of the set pointings individually (but use a larger standard error).
It converts RW5 files and is supposed to be able to create one M line from a multi-set but it doesn't work it makes a series of SS records. I'm using the old TDS converter (pre-MicroSurvey).
Using *** between the elevation and code lets StarNet know that is a free coordinate that can change as much as necessary.
It may require a provisional coordinate for the unknown station. Isn't a resection just a multi-set from an unknown station to multiple targets? I would think you just put that into the DAT file as M lines then process it.
