In this Tech Talk we discuss a useful solution for road stakeout utilizing Trimble's Integrated Surveying methods. This video will demonstrate how to perform a Station Elevation using a known benchmark elevation which is a much faster and more flexible way to setup your total station when measuring elevations is your main objective. Once the instrument is elevated, we utilize the Precise Road Stakeout option to stakeout horizontally with our GNSS rover & vertically with our robotic total station.

What version of Trimble Access are you on? I’ve been having issues with integrated and Trimble Access 2022.01. I’m not able to measure a point or change design elevation.

This is most likely v2023.00 based on the date the video was uploaded

Ok , let me say this. Frontier Precision is one of the coolest company I have been lucky to be aware of exitence . Now this video is a bit weird. Whatever the guy is doing is right, in the right fashion ecc. But this video can t be sold as "precise road stakeout with station elevation". I know u people would like to , but gpses are not precise, and they will never be. U can try to define a certain level of accuracy doing this hard aproximation of the flat to the curve yes, that is what the gps is for , but if u want to call this video precise road stakeout , u better start talking about setting up the instrument on a CP that belongs to a traverse (or if not , then u need to use statio elevation computing residuals from CPs ) shoot some other station using station setup plus and chack discrepances or residuals on that point. Or a three point resection. Even a free station setap will be better as long as we have control on site . This is the precise way to do the job. Is it accurate? Depense on may factors , from gps to edm, temprature, refraction ....not to mantion that if u need it precise my friend , u better start talking about angles and distances. All of this video has nothing to do with the term PRECISE. I know u can build up a resection with control points using integrated survey, view the sigmas "of the sample" but yet how big is the site ? what s the best time for gps obs? Are my cp Covering THE SURVEYED AREA in the best fation? How do behave this gpsed points from integrated survey when we move far form site, and the station set up point comming from them ? is the flat to curve working properly? For a good job to be precise and accurate traveresing can not be skipped , sorry. I am sorry to say, and to remind people that LSQ adjusment done in real time ad taken as they come in from your controller are dangerous to be used .

Thank you for the comments and questions. You bring up some very valid points that all surveyors should be aware of when thinking about precision and accuracy. I'll preface by saying the purpose of this video is to demonstrate one of the ways that you can utilize what Trimble refers to as "Precise Elevation" staking using the Roads Module. The option I'm referring to is shown at 0:44 in the video. By enabling "Precise Elevation" stakeout, it allows the user to utilize a robot for elevations while staking horizontally with GNSS. When considering an integrated survey style workflow, the user has the option to set up their instrument via Station Setup, Resection, Station Elevation, etc. Determine what's best for YOUR scenario. Yes, a Station Setup or Resection is preferred, but sometimes the user might not have the ability to perform a Station Setup or Resection whether that's due to lack of control or line of sight issues. Or maybe they just don't need to waste their time doing more than a station elevation routine, which is exactly what I demonstrated in the video. There are times where a GNSS solution will give you an acceptable horizontal position but not good enough vertical. That's where the robotic total station comes in. Bottom line - the Station Elevation routine allows you to quickly setup the robot for precise elevation staking by simply localizing in (benchmarking) on a known elevation. From there you're only using the robot for elevations. The GNSS is giving you your horizontal location. If you want precise horizontal and vertical, then a true station setup or resection would be the route to go. Thanks again for your comment and bringing forth a crucial topic.
