Data Collector Training

Post by robodell »

I have been doing 3D laser scanning since 2014 and as our projects have gotten bigger we have found the need for a robotic total station to set our own control points. I have gotten plenty of experience setting up the total station and I am very comfortable with doing this. I also understand setting up where our nails with washers need to go and back sighting and all that fun stuff but where I'm falling short is the data collector. The person training me used to do land surveying and told us he could train me but I have found he is unsure of himself and constantly second guessing what he is doing which in turn makes it extremely difficult for me to learn. I have come to the point where I need to find an outside source to learn how to use the data collector and other valuable surveying techniques.

Is there somewhere I can learn how to use the data collector online for what we are doing? I'm looking for something that allows me to practice while watching a video or reading the lesson. We are using a Trimble S6 and a TSC3 data collector.

Thanks

Hi Robert.

Did you get your kit through a Trimble Dealer? If so, you should try contact them to arrange for some trainign material. There is also a controller emulator you can download to your PC so that you can have the total station on your desk (or setup on a tripod next to you) and then use the emulator to mimic the controller. This is handy for testing Control Codes and other controller functions.

What exactly is it that you are struggling with on the controller?
I have the same kit setup as you, so if you explain what you are struggling with I can try help. Feel free to private message me if you wish.

Hi Jared.

We got our equipment through a 3rd party. Basically I'm not getting any time or training on using the data collector so I need the step by step instructions from powering the unit on. It's been a while since my co-worker has used the total station so he tends to talk out loud when he is setting things up in the data collector but I can't see what he is doing. Unfortunately we aren't that busy right now so I am able to take the equipment home with me and practice but I just need to know what tabs to be in to record the data properly. The only one I've really been allowed to mess with is the tab where we change the prism from a 360 to a standard one. I don't think we have any codes setup in the collector since we are only using this to set internal control for our laser scanner. We create names for our spherical targets and our checkerboard targets are already named. I think I've heard him mumble BS=Backsight, TRV=Traverse, PT=Point, and TRG00 for the spherical targets.

I hope I provided enough info that explains everything clearly. I wish some of the technical colleges around here had weekend courses or workshops. I may just have to reach out to some survey companies in the area and see if they need some free help in exchange for some training. :lol:

There are plenty of videos on YouTube. Try searching on Trimble Access and S6. The TSC3 is an older data collector so some of the older videos may be more useful to you.

Personally I like to have Survey completed by someone different than the scanning. This lends a level of redundancy and secondary checks.

The Survey I'll do myself is to set a group targets all at the same level by Rotary Laser. This can be used to verify the z values and insure the scans are not tilted.

I studied Geomatics and worked as a Geomatics and Survey Manager for more than 20 years. When I started the shift to LaserScanning and introducing LaserScanning to our teams back in the early 2000's we consciously separated Survey from Scanning. And to this day, I still keep Scanning separate from Survey. The Survey are secondary checks on the scanning, and thus are better left to a third party or at minimum a different team from within the same organization.

Especially if you are looking for millimeter tolerances and closures. There are many very specific principals and methods in Survey that can't simply be taught on videos. You even mentioned prism constants. Which are not straight forward. You need understand differences between Nodal and Non Nodal prisms. A standard 30mm prism is entered as -30 on some instruments, +30 on other instruments, and +4.5 on others... And then the way you setup your Data Collector communication between the total station can have drastic impacts, as some you enter in the total station, and some in the data collector. And although that sounds small, but an error in prism constants can easily cause errors well into the inches.

If you really want learn properly. Take a 6 month leave, and go work as a Survey Assistant on a Construction Layout crew. I say Construction Layout, as Legal Survey is much more focused on definition and finding of legal evidence. But if you get in with a construction layout firm, where you are visiting different construction sites daily, you'll gain great knowledge in a 6 month period.

Basically. No. It is not simply learning the menus. There are many nuances in survey. Just like a since a person registers data in Faro Scene does not mean they'll be able to register data inside of Cyclone. Laser scanning has it's nuances as does survey. And these things are not learned via videos.

Honestly. Bet solution, go work as Survey Assistant for a construction Layout firm. It is your fastest and best method to learn what you'll need know. At least 6 months as an assistant will give you some fundamental roots to start learning how to properly use the Total Station and data collection.
