The surveyor I work under does not have a clear understanding of working with GPS or using Grid Coordinates. When I started working for them a few years ago everything was all total station and levels from Geodetic or hiring someone for a couple GPS points on the sites we did stakeout on. Until recently we had not planned on changing that. Now after a demo from a Survey Supplier we are getting some Carlson Rovers to be used in place of the total stations for some of the work.?ÿ
After some recent conversations it has become apparent that they intend for me to be the one to learn all the ins and out and how to process the data into recordable maps.?ÿ
I recently graduated from an Associate's program in Land Surveying but we did not go very deep into this topic beyond what might be covered on a board exam and some field procedures. I have used GPS before but never in an application like producing plats.?ÿ
I feel that I could learn the procedures to do this task but I do not feel comfortable enough with it at this time.?ÿ ?ÿ ?ÿ
How should I approach this topic professionally??ÿ

Make sure that your company provides you with all the training that you need. If you do not have a clear understanding of the equipment, when and when not to use it, how to use it and how to process the data, you are only going to create problems.
You have the opportunity to say this is what I need to become competent. They are not competent and can't teach you. If you want someone to take the initiative to make you competent, you will probably have to go somewhere else. If you have the initiative to make yourself competent, then this is the perfect opportunity. Dive in and make it happen or wait on someone else to make it happen for you.
Grab the bull by the horns and make yourself valuable to that company and anything that may come in the future, if you so desire. You just got out of college so your brain is already in the right mode. Don't wait till down the road when things may be more difficult. There are Chiefs at my current company that have been at it for 30+ years and they can't even spell GPS. It's quite sad. There's plenty of training and help out there.
They better be willing to pay for every minute of training you need, as well as throw in a nice big pay bump for you taking this on.
As a side not, I'd be more than a little concerned about a licensee who thinks "oh I'll let an employee learn this decades-old industry-standard technology rather than learn it alongside of them".
@jflamm I am fully willing. I just know what I don't know.
@rover83 They have not mentioned much in the way of training besides the free jump start session the supply company provides. I am not really as worried about the field procedures as the office work.
Just about any surveying work you'll encounter is going to require a working knowledge of using GPS. Old school conventional is also important but these days the emphasis is on the efficiency GPS brings to job. A good book to start with is GPS for Land Surveyors by Jan Van Sickle. It details the different methods used. This site is also a good place to ask specific questions. It's good to put yourself out there and learn but know that like any tool, there's always different ways of using it and it's in the understanding of the tool and they systems behind it that you develop the knowledge to know when and how it's appropriate to use and the limitations that come with those various methods.

I find the USACE manuals to be useful as they are written to teach often under prepared learners. Lots of good free presentations on GPS/GNSS. I recommend Eric Calais’ when he taught at Purdue.
obviously you need to study the materials provided by your equipment manufacturer.
You also need some background on geodesy.
You do need a basic understanding of what the satellites are doing, what data you receivers are collecting and what calculations and conversions your data collector is making. There are a handful of good correspondence courses out there. They are mainly for continuing education credits, but they do provide the basic idea. There seems to be more things that will degrade your position using GNSS than with conventional total station data collection. You need to formulate a good procedure for verifying that the data you bring into the office is correct. Some sort of supplementing your Single Base Line RTK with Static GNSS, Conventional Control, or Network RTK. Good Luck.
I'd be hard pressed to teach myself GPS if i started GPS work today. You definitely need someone that has done it before to show you the processes and procedures. GPS configurations and coordinate systems and scale factors can be very efficient or create more of a mess than anyone can fix.
Not all that long ago we had received data from another survey firm for a municipal project. It was clearly done with GPS and things were going along just fine until we checked into some of their primary control points and missed by 5'! Other points were spot on, the primary control wasn't. To make a long story short they scaled the project data down to ground using a central project point (I despise this method with a passion!!!) but did not scale the primary control points. There were other systematic issues as well, but that was the big one. And....they had been using GPS for over a decade but had no clue of how to properly setup project scale factors and admitted as much to me along with a story of how they almost owned an apartment complex because of this issue on another project.
Getting off topic here but you really need to learn from someone who knows the ins and out of your equipment in the office and the field.
Hi I saw this post. Before I give you a good solid answer (opinion), may I ask some questions ?
So, you're using Carlson "rovers" ? or is it s Base and Rover ? Next off, what software and data collector has been provided ? and thirdly, there is mention of "grid" coordinates. Does this firm intend to do maps in state planes coordinate values with a scale factor and rotation angle ? Etc or are the surveys simply ground, straightforward maps / topos etc ?
Please get back with me. I'll do my best to give you some answers and direction. Just being tossed into the lake and told to swim is NOT a good beginning.
Thanks "Good"
can be very efficient or create more of a mess than anyone can fix.
That is so true.
I've been doing it for over 10 yrs.
And I'm still learning.
Not to scare you, but I honestly suggest you work with someone who knows it well, for a month or two.
There are many basic things that are best not learned "the hard way".
I'm super pedantic, and double check all things that show signs of needing it.
And, mfr's don't all approach the same problem from the same viewpoint, or mechanism in their software.
Get a good mentor, even for a day a week, and you'll not regret it.

they intend for me to be the one to learn all the ins and out and how to process the data into recordable maps.
What office software is currently in use with this surveyor?
Learning it all at once could be a challenge. Do you have any experience with any kind of drafting software?
This is alot to learn.
