dear brothers
I'm trying to find help to solve my issue
I'm working to do the total station travers for establishing new BMs' ground coordinates
Depending on 2 official BMs (known points) as a baseline, by totalstation i measured all other new points by distance and angles (redundancy) from each setup to any point I see it ( some point 2 measuring, some 3, some more....etc) and i need to process the traverse as a least squares adjustment method, and the avalible software is (1- Leica Infinity, 2-civil3d, 3-MicroSurvey StarNet 9 (cracked) , 4-Carlson_Survey_Embedded_2016.
The question is :
- Which software is easy to do this process ?
- and how can I prepare this data to insert it to the software and get the processing report?
I'm really appreciative of your help!
Carlson Survnet will do the job and is probably your cheapest option. StarNet is my favorite because I've been using it for nearly 30 years. It is a great way to combine data from various makes of data collector. Lieca will be a good choice if you are using all Leica gear and always will. It is also best if your network will cover a very large area - like your entire country.
If your goal is to simultaneously adjust GNSS vectors and terrestrial traverse data then Civil 3d is not for you. C3d will not work with GNSS vectors.

Thank you for your great information
Actually I've tried so much to insert my data into Star*net, but i don't understand why I'm getting an error! im tried to find torture videos on YouTube but nothing!
can you please show me how i can insert my data in an acceptable way to Star*net ? or even if you recommend another software to me? like civil3d,carleson,N4Ce, leica infinity, ...etc ?

If you attach your data file to your next post, one or more of the resident Star*Net gurus will be irresistibly compelled to troubleshoot it for you.
Here is a StarNet data file that I prepared just yesterday. It has both GPS vectors and terrestrial traverse data in it. The site is in Oregon, USA. So to run it successfully you will need to set your grid system to Oregon State Plane of 1983, North Zone, Oregon Coordinate Reference System (ORCS) Portland Zone, or UTM Zone 10. Units of International Feet.
Perhaps you would like to post the data you have and we can take a look at it. Or maybe just start with posting the error message you are getting.

One of the advantages of StarNet is that it has been around a long time without changing much. So there is a large base of users who are familiar with it and can therefore help you. You don't get that, quite as much, with any of the others.
Starnet has a demo version that might give a try.

THANK YOU FOR YOUR REPLY
Im attaching the Excel file which includes the names of known points, which will be as a baseline (with coordinates)
and other data which are the stations and measurements (distances and angles)
Every station has a first distance to the first point with an angle of 000
and the other distances for other points with angles DMS
and like that redundancy
i don't know why i cannot attached the excel file

great job sir
how i can arrange my data just like your file ?
can you help me please
how i can arrange my data just like your file?
By converting the raw data file from your collector using the conversion utility provided in StarNet.
Please tell us about the data collector and software you are using to collect your GPS and terrestrial data. Knowing that we can provide you with more specific advice. I appears that your data is 2d only. Thats OK. If you are recording with book and pencil that is OK, too. It will just take a little longer, but probably no longer that it took to put that spreadsheet together.
Are the distances noted in meters?
Finally, what is the appropriate projection grid system for your area?

Good morning Mr Norman_Oklahoma
Let me lay out all the information to clarify...
The new BMs observed by GNSS static mode depending on the client's official reference BMs network (grid coordinates). so ... i need to convert these new grid coordinates to the ground coordinate to be accepted for total station work, because now it is a grid coordinate with scale factor ( UTM S.F 1.000122141615 At datum location ). The purpose of traversing by total station is to converting these grid coo to the ground coo to be with scale factor 1
So now :
1- I have these new BMs with grid coordinates ( S.F 1.000122141615)
2- I have 2 corrected points (S.F 1) which will be as the baseline, from these 2 points i used the total station to measure distances and angles D.M.S
3- my measurements as a redundancy, from each setup i measure ( distances and angles) for all other points, and in the next setup I also measure again all the points ..... etc
4- that is mean only the first TS Setup which is identified with the known coordinates ( baseline coo), the other setups are done by setting the previous point as a 0 00' 00" angle and continuing....
Please tell us about the data collector and software you are using to collect your GPS and terrestrial data.
I collect the total station data by hand recording.
I appears that your data is 2d only.
Yes i need only 2D least squares adjustment traverse.
Are the distances noted in meters?
Yes all meters
Finally, what is the appropriate projection grid system for your area?
- Official Name: AR RATAWI Project. This datum is equivalent to the ITRF 2014 epoch 2022.2
- Spheroid: GRS 1980
- Projection: UTM 38N
- Vertical Datum: EGM 2008
Finally.. i appreciate your cooperating
i can send you all the data by email if you don't mind
I took a stab at this and input the data into Starnet. I left the adjustment on local, distances meters, and made some instrument settings assumptions.
Very nice. I have never used Starnet. I have PCSurvey and it has a Least Squares option. I entered this data but I just used the standard error settings and got the same adjusted coords within 0.02m except on N3 and AR-2-10 I differed by 0.04m.
Yea, I was looking at my input and realized while I was doing some trial and error I left the last data record marked out. I will re-run the adjustment with it included and repost the results.
I just keyed the data in and it did not take long at all. Starnet has so much flexability to combine different data sources and do some complex modeling and adjustment or just a quick 2d adulstment as this seems to be.
Are you able to apply set up error for instrument and bs/fs in PCSurvey?
I used 2mm for the instrument and bs/fs and 2mm 2ppm for the instrument. Just took a guess as to what those numbers really are. Starnet provides an online calculator where you input how many sightings bs/fs you make, what the instrument set up errors are, bs/fs setup error and edm specifications. It then computes the proper statistics for the least square adjustment.

Here is the revised adustment with that last data line included. I sorted the adjusted observations by the residuals so you can see what is being adjusted outside the set parameters.

Outstanding job, Gary. Thanks.
One quibble. I like to fiddle with the a priori error estimates until I get close to 1 on the combined error factors. That won't change the final coordinates significantly, but I like to know just what the precisions were. In this case I think that an angular error of 5 seconds and distance constant error of 0.003m would do the job. And may be in keeping with the instrument Mohammed is using.
I did not rerun the data and yours changed very little so we still differ by the same amount. My default settings were 0.00 on centering and target error, 3" on pointing and circle error. I compared 8 adjusted angles and we differed 2-5". I compared 8 adjusted distances and we differed 0.00 to 0.03m. My control networks have never been complicated so I have been able to adjust my data using Least Squares on PCSurvey and then traverse manually for a check. I am sure that it's my results that need tweaking and I really appreciate being able to compare my results against your more rigorous Starnet results. It gives me confidence that my software is calculating a good adjustment. Thanks again.
thats awosome friends
Thank you, Mr. Gary, for your report!
i want to show you my processing job by Civil3D, because there is no LSA in Civil3D, i take the average point for each station and then i make the closure traverse by Civil3D
But compared to your data, there is some confused differences
Take a look at this screenshot:
comparing betwoeen you v1 and v2 report with my civil3d closure traverse
what is your opinions sirs ?
@norman-oklahoma I do the same to some degree. But I also don't want to start changing values that I'm assuming are being met in the field. Most of what I adjust are 3d traverses so i adjust the zenith angle standard of error a bit. I don't adjust the edm standards at all and rarely the horizontal angles. a lot of times I start with what the online calculator gives me , run the adjustment and then just round the odd value up to a whole number.
If I pass the chi-square I am confident my work is within the standards I set and my error ellipse on the adjusted points are realistic and not scaled up by the combined error factor.
As far as the actual instrument capabilities I could only guess, and were the angles turned once or how many sets, and distances were actually measured. I made the assumption there is some averaging in his final data he presented. I think 2mm and 2ppm for EDM is close and the 2 second instrument is good. set up errors are close to what I use.
