Hi All,
As I keep repeating on every post, I am very, very new to the world of surveying. I'm an archaeologist and I recently purchased a Leica 1250. The goal is to use RTK to just get the coordinates of ground control points for projects. Nothing fancy.
Using this website, and a lot of swearing, I have paired my 1250 to a old Bluetooth phone, signed up for RTK and apparently am getting 1-3cm accuracy, which for my purposes is amazing!
My only issue is, I just can't work out how to export the coordinates of a point to the CF card.
So I will open the survey application, give it a name, store the point. Then try to export it to the CF card as a txt file. All I really want is a list of the points taken with their corresponding X,Y,Z coordinates.
I have gone through the manuals but can't for the life of me get it to produce these results. I can get data out, but normal just a few things like height, GDOP etc.
I know I am missing something critically simple, but can't for the life work it out.
If anyone uses these systems in Sydney, Australia and would like to give me an introductory course- I will pay or just bring you beer. For everyone else, if you can help me sort this out, it would be amazing.
Once again, apologies for the newbie question.

Not at all, the newer Leica systems make it easier to export a basic ASCII file.
On this system you need a format file. Unzip the one attached. Put it in the CONVERT folder on the CF card.
Then with the CF card back in the RX1250 logger use Tools > transfer objecs to transfer the format file to the internal memory of the logger.
When you use Convert > Ascii the format file should now appear in the list.
The one attached will give you grid coordinates only (ie eastings and northings) so you will need to know that you are in the correct coordinate system.
Let me know if the FRT file does not work, it actually from an older system but I think should be right for your software.

Hey, first off, thanks so much for this! Unfortunately, it doesn't work. It transfers properly but says "Data Conversion has Failed. It is possible that the format file is damaged"
Yes, ultimately all I need is easting and northing and height above sea level.
The next thing to learn is the coordinate system. As I am going to Greece, I have been sent the file HeposGrid_Field.csc and metrica_geoid.gem files. I now need to learn what these do, so if someone can give me a simple explination that would be amazing. Only issue, I tried to trasnfer the Heposgrid file to the machine and it says I don't have enough memory.
The problem with me is I am coming into this blind, so slowly researching and trying to get my head around the whole field. The good news is, when I get to Greece I should have a few days to just research and read and play around with it.
Hugh aren't you going to call your points something?
I'd definitely give each point a code = description.
That way you don't have to scratch your head later and wonder what's what.
You at least (IMO) log points with codes.
Then export Pt No, x, y, z, Code and with timestamp, and positional accuracy.
I've found it invaluable to have all that.
I would have expected a file format like that to be in there, somewhere.
But as mentioned I have limited experience and that's with GS14.
I'm sure squowse, or others will chip in, correct me.
Hi,
Yes sorry, I think I didn't explain it 100% properly..
I will be surveying in ground control points in fields. So I will give each field a job name ie Field 10, then each point will correspond to a target which will be numbered say 1-6 or whatever.
What I want to do is export the fields I do that day and for each have the data say
Point Number, X/Y/Z, timestamp and accuracy. As you said.
Unfortunately, because this is a second hand machine, I think the FRT tile may have been removed or something. I just have no idea how to get it back. I know the data is being collected as if I look at the data, and click edit, I can see the coords. But none of the 3 FRT files on this seem to export that data.
So if anyone can help, that would be amazing.
I really wish there was a book for dummies on this stuff. haha. I am an archaeologist dropped into a surveying world and it is strange and different haha.
Thanks for any help guys!
Try this one specifically for 1200 series.
It will be possible to get the other details eg accuracy, timestamp but will need a bit of research on how to edit the FRT files.
you would need to google "edit leica 1200 FRT file" or similar
The two coordinate system files are correct. They need to go into the following folders on the Cf card
Data/GPS/CSCS for the csc file
Data/GPS/Geoid for the gem file
You will also need the projection details, create a new coordinate system with these details and choose the two files above for the shift grid and geoid respectively.
Or if you have a TRFSET.DAT file , this contains the projection details
Put this in the DBX folder , transfer user objects (coordinate system) and the coordinate system should appear in the list.

Hey, firstly, thanks so so much for all of your posts. I think the file you sent works. I have noticed that my results might be 0,0,0 or something and I am wondering if because I haven't applied the Australian geoid etc, maybe this is what is giving me a negative results when trying to export, despite having the coordinates when I 'edit' the data files of points. Do you think that could be my issue? So I think I will do some testing on Tuesday and get some Aussie files like the Greek ones and see what I can do. My problem is this system is from Germany, so it's loaded with german files that are useless.
As for the Greek files, yes I have the TRFSET file and the others, I will try upload them on Tuesday, but obviously, they won't help till I am there.
Thanks so much for your help and if possible, could I contact privately with some questions as I am guessing you are as Leica 1200 expert!
I'll report my results here when I am b
