How is the GPRPy input file created?

[GokcenMerve]

Hello,

I'm a young engineer and I'm interested in ground radar. I saw your work and wanted to try it. I did the uploads as described. However, I did not fully understand how to use it. I have a few questions that I hope you will answer;

1. How do you create .dzt files?
2. After creating the .dzt file, which command do you write and run at the command prompt?
3. Do you have a .in file to create a model? Or is the input file of the model already created in .dzt?

Best regards,
Gokcen.

Hi, thanks for your interest in GPRPy!

This is a software to process and display ground penetrating radar data. It currently can not create synthetic data, but that would be a great feature to add. So to answer your questions:

1. The .dzt files are created by a GSSI ground penetrating radar system. GPRPy can also read the files created by other radar systems such as Sensors and Software (SnS) etc. At this point, I included some demo files with the software but there are more files available here: https://github.com/NSGeophysics/GPRdata
2. You can load the data files using the graphical user interface, which you can run from the command line after installation following the instructions here: https://github.com/NSGeophysics/GPRPy#running-the-software
3. At this point, GPRPy can not create synthetic data. It is purely a processing and visualization tool. But it would be great if someone added modeling capabilities.

Best wishes,
Alain

Hello,
Thank you very much for your reply. Once I've experienced the data you submit, I'll write to you for results.

Yours truly,

Hi Alain,

You said "The .dzt files are created by a GSSI ground penetrating radar system. GPRPy can also read the files created by other radar systems such as Sensors and Software (SnS) etc." but unfortunately I didn't understand how the files were created. I can view your shared .dzt files via the command prompt. But when I want to create it myself, I don't know how. Do I need to modify .py files in toolbax? I have also reviewed DZT.File.Format.6-14-16. Are these parameters used when creating the dzt file?

Yours truly,
Gokcen

Hi Gokcen,

To create a .dzt file you need to either borrow or buy a ground penetrating radar system from this company: https://www.geophysical.com/ The files contain the data that were collected while using this system.

There are likely some software packages around that can create synthetic radargrams, but their output is probably not a .dzt file, but perhaps one of the other compatible files that can be loaded into GPRPy.

Best wishes,
Alain

Hi Alain. I want to add support of ASCII text file (X;Y;amplitude).
Data example:

X;T;ALg_10;
0;0;59983;
0;1;59983;
0;2;59981;
0;3;59981;
0;4;59981;
0;5;59983;
0;6;59989;
0;7;59997;
...

Correct me if i wrong: 'data' is a numpy matrix of traces, where every trace is separate matrix.
But what i need provide as 'info' in case of my data?
Maximum possible depth in my case is 4096 ns (vertical resolution 8 ns, so every trace have 512 amplitude values).
Here is file example 1.txt
