GPR for Archaeology

Collecting, processing and interpreting ground-penetrating radar (GPR)


GPR Software

GPR Process: This is the workhorse for GPR processing that make the amplitude maps.  It must use reflection profiles that are in .dzt format (GSSI).  We now have the ability to convert Mala, Sensors and Software and soon IDS profiles to .dzt format within the GPR Viewer software (linked below).  The instructions on how to do that are in the GPR Viewer manual at the very end.  

Click on the highlighted links below for the software and instructions, which are zipped together for the amplitude re-sampling and slicing software: 

Sorry…downloads are blocked by my web server.  The host company is NO help at all with this, so please e-mail me at lconyers@du.edu and I will ftp you the software downloads.

GPR Viewer: This program will process individual reflection profiles.  This recent version will open SIR-4000 system files (as long as you have those .dzx files in the same folder as the .dzt files!).  You can then save them as other formats, such as Sensors and Software or Mala Files.  I use this new Viewer file to open SIR-4000 files (I don’t yet have a 4000 system) and save them as dzt files from the SIR-10 days (this is old-school, but all the data are still there).  This is important for some of us as the GPR Process program (above) will only process the SIR-10 version .dzt files.  I know….I need to update that slicing software, but have not gotten around to it and the time it takes to just convert files to the SIR-10 format is much less than re-writing the software.  And I am not making any money on this software, so what is the point?

GprViewer:

re-gains profiles, remove background, change scales and convert times to depth

  • adjust for topography, calculate velocity from hyperbolas and do other common processing steps

  • produce images of profiles for publications

If you convert SIR-4000 or Sensors and Software or Mala system files to SIR-10 format for slicing, there is a little trick in the software that forces you to have your files named file1.dzt, file2.dzt etc.  You can very quickly just change their names in batch mode using this free app, which I use all the time: http://www.bulkrenameutility.co.uk

We also have a number of other software programs that do data processing such as migration and frequency filtering. Here are the instructions that you can read first to see if you are up for this or not.  Many users are NOT

using DOS for frequency filtering_and_migration

This is a map showing how some of these processing programs can significantly clean up and enhance reflections prior to slicing and producing images.  You will have to write me for information about these more esoteric programs.  See some slice maps I produced below that illustrate what can be done with this type of data processing: other_programs
