About

RGPR is a free and open-source software package to read, export, analyse, process and visualise ground-penetrating radar (GPR) data.

RGPR is written in R, a high-level programming language for statistical computing and graphics that is freely available under the GNU General Public License and runs on Linux, Windows and MacOS. R is a highly versatile and extensible language to which C, C++ and Fortran code can be linked and run. Furthermore, the R developer community is very active and more than 10'000 packages are hosted on the official global package repository CRAN (Comprehensive R Archive Network, https://cran.r-project.org). In 2017, R was ranked as the sixth top programming language by the Institute of Electrical and Electronics Engineers.

RGPR is hosted on GitHub at https://github.com/emanuelhuber/RGPR.

This R package is still in development, and therefore some of the functions may change in a near future.

To report bugs, contribute to the development of RGPR, see how to contribute.

How to install/load

1. Download R from the R Cran website and install it.
2. Optionally install a R-editor:
   • Rstudio (Recommended)
   • RKward
   • Notepad++ combined with NppToR
3. Open the R-editor (e.g., Rstudio)

4. Install RGPR

    if(!require("devtools")) install.packages("devtools")
    devtools::install_github("emanuelhuber/RGPR")
   

   Alternatively, you can download the package as a zip file and install it in R following these instructions:

Notes

Supported file formats (read only):

• Sensors & Software file format (*.dt1, *.hd, *.gps).
• MALA file format (*.rd3, *.rd7, *.rad, *.cor).
• ImpulseRadar file format (*.iprb, *.iprh, *.cor, *.time, *.mrk).
• GSSI file format (*.dzt, *.dzx).
• Geomatrix Earth Science Ltd file format (Utsi Electronics format) for the GroundVue 3, 7, 100, 250 and 400 as well as for the TriVue devices (*.dat, *.hdr, *.gpt, *.gps).
• Radar Systems, Inc. Zond file format (*.sgy). WARNING: it is not a version of the SEG-Y file format.
• IDS file format (*.dt, *.gec).
• Transient Technologies file format (*.sgpr).
• US Radar file format (*.RA1, *.RA2 or *.RAD).
• Geotech OKO file format (*.GPR, *.GPR2).
• SEG-Y file format developed by the Society of Exploration Geophysicists (SEG) for storing geophysical data (*.sgy), also used by Easy Radar USA
• SEG-2 Pullan, S.E., 1990, Recommended standard for seismic (/radar) files in the personal computer environment: Geophysics, 55, no. 9, 1260–1271(*.sg2). Also used by US Radar with extensions *.RA1, *.RA2, *. RAD.
• GPRmax: hdf5 file format with extension *.out (not well tested)
• 3dradar: the manufacturer does not want to reveal the binary file format *.3dra. Workaround: export the GPR data in binary VOL format (*.vol) with the examiner software -> still experimental
• R internal format (*.rds).
• serialized Python object (*.pkl).
• ENVI band sequential file format (*.dat, *.hdr).
• ASCII (*.txt): - either 3-column format (x, t, amplitude)
  • or matrix-format (without header/rownames)
• Terra Zond binary file format (*.trz) -> we are working on it

See tutorial Import GPR data.

Do you miss your preferred file format? Send me the file format description with a test file and I will adapt the RGPR-package to support this file format.

Supported export file formats

• Sensors & Software file format (*.dt1, *.hd).
• R internal format (*.rds).
• ASCII (*.txt):
• SEG-Y file format (*.sgy)

Coming soon

We are developing a new version of RGPR that will handle three-dimensional GPR data as well as multi-dimensional transformations, see our objectives.

Note that you can already interpolate GPR data (2D) into a 3D cube with the current RGPR version! Do not hesitate to contact me if you need more informations…
