Simple (-ish) Ground Penetrating Radar software

rsgpr — Speeding up Ground Penetrating Radar (GPR) processing

The aim of rsgpr is to quickly and accurately process GPR data. In one command, most data can be processed in pre-set profiles or with custom filter settings, and batch modes allow for sequences of datasets to be processed with the same settings.

Thank you to the creators of RGPR from which the name and functionality where both inspired.

This is still an early WIP, and currently only works with Malå (.rd3) radar formats.

Possible meanings of the name

• Really Simple GPR
• rust GPR
• rsgpr simplifies GPR

Installation

Requirements

• cargo for installing rust projects
• gdal bindings. For Debian or derivatives thereof, this means libgdal-dev.
• proj bindings.

Using cargo, rsgpr can be installed from the repo (after installing the requirements):

cargo install --git https://github.com/erikmannerfelt/rsgpr.git

with nix, the flake can be used without worrying about the requirements above:

{
  inputs = {
    rsgpr.url = "github:erikmannerfelt/rsgpr";
  };
}

or in an ephemeral shell:

nix shell github:erikmannerfelt/rsgpr

Simple usage

See the help page of rsgpr for info on how to interact with the CLI:

rsgpr -h

To toggle useful information on a file, the -i or --info argument shows the metadata and a summary of the location data:

rsgpr -f DAT_001_A1.rd3 -i

Processing a file using the default processing profile:

rsgpr -f DAT_001_A1.rd3 --default

The output will be a NetCDF file with the same name but an .nc suffix. By default, the output is saved in the same directory as the input. For more control, the output directory and/or filename can be controlled with -o or --output.

To process multiple files in "batch mode", provide a "glob" pattern as the filename. Optionally, for many sequential files, the --merge argument allows merging multiple files into one.

rsgpr -f "data/*.rd3" --merge "10 min" --default -o output/

A rudimentary profile renderer is available with the -r argument. This will be saved in the same location as the output file as a JPG if another filename is not given.
