RIS MF Hi-Mod: Ground Penetrating Radar (GPR)

         
   

RIS MF Hi-Mod
Benefits

   
         
   

End to end procedure ensuring professional results in mapping underground utilities and anomalies;

High productivity with specific software tools for automatic target recognition and transfer to CAD/GIS maps;

Highest detection percentage level, combining longitudinal and transversal scans and several frequencies;

Modular array, easy to set up and reconfigure in the field;

   
         

 

RIS MF Hi-Mod is a specialized ground penetrating radar system capable of investigating large areas with a 3D view of the subsoil with a high capability of resolution and penetration depth. Thanks to the radar's capacity and the archaeologist's experience buried underground objects can be detected with a high level of confidence and consequently plan the excavation activities. RIS MF Hi-Mod offers:

  • Consolidated complete procedure from field acquisition to the final output (maps on CAD or GIS);
  • Mechanical structure for all urban environments and terrains;
  • Automatic target recognition: automatic tools help the operator locate pipes and cables;
  • 2D & 3D tomography: optimized tomography for an immediate visualization of pipes and cables;
  • Multi-frequency data fusion: automatic fusion of data from 200 and 600 MHz antennas;
  • Automatic transfer to CAD/GIS: localized pipes and cables automatically transferred to CAD or GIS maps.

The RIS MF Hi-Mod GPR solution is equipped with an array of multi-frequency antennas to provide a high resolution survey of the shallower depths, using 600 MHz antennas, while guaranteeing a great depth range with the 200 MHz.

Why use an array of Antennas?

  • to correlate information coming from several data channels;
  • to accurately reconstruct the path of underground utilities in complex situations;
  • to ensure accuracy and productivity. An array scan is much more powerful than many single antenna scans.

The RIS MF multi channel - multi frequency data is processed with a dedicated software to fully exploit the system characteristics. The main processing and interpretation software features the interactive use of multi GPR sections, displays tomographic maps and operates in a CAD environment. A relational data base manages the collected data. The software can generate a final CAD cartographic map in 3D containing both surface evidence and GPR interpretation. RIS MF is also able to acquire cross-polar data; a dedicated software uses this data on the post-processing unit to provide information on soil type. Finally, the cartographic map is automatically generated, containing all the results in cross section and planar view.

 RIS MF Hi-Mod
  • Deep and shallow antennas in one compact box: Two antennas in the same box, with the option of choosing 200 MHz & 600MHz or 400 MHz & 900MHz, help the operator to locate pipes and cables by providing the proper frequency for a specific search parameter. It provides a real-time display of deep and shallow antennas on the same screen.
  • Modular: Antenna boxes can be quickly added in "chain connection" while in the field (no tools required) with up to 8 in operation simultaneously. As a result, the system is able to work in any available space.
  • 3D Radar Tomography: Multi-frequency data fusion and a consolidated procedure to collect the data enable accurate 3D images of the subsurface to be achieved, helping the operator to distinguish individual anomalies and buried targets.
  • Professional utility mapping capability: The result can be exported in several formats including GIS and CAD (AutoCAD or MicroStation) for a professional survey.
  • Flexible: Powered by the IDS Multi-channel Control unit, the system can be used to drive every IDS antenna.

Post Processing Software

The GRED HD post processing software family is modular. Every module includes the capability of the software listed above.

GRED HD Basic - Recommended for generic basic post processing analysis and road pavement evaluation

GRED HD is an easy to use post processing software able to post process the data acquired with the IDS K2 FastWave. The software offers general tools and features and can be used for several applications from geology and archaeology to underground utility detection.

This software is equipped with basic features and is recommended for users that have to analyze data in the office and want to maximize their capability of interpretation. With this software the user will be able to process in 2D the radargram acquired in the field.

The software is able to show the B-Scan (radargram) acquired and to apply several types of filters (background removal, gain, mitigation time domain, etc.) to obtain an easier to interpret B-Scan. It is also possible to set filter macros for iterative filtering of the data. Anomalies as well as pipes can be marked directly on the interface. GRED HD Basic is also able to do semi-automatic layering reconstruction and insert core.

GRED HD 3D - An Advanced GPR Processing and Imaging Software

Recommended for pipe and utility mapping and 3D analysis of the subsurface

GRED HD 3D is an advanced post processing software for 3D and tomographic rendering of the acquired data.

The software is able to present a 3-dimensional view of the subsurface, with a complete set of options for navigate within it, cutting it and marking anomalies. The software is also able to export 2D plan-view slices of the subsurface from which the operator can best interpret anomalies and pipes.

The pipes and cables detected can be marked with a dedicated tool where the operator can specify a color for each pipe, the depth of it and an estimate of the dimensions. The marked pipes can then be visible in the 3D view, the 2D tomography slice and the traditional radargram.

The software is also able to show multiple radargrams simultaneously to enhance the capability of the interpretation.

GRED HD 3D CAD

GRED HD 3D CAD is specifically designed to offer an integrated framework for CAD and GIS, combining the characteristics of industrial productivity with high levels of reliability. It also offers unique features such as the creation and display of 2D and 3D tomograms in just a few minutes after the basic filtering of the raw data and the direct export of structures and objects of any generic shape to CAD or GIS maps.

The software is fully compatible with any GPS or positioning data in order to obtain automatically geo-referenced data plots.

Key features include:

  • Real-time display of trajectories using GPS or Total Station.
  • 2D and 3D tomography for an immediate visualization and detection of anomalies.
  • Automated transfer to CAD/GIS: the identified target can be automatically transferred to CAD or GIS maps for professional SUE / utility mapping.
  • Geolocated data information and visualization
