Interpretation Module

The Interpretation Module works within LineView:

  • Users can interactively add localized targets, layers, labels and identifiers on the GPR lines
  • All interpretations are stored in the .gpz database
  • Point interpretations appear in the MapView window
  • All spatial information is integrated with records stored within the database

Types of Interpretations:

  • Points – Defines hyperbolas and point targets
  • Polylines – Defines continuous or discontinuous boundaries
  • Boxes – Defines a rectangular box around an area of interest
  • Annotations – Text pointing to a specific location in the data image

Editing tools allow all interpretations to be inserted, deleted or moved. Each interpretation has automatic or user-defined properties like color, style, markers and marker size which make it easy to distinguish between them. Often-used interpretations can become “templates” available for new projects. For example, if your interpretation is a red-colored polyline called “Bottom of Concrete” and you want to use it with other projects, make it a template.

Interpretations can exported in different ways:

1) As an Project Report: CSV (Comma Separated Values) files with the quantitative values for the interpretations, i.e. positions along the GPR line, GPS (if available), depth, time, signal amplitude

SliceView Module

The SliceView module creates GPR depth slice maps quickly and easily. Using the systematic grid data acquisition process common to pulseEKKO, Noggin, LMX or Conquest systems, images at multiple depths are generated in minutes.

SliceView features:

  • Display multiple cross-sections and depth slices
  • Hyperbola-fitting tool for velocity estimates
  • On-screen tape measure
  • User-defined depth slice thickness
  • Automatic grid creation based on GFP files created during acquisition
  • Incorporate GPS coordinates on depth slice outputs
  • Legends for depth slice and cross-section information
  • Display multiple grids simultaneously
  • Simple switching between metric and imperial units
  • Adjustable resolution to optimize processing
  • Support for large grids
  • Merging of bi-directional and dual polarization data
  • Superimpose depth slices over Google Earth ground images(grids only)

SliceView provides examination of multiple depth slices, selection and viewing of cross-sections, choice of processing streams and optimization of gain, image contrast, sensitivity and color.

SliceView 3D Visualization

SliceView supports 3D volume data in HDF and CSV file formats for easy use in third-party 3D visualization programs such as Voxler. Voxler provides many display options including volumes, variable-opacity views, isosurfaces and orthogonal or oblique slices, rotation and different colourmaps. Images are saved as graphic image files (BMP, JPG).

Processing Module

The Processing Module provides a range of common GPR signal processing and analysis tools:

  • Migration, time and spatial filtering and attribute creation
  • Frequently-used processing recipes can be built, stored and re-used
  • Processing can be applied to a single GPR line, a selected group or all GPR lines with ease
  • Processing can be undone with a single click

Specialized Reporting Modules

Bridge Deck Condition Report Module

The Bridge Deck Condition Report Module requires the Interpretation Module. The Bridge Deck Condition Report outputs, in a report format, a GPR Response Amplitude map image and the statistical summary of all the picked rebar in a reinforced concrete structure. The report includes several fields for the GPR operator to fill in including the survey location, number of lanes and the GPR system used.

Survey Summary

Display key bridge and project information based on operator filled fields

Bridge Deck Condition Report features:

Response Amplitude Maps

Signal attenuation map images are generated by interpolating rebar amplitude values into the gaps between GPR lines. Two types of Response Amplitude displays are available:

  • Raw Amplitude Maps – yields GPR signal strength in millivolts (mV)
  • Signal Attenuation Maps – presents GPR signal strength in decibels (dB). This is often referred to as a Deterioration Index map. The ‘dB‘ map uses an enhanced version of the processing outlined in ASTM 6087 (Standard Test Method for Evaluating Asphalt-Covered Concrete Bridge Decks Using Ground Penetrating Radar).

Rebar Response Amplitude Map.

Rebar Response Amplitude Map. Higher values (red) indicate areas of higher attenuation which may indicate bridge deck deterioration due to saline intrusion and rebar corrosion.

Amplitude image options:

  • User-selectable color palette
  • Amplitude range plotted can be set to
    • Automatic – full range
    • Manual – user sets the range to emphasize high or low amplitude (or attenuation) areas or, to compare maps from more than one bridge deck using the same range
  • Export Response Amplitude map image to png., bmp., or jpg. graphic file formats

Statistical Summary

The software automatically generates statistics on the reinforcement depth and spacing, including:

  • minimum, maximum and average amplitude
  • minimum, maximum and average rebar depth
  • minimum, maximum and average rebar spacing

Export data in CSV format:

Export the calculated amplitude values (in mV or dB) to a .csv file. This allows the user to import the data into third-party software for image generation and further analysis.

This powerful analysis can be used for bridge decks, parking decks, and even walls and floors of concrete buildings.

Pavement Structure Report Module

The optional Pavement Structure Report requires the Interpretation Module. The Pavement Structure Report module outputs in a report format the pavement thickness charts of all the layers added to the GPR Lines. The report includes several fields for the GPR operator to fill in including the road name, number of lanes and the GPR system used.

Pavement Structure Report includes:

Pavement Structure charts for each GPR line. Charts that display the thicknesses of the asphalt and granular layers. These charts are interactive. Place the mouse cursor anywhere on the chart to display the position along the line and depth of each layer at that position. Pavement structure chart displaying the thicknesses of the asphalt and granular layers over a 470 meter length of road. Blank areas indicate areas where confident picks could not be made.

While the EKKO_Project Pavement Structure Report is designed for typical road survey analysis, the “pavement structure” can take many forms. This analysis and reporting tool can also be applied to any layered structures such as rail beds, runways, water depth and bathymetry, snow and ice thickness, and layered geology.
