3DR-Examiner revolutionizes the processing and analysis portion of working with GPR data, through its unique ability to quickly process and navigate large data sets, and by providing an intuitive and user friendly environment for visualization, analysis and reporting. 3DR-Examiner does much more than process and optimize 3D-RADAR GPR data. 3DR-Examiner integrates GPS coordinates, maps/imagery and external annotations, then provides a simple and straight-forward way to visualize the data. Additionally, the tool enables the user to generate output data for final reporting. These capabilities enable 3DR-Examiner to dramatically reduce the time required to process 3D GPR data.

Processing & VisualizationBecause 3DR-Examiner has been designed from the outset to work with large datasets covering many sq. km./miles of area, identification and classification of any anomalies in the subsurface is dramatically simplified. 3DR-Examiner enables the user to view data in one of two modes, called “Overview” or “Explore”. Unique to 3DR-Examiner, Overview shows all the data in the project geo-referenced. This view enables all the data to be displayed and traversed through for an initial review, giving the user the opportunity to quickly identify subsurface areas for further investigations. Presented in full resolution, users can pan, zoom and dive in the data in real-time, with the display updating automatically, without needing to wait for offline rendering or “stitching” of the data. Change the depth and the data changes right away. Click and drag a file to align it with another, and the rendered GPR data moves on screen instantly to show how the data will align. Geo-referenced images can be imported from aerial,

Map overlays, no matter where in the world are provided by 3DR-Examiner accessing an integrated map service, OpenStreet . A graphical editor is supplied for manualoverrides if necessary.

Overview mode also includes a sophisticated tool to draw 3-Dimensional annotations on the data. The annotations can be exported with rendered GPS data to popular formats including AutoCad (DXF), Google Earth, video and geo-referenced images in almost any projection. The data can also be sliced along arbitrary multi-segment lines, to show “virtual trenches” of the data.

State of the art multi-channel 3D GPR systems easily produce datasets topping 10GBytes of data per file. Such data files are difficult to manage and time consuming to process. Designed specifically to handle very large data sets, 3DR-Examiner uses a combination of careful disk and memory management, parallel processing and efficient algorithms to process, visualize and navigate large volumes efficiently. 3DR-Examiner is capable of processing data much faster than it can be collected, allowing users with relatively high-performance but inexpensive PCs to easily handle data sets several tens of gigabytes in size.

Multiple swaths of collected data can be easily stitched together. This can be done either manually by referencing a known location in the data or letting 3DR-Examiner perform

this task using supplied GPS coordinates. If data is collected using a TotalStation or is optimized using Precise Point Positioning, additional corrections may not be necessary.

This feature alone saves several hours of post-collection manipulation by the end user.

The Explore View

Once an area of interest has been identified, the user simply has to double-click on the location to open the Explore view, a classical three-slice view for more detailed investigations. This view slices a file in three directions and allows easy navigation in the file in 3-Dimensions.

Explore view is also the work area for the optional advanced analysis tool supplied in 3DR-Examiner for automatic interface/layer tracing. The high-resolution multi-channel data from the 3D-RADAR system is uniquely suited for interface tracing, and this tool can trace kilometers of layer interfaces in 3-Dimensions with a single click using an advanced spatial layer tracing algorithm. Easy-to-use edit brushes make manual edits and overrides easy when necessary. The end result is visualized on screen as depth profiles and color coded maps. Interfaces can be visualized and geo-referenced in the overview, and can be exported from there along with the GPR data. It can also be exported to other applications in several numerical formats.

Export & Extensibility

3DR-Examiner imagery can be cut and pasted into other applications for reporting. The package also allows data-export into leading third-party analysis and reporting tools such as GPR-Slice, RoadDoctor and others. The export format is fully documented, allowing data to be exported into end-user developed analysis software. With assistance from 3D-RADAR’s technical team, users can develop and integrate specific processing tasks in order to implement custom processing steps and integrate them into the data processing tool chain. These integrate into the 3DR-Examiner data model. Output from these processing tasks can be stored in the project file, visualized in the overview and be part of the exported data.
