RADAN Software

RADAN also features simplified 3D viewing. The Interactive 3D module provides enhanced 3D viewing options in a single dialog box. Users can stretch, shrink or zoom in on files as desired for customized presentation results. The Interactive 3D module also allows the entire data cube to be “sliced and diced” along various x, y, and z planes. This allows the user to easily interpret complex areas and to make sense of the data. With Interactive 3D’s simple, intuitive click-and-drag interface, viewing multiple slices and rotating the data for a better view has never been easier.

The Interactive 3D module also affords users the ability to show multiple interactive views of 2D and 3D data simultaneously and to create shapes (pipes, drums, lines, etc.) in the GPR data, which can then be exported for integration with CAD drawings. This way, the data can be presented to the client in a familiar, easy to understand format. All of these 3D options provide users with unparalleled data interpretation and presentation capabilities that allow them to showcase their expertise, make better interpretations and get more jobs.

The Structure Identification module is the heart of GSSI’s StructureScan systems. This powerful tool allows for easy creation of planview slices to aid in interpretation of StructureScan data files.

The versatility of this module allows for a broad range of civil/structural applications, including structures with different types of reinforcement.

• Semi-automatic mapping of rebar locations and depths on simple concrete structures
• Interactive location mapping of conduits within concrete structures
• Semi-automatic mapping of deterioration zones within concrete structures

Capable of identifying rebar and calculating concrete cover over rebar on new deck structures; performs deterioration-mapping using GSSI's patented data analysis method and is designed so that post-processing and analysis are streamlined specifically for bridge deck data. Perfect software for large bridge deck structures with typical two-layer orthogonal grid reinforcement patterns.

RADAN's Road Structure Assessment module is designed for use with horn (air-launched) antennas. This module uses a signal calibration technique (where a metal plate reflection amplitude is compared, scan by scan, to raw data obtained from pavement analysis surveys) that measures significant layer interface amplitudes from the pavement data and calculates the propagation velocity of the GPR signal through the pavement layer media.

This is significant because it allows pavement thickness, base thickness and other pavement structure properties to be calculated without ground-truth (core) data.

This software module includes automatic and interactive layer interpretation, automatic and interactive pavement thickness (but user CAN specify core data, if desired), and provides output of signal and position information to an ASCII database for roadway condition assessment.

BallastVue is an optional module in RADAN version 6.5 that automatically processes 2 GHz horn antenna data obtained on the shoulders of railroad tracks. The processed data can be viewed in RADAN, saved as an ASCII text file, or exported in KML format for viewing in Google Earth™.
