Ground-Penetrating Radar (GPR) Interactive Data Language (IDL) Software ToolsEntry ID: GPR_IDL_Tools
Abstract: Software tools for opening, viewing, filtering, and analyzing Mala Geoscience RAMAC ground-penetrating radar (GPR) data. These tools are programmed using ITT Visual Information Solutions (ITT VIS) (formerly Research Systems, Inc. (RSI)) Interactive Data Language (IDL) for use within IDL or ITT VIS Environment for Visualizing Images (ENVI) software.
Preprocessing of GPR data is necessary to ... produce quality images with clearly-visible reflection horizons. Mala Geoscience "GroundVision" software, used to acquire and display GPR data from the RAMAC instrument, has filtering capabilities that can dramatically improve the appearance of data when properly applied. Unfortunately, however, these filters are for display purposes only and cannot be permanently applied to the data or saved to a new output file, preventing any post-processing on the filtered data such as digitizing reflection horizons in other image-processing applications. To circumvent this limitation, we have simulated the GroundVision filters based on their description in the manual into a programming environment that allows the user to save the results for subsequent processing and data analysis.
