| Description | Georadar survey might significantly contribute to the understanding of sub-surface processes at areas of interest in geoscience and related technical fields. It is usually necessary to cover the construction area with a detailed grid of measurements (within the first 100 survey lines) to identify the critical anomaly or damaged construction part. Evaluation and presentation of this huge collection of data by the author is difficult to explain to the client due to the complexity of the situation. Graphical visualization of the georadar results in 3D combined with technical maps of the area could reduce the complexity of the output and be beneficial for all users. This graphical presentation can’t be obtained using specialized GPR processing software alone. Program Voxler v2 (Golden Software, Inc.) allows for manipulation and visual presentation of GPR pre-process data. Visualization itself is created for (i) the original source data (scatter plot), (ii) for their 3D interpolation (volume rendering, etc.), (iii) for the classic raster images (radargram, time slices) including the visualization of georeferenced images in horizontal layout or their angular transformation up to the vertical profile layout. Real field data is used to document the advantages of the 3D graphical presentation for identification of sub-surface anomalies. |
