Remote Characterization of Rock Exposures Using Terrestrial LiDAR
Use of remote sensing methods such as photogrammetry and digital image analysis in rock engineering studies are known to improve productivity and worker safety. This paper presents the use of terrestrial Light Detection And Ranging (tLiDAR) for measuring fracture and bedding plane orientations. Reflected laser pulses are used to acquire closely spaced data points over a surface yielding a three-dimensional digital point cloud. Benefits include ease of operation, digital storage and extraction of site data, ability to gather data in inaccessible areas and the ability to image in any lighting condition. Drawbacks include high initial equipment cost, large data file size and limited availability of analysis software. Plane orientations measured with a field compass at road exposures and within a rock tunnel are compared with orientations measured using the point cloud visualization program gVT. Comparisons between these measurements indicate that tLiDAR gives reliable information, even in areas inaccessible to personnel.
