Various private and public infrastructure projects routinely involve the mapping of geological
structure to determine potential instabilities, assess hazards, and calculate support …

This paper describes experience gained in the application of terrestrial digital
photogrammetry and terrestrial laser scanning for the characterization of the structure of high …

Terrestrial light detection and ranging (LiDAR) can be used for the delineation and
evaluation of geomechanically controlled hazards. The United States Geological Survey [1] …

Rock face diagnosis is a monitoring operation that is used to optimize rock-risk treatment
works in terms of ensuring that safety requirements are met at the lowest cost. Diagnoses …

This paper demonstrates and evaluates 3-dimensional laser scanning (Lidar), in conjunction
with block modelling, as a tool for underground rockmass characterization and stability …

Lidar is a remote sensing technology that uses time-of-flight and line-of-sight to calculate the
accurate locations of physical objects in a known space (the known space is in relation to …

Often when rock discontinuities with complex distributions occur in steep terrain, it is difficult
to rapidly survey and accurately measure their spatial distribution by traditional surveying …

A new methodology is presented for 3-D automated mapping of joints that are exposed
primarily as traces in a rock face as opposed to planar facets. The method identifies 3-D …

This paper presents a methodology for semi-automatic extraction of rock discontinuities from
point clouds on the resulting 3D digital surface models of rock masses acquired by terrestrial …

In this paper, two analytical procedures which are independent from the existence of
empirical data are presented for the calculation of (1) the size distribution of potentially …
