abstract = {This paper presents a review of the data acquisition
procedures of geotechnical parameters for rock slope
stability assessment and the proposal of some new
improvements. For this purpose, a piece of research based
on the slope mass rating classification system using closerange
terrestrial digital photogrammetry (CR-TDP) has led
to improvements in quality and timing of discontinuity data
acquisition, and analyzes the suitability of each one of the
parameters when applied to weak foliated rocks. TDP
allows rapid 3D image acquisition of a rock slope, which
can be analyzed using software to determine the geometrical
parameters that affect stability. A fast procedure to
perform the photogrammetric, non-contact survey in order
to obtain the 3D images is shown in this paper. Being a
rapid and single-person task, this procedure provides
enough precision to be applied to weak foliated rock slopes
with non-well-defined geometry. Furthermore, the study
has focused on highly foliated rock outcrops, in which high
resolution in the 3D images is very desirable. This research
was applied to mountain road cuts, in which the use of TDP
with a very close range was necessary. Through an application
on weak rocks in the Alpujarras (Andalusia, Spain),
this work analyzes the bias when applying TDP to materials
such as these, under progressive weathering processes.},
