Laser scan of cliff face showing previous cross section lines
merged with the point cloud. The cliff face was meshed and then
the site revisited following a rock fall. By comparing the two
meshes, the volume of material that had been eroded was calculated.
The white lines show cross sections recorded years before, now
superimposed on the 'point cloud' to show erosion over time.
experience with mapping coastal areas includes combining
terrestrial laser scan data with airborne LiDAR to map coastal
area at Lyme Regis. Deliverables
included highly accurate volume computations. Beach profiles,
contour maps and topographic details.
Additional promotional products included animation flythroughs
and LiDAR pointcloud.
have also laser scanned failing cliffs, laser scanning provides
a fast and safe method by which the rock face can be measured.
Block sizes can be established and cross sections and contour
models can be produced for use in rock fall modelling applications.
Complex meshing allows for fracture mapping and fracture orientation
to be established.
