COVER
Vertical base surface overlaid on a combined RESON A/S (Slangerup, Denmark) Seabat 7125 multibeam and Terrapoint (Hamilton, Canada) ALMIS-350 lidar 3D point cloud scene showing a quay wall section for an inspection survey for the Port of Quebec, Canada, in June 2011. The color scale’s range is 3 meters. A good condition sheet pile section is visible on the left, a concrete delamination of about 1-meter thickness is in the middle, and an undermining of about 1.5-meter thickness is on the right. The no-data strip is due to a tidal shift between the multibeam and lidar acquisition times. (Photo Credit: CIDCO / Mosaic 3D, Canada)
