Chalk Cliffs Channel Surveys derived from Structure-from-Motion
Description
This data release contains two point clouds derived from structure-from-motion photogrammetry. The first survey was conducted on 10 September 2015 and the second survey was conducted on 1 June 2016. Each survey was designed to capture a 35-meter channel reach using digital photos (1187 photos were taken in the first survey and 1085 photos were taken in the second survey). Twenty-five bolts were drilled into the bedrock channel to serve as ground control points. Agisoft photoscan was used to construct point clouds from the digital photos, and then sub-sampled the point clouds to a 1 cm spacing. The two subsampled point clouds are provided here in a las format.
