This file describes the data used in the paper "High-resolution monitoring of wave transformation in the surf zone using a LiDAR scanner array", published in Coastal Engineering, vol. 128, pp. 37–43. doi: http://dx.doi.org/10.1016/j.coastaleng.2017.07.007 The dataset is composed of 3 .mat files, which were generated with the MATLAB software. Mostly, the data consists of the surface elevation for each of the 116 waves measured by the LiDAR and presented in the paper. Along with this, the data used to produce Figure 6, and the breaking point locations detected by every method (used to produce Figure 7) are also provided. The content of each file is described in the metadata contained in the structure data. This dataset is distributed under the Creative Commons Attribution 4.0 International license.
