An Iterative Coarse-to-Fine Sub-Sampling Method for Density Reduction of Terrain Point Clouds
Point clouds obtained from laser scanning techniques are now a standard type of spatial data for characterising terrain surfaces. Some have been shared as open data for free access. A problem with the use of these free point cloud data is that the data density may be more than necessary for a given...
