min_distance

Estimate the minimum distance between points in a point cloud.

A set of tools to process and calculate
metrics on point clouds derived from terrestrial laser scanning (TLS)
also know as terrestrial LiDAR (Light Detection and Ranging). Its
creation is based on key aspects of the TLS application in forestry
and ecology. Currently, the main routines are based on filtering,
neighboring features of points, voxelization, canopy structure,
and the creation of artificial stands. It is written using
data.table and 'C++' language and in most of the functions it is
possible to use parallel processing to speed-up the routines.
