I. Introduction

This idea is very simple, first get the closest point of each point in the point cloud, then calculate the distance from the point to its closest point, accumulate this distance, and finally divide by the number of points to get the average point cloudspacing.Although it is very simple, this function is very practical. For example, the use of canopy analysis (VCP) to extract the leaf area index will use the average point spacing of the point cloud.
