filter_flightlines: Filter flight lines based on the number of points in each

In mbedward/CERMBlidar: A collection of functions to process aerial LIDAR data

Filter flight lines based on the number of points in each

Description

This function takes an input LAS tile and returns a copy from which any flight lines with less than a specified minimum number of points have been removed. It is used by prepare_tile but can also be called directly. If points are dropped, the header of the returned LAS object is updated.

Usage

filter_flightlines(las, min.points = 1000)

Arguments

las	A LAS object, e.g. imported using prepare_tile.
min.points	The minimum number of points in a flight line for it to be retained. The default value (1e3) is intended to exclude flight lines that only appear at the margins of the tile.

Value

A (possibly) modified copy of the input tile with any sparse flight lines removed.
