The LAS header.

Fields

file_source_id: Option<u16>

The file source ID.

This does not exist for LAS 1.0 files.

global_encoding: Option<GlobalEncoding>

The global encoding.

This does not exist for LAS 1.1 and 1.0 files.

project_id: [u8; 16]

The project id number.

version: Version

The LAS version.

system_id: [u8; 32]

The system identifier.

generating_software: [u8; 32]

The generating software.

file_creation_date: Date<UTC>

The day of file creation.

point_format: Format

The point format.

extra_bytes: u16

The number of extra bytes in the point beyond the standard.

point_count: u32

The number of points.

This value is taken from the header and is notoriously inaccurate.

point_count_by_return: [u32; 5]

The number of points by return count.

scale: Triple<f64>

The scaling that is applied to points as they are read.

offset: Triple<f64>

The offset of the points, in each dimension.

bounds: Bounds<f64>

The three-dimensional bounds, from the header.

vlrs: Vec<Vlr>

Variable length records.

padding: u32

Arbitrary byte padding between the header + VLRs and the points.

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Header

fn default() -> Header

Returns the "default value" for a type.
