Properties

Extension — Preferred file extension

"las" (default) | "laz"

Preferred file extension, specified as "las" or "laz".

Data Types: char | string

LasVersion — LAS version

"1.2" (default) | "1.0" | "1.1" | "1.3" | "1.4"

LAS version, specified as "1.0", "1.1", "1.2", "1.3", or "1.4".

Data Types: string | char

XYZScale — Scale of XYZ-coordinates

[0.01 0.01 0.01] (default) | three-element real-valued row vector

Since R2024b

Scale of the XYZ-coordinates, specified as a three-element real-valued row vector of the form [Xscale Yscale Zscale].

Data Types: double

XYZOffset — Offset of XYZ-coordinates

[0 0 0] (default) | three-element real-valued row vector

Since R2024b

Offset of the XYZ-coordinates, specified as a three-element real-valued row vector of the form [Xoffset Yoffset Zoffset].

Data Types: double

PointFormat — Point data record format ID

8 (default) | 0 | 1 | 2 | 3 | 6 | 7

Since R2024b

Point data record format ID, specified as 0, 1, 2, 3, 6, 7, or 8. This table shows the supported point data record formats for different LAS or LAZ file versions.

LAS or LAZ Version	Supported Point Data Record Formats
1.0	Point data record formats 0 and 1
1.1	Point data record formats 0 and 1
1.2	Point data record formats 0 to 3
1.3	Point data record formats 0 to 3
1.4	Point data record formats 0 to 3 and 6 to 8

Note

The point data record format in LAS files ranges from 0 — 11. But the LAS object supports 0, 1, 2, 3, 6, 7, or 8 formats only.
