ASPRS LIDAR Data Exchange Format (LAS) Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The American Society Photogrammetry and Remote Sensing (ASPRS) LIDAR (LAS) Reader allows FME to read LIDAR (data exchange format standard) LAS specifications.

Overview

The LAS file is intended to contain LIDAR point records. The data will generally be put into this format from software (provided by LIDAR hardware vendors) which combines GPS, IMU, and laser pulse range data to produce X, Y, and Z point data. The intention of the data format is to provide an open format that allows different LIDAR hardware and software tools to output data in a common format.

FME supports LAS versions 1.0, 1.1, 1.2, 1.3, and 1.4.

Limited support for Esri LAS Datasets is available when ArcGIS is present. A LAS Dataset is, in its simplest form, a collection of LAS files.

The format contains binary data consisting of a header block, Variable Length Records (VLRs), and point data.

Reading and writing of arbitrary VLRs is not currently supported; only defined georeferencing information VLRs are supported.

Workbench Reader Dataset

The value for the Reader Dataset is the LAS file to be read.

Workbench Writer Dataset

The value for the Writer Dataset is the path of the output directory where the data will be written.
