Retrieving LiDAR data from LAS files using LibLAS.

Posted by – Sunday 2012-02-05

LAS is the de facto standard file format used for interchaging LiDAR data, “a public file format for the interchange of 3-dimensional point cloud data data between data users” [note 1] [1]. It has been created by the ASPRS (American Society for Photogrammetry and Remote Sensing) and the current format version is 1.4 [note 2] [2].

In this post we will see how to retrieve the (x, y, z) data from a LAS file using the LibLAS tools in a Ubuntu Linux environment.

1. Installing LibLAS

In a Ubuntu Linux computer, using the command apt-get to install the package liblas-bin will install the LibLAS utilities [3, 4] plus the required libraries:

$ sudo apt-get install liblas-bin

LibLAS can also be compiled from the source code. On the other hand, MS Windows users can install LibLAS and its associated utilities using OSGeo4w [5].
