<br><font size=2 face="sans-serif">Yes!!!! Thank you Markus! Since
you are using liblas 1.6.1 , I assume that this command can read the losslessly
compressed .laz format?</font>
<br>
<br><font size=2 face="sans-serif"> Will try soon.</font>

<br><tt><font size=2>Hi all,<br>
<br>
GRASS 7 has a new module v.in.lidar for importing LiDAR LAS files<br>
(*.las or *.laz). The LAS file format is commonly used for storing<br>
LiDAR point clouds, but is unfortunately not supported by OGR.<br>
v.in.lidar uses the libLAS library [0] and is only compiled if the<br>
libLAS library is present.<br>
<br>
I chose to use the library instead of writing a custom LAS reading<br>
interface because the current LAS library version 1.6.1 is stable,<br>
supports LAS file versions 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, each of<br>
which can store LiDAR points in up to 5 different point formats. The<br>
user and the interface do not need to know the file version and point<br>
format of a given file, all that is conveniently handled by the libLAS<br>
library in the background. The library has Large File Support (LFS)<br>
and is well tested on different platforms, also with different<br>
endian-ness. This functionality is not that easy to replicate.<br>
<br>
You will need to get the libLAS library and configure GRASS 7 with<br>
--with-liblas in order to have the module available. Please test!<br>
