to this, is there a plan to replace liblas with the new Python
alternative (the name escapes me at the moment)? This would further
simplify making robust LiDAR tools available in GRASS</blockquote><div> </div></div><div class="gmail_extra"><div class="gmail_quote">On Sat, Apr 30, 2016 at 12:36 PM, Michael Barton <span dir="ltr"><<a href="mailto:Michael.Barton@asu.edu" target="_blank">Michael.Barton@asu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="word-wrap:break-word">The LiDAR tools I was thinking of is PDAL.

<div>I guess it's C++. </div></div></blockquote><div><br></div><div>Yes,
it's C++ not C or Python and it currently does not have C API, so it might be
even harder to connect in general. The basic functionality newly (since
release 1.2) does not depend on Boost but the new C++ (I think C++11) is
needed. It is important to note that most of the fancy functionality
(like ground detection) is provided through another dependency, PCL
(<a href="http://pointclouds.org/">http://pointclouds.org/</a>), which is a large point cloud processing
library which depends on Boost (if I recall correctly).<br><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="word-wrap:break-word"><div>But it's open source without some of the legal and compiling issues of LAStools.
