libLAS 1.6.0 released

Howard Butler
All,

I would like to announce the release of libLAS 1.6.0 [1]. libLAS is a BSD-licensed library for working with the ASPRS LAS LiDAR format [2].  libLAS uses some of the same technologies that PCL does including Boost and CMake, and it focuses on providing read/write capability for this format along with some other tools that focus more on tasks that an airborne LiDAR user would be interested in.  I thought there may be a little interest in it for PCL users, if only as a part of PCL io.  Highlights include the ability to read/write LAS data, compress data via LASzip [3], and output summary information for the venerable LAS format.

Thanks,

Howard

That sounds fantastic! It would be great to integrate it with PCL and have us exchange data in LAS format! I have to
admit that I wasn't aware of LAS, so I need to do a bit of reading to understand it better.

We have two options here:
  * code a wrapper and integrate it with pcl_io for the 1.0 roadmap (see http://pcl.ros.org/Roadmap)
  * wait until 1.0 is out, and plan this better for 2.0. We are going to do a bit of an overhaul with one big change
being that we're getting PCL outside of ROS completely, and building a ROS wrapper for it instead, rather than the other
way around. This means that we will be able to do cmake checks on the PCL side to see if a certain library is already
installed on the system, and enable/disable parts of PCL based on that.


Cheers,
Radu.

A libLAS user has provided some CMake to find libLAS on the system that can be reused [1].

http://liblas.org/tutorial/cpp.html has some basic tutorial information, and feel free to join the liblas-devel mailing list http://liblas.org/community.html if you have any questions.  I'm also on #liblas on freenode most days as well.

Thanks,

Howard

Sounds good.

Would it make sense to build support for it in 1.0? We're days away from its release, but if we can come up with some
tutorial/code examples/unit tests quickly, we could easily add it.

What are your thoughts on this?


Cheers,
Radu.

I don't have any time to implement as I am preparing for ILMF, but I can help with questions is someone has the time to do a rush job.  I guess I'd categorize it as a nice to have rather than need to have, even for a 1.0 release that might not see a new release for a number of months.
