Detailed list of fixes includes:

  • #120 – support ‘comma’ as a separator in las2txt
  • #121 – las2txt and txt2las don’t work with the Point Source ID
  • #122 – las2las does not eliminate requested classifications
  • #124 – some files have pad bytes when they shouldn’t
  • #127 – Scan flags is order sensitive
  • #129 – Version.rc doesn’t make the release
  • #132 – Require libgeotiff when GDAL is requested
  • #133 – FreeBSD endian.hpp
  • #134 – GDAL transform translates the points incorrectly when there is a scale or translation on the points
  • #136 – Problem overwritting Reader’s dataoffset due to VLR
  • #139 – txt2las is not setting the point source id correctly for values > 255
  • #140 – liblas 1.2 linking problems due to –with-hide-internals gdal option
  • #141 – lasinfo in not reporting info about point source id
  • #143 – libLAS 1.2 requires GDAL 1.7 (unreleased)
  • #144 – Apps should take in filenames without -i argument
  • #145 – Memory leak from LASWriter / lasspatialreference assignment operator=
  • #148 – No prototype in core.py for LASPoint_Destroy

On behalf of the libLAS team, thanks to all who provided bug reports and patches!

Before delivering next major release of libLAS, there is one big issue that must be fixed. It is problem with large files under Windows 32-bit operating system – ticket #147. Volunteers are welcome to take care of it :-)

I would also like to see completed build configuration based on CMake – ticket #52. It is already usable on Unix (GCC) and Windows (Visual C++), so testers are welcome to give it a try and give us feedback.

libLAS - ASPRS LiDAR data translation toolset Hobu proposed motion to migrate libLAS source code repository from Subversion to Mercurial. The motion has been approved and Hobu completed the mgration.

In order to check out libLAS source code from the new repository, issue the clone command:

hg clone http://hg.liblas.org/

The libLAS Trac has been re-configured to make the new repository browsable. Alternative Web-based interface is available at http://hg.liblas.org/.

FOSS4G 2008, I can’t make it

…school, job, trips, move, army, school, move, new job…lots of things have been happening in my life with speed of light, so I’ve had to change most of my plans, especially those about traveling. And, I can’t make it to attend the FOSS4G 2008 conference.

Nevertheless, I’m still listed next to two positions of the conference program and that’s correct. I planned to help Frank Warmerdam during the Raster Processing and Preparation with GDAL workshop and to give one presentation – Introduction to ASPRS LAS data processing with libLAS.

Apparently, I won’t be able to assist Frank during the workshop – I’m sorry Frank! and I’m crossing my fingers for you. And, the libLAS presentation will be given by…Frank – crossing my fingers harder :-) Originally, I promised Frank I will provide him with presentation slides and I’ll be a virtual assistant. Actually, I failed even with that :-(

Fortunately, Hobu took over this task and prepared PDF document with a set of fantastic slides. Frank and Howard have really saved my ass and I’d like to send them veeery big thanks!

I regret I can’t come to Cape Town, to experience the fantastic atmosphere, to see hundreds geogeeks together, to have a great time with friends and to drink a little too much beer with Tim. See you guys in Sydney, 2009!
