Comments on: LizardTech Adds LiDAR Compressor http://www.vector1media.com/spatialsustain/lizardtech-adds-lidar-compressor.html Promoting Spatial Design for a Sustainable Tomorrow Wed, 08 Feb 2012 13:39:33 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Martin Isenburg http://www.vector1media.com/spatialsustain/lizardtech-adds-lidar-compressor.html/comment-page-1#comment-57761 Martin Isenburg Sun, 09 Oct 2011 15:19:52 +0000 http://vector1media.com/spatialsustain/?p=3406#comment-57761 The free LASzip (http://laszip.org) compressor is now in version 2.0.2 allowing random access decompression which is a major improvement over version 1.0. It already has native support in FME 2012, TopoDOT, LAStools, and more vendors will be adding it in their next releases. The largest collection of LAZ content is provided by the DNR Minnesota. You will soon find LIDAR for the entire state online as compressed LAS.
