LizardTech Awarded Lidar Patent for Point Cloud Compression

LizardTech, a provider of software solutions for managing and distributing geospatial content, has been awarded a USA patent for the compression of Lidar point clouds. The patented technology provides lossless compression of point clouds captured by airborne Lidar sensors or terrestrial laser scanners for easy and cost-effective processing, storage and transmission of data sets.

“Lidar systems capture terabytes of data that can be difficult to exploit due to the difficulty processing such massive files,” said John Hayes, LizardTech Senior Engineer. “Our Lidar compression technique allows users to maximize their return on investment in point cloud data collection.”

LizardTech developed the Lidar compression technology by leveraging the wavelet transformation algorithms used to compress satellite and aerial image data sets into MrSID formats. The point cloud compression technique was first released as a stand-alone LizardTech product called Lidar Compressor and then integrated into GeoExpress.

GeoExpress is LizardTech’s flagship software product originally created to enable geospatial professionals to manipulate digital satellite/aerial images and compress them to industry-standard MrSID or JPEG2000 files. The addition of Lidar handling gave GeoExpress the ability to natively compress Lidar data to MrSID and LAZ formats with no loss of data content, saving up to 75% on storage and time in processing files.

The Lidar compression algorithms can be licensed via the LizardTech SDK to incorporate the technology into third-party geospatial software solutions. Already, LizardTech is seeing interest in this technology from hardware sensor developers who want to place data compression capabilities at the source of collection.
