The latest version of GlobalMapper Improves LiDAR options. Here it is from the press release. It upgrades point filtering, metadata and compresses data smaller than the .LAS format.
Global Mapper 14.1 provides a dramatic increase in LiDAR processing and display speed and the ability to view and process point files in the hundreds of millions range. This is beneficial for previewing the data before creating a gridded surface model and includes several options for filtering the data during import and for rendering the point cloud to reflect return type or intensity. Improved metadata access provides a detailed statistical breakdown of the point cloud and customizable point size improves on-screen display. Global Mapper Package (.GMP) files are now able to store LiDAR point clouds in a special compressed format, much smaller than uncompressed LAS data and on par with the best compression available today. This allows LiDAR data to be efficiently archived or shared with other Global Mapper users.
