New LASliberator “frees” LiDAR from Closed Format

PRESS RELEASE (for immediate release)
April 20, 2015
rapidlasso GmbH, Gilching, Germany

The latest product by rapidlasso GmbH – creators of LAStools and LASzip – is an open source tool aiming to liberate LiDAR points locked-up in proprietary “Optimized LAS” – a highly controversial, closed LiDAR format. The new LASliberator can be downloaded here. It comes as both, a simple command line tool for scripting and with an easy-to-use graphical interface.

The GUI version of the LASliberaor has a simple and easy-to-use interface.

The GUI of the “LASliberator” has a simple, easy-to-use interface.

The LASliberator reads LiDAR points from closed “Optimized LAS” files that use the “.zlas” extension and converts them to open ASPRS LAS files that use the “.las” extension. Alternatively, the points can be stored to compressed LAZ files – using the open source LASzip compressor – that use the “.laz” extension. In addition, the tool creates tiny spatial indexing files that use the “.lax” extension. These can then be exploited for accelerated area-of-interest queries via open source LASindex when using LAStools or the latest version of the LASzip DLL.

Note that the LASliberator cannot entirely be open source as it depends on a particular proprietry library. The closed nature of the “Optimized LAS” format does not allow for a full open source implementation. It is therefore not possible to port the LASliberator to other operating systems or into other programming languages.

Selecing open in the GUI pops up a file selection dialogue allowing the user to find the file that is to be set free.

The user can select a file to liberate by pressing “open” in the GUI.

The new LASliberator comes on the heels of an outcry in the community over the LiDAR format fragmentation “Optimized LAS” is creating. It provides an immediate solution to go from closed zLAS to open LAZ for people whose LiDAR got stuck in yet-another-proprietary-format.
