Our flagship product is the LAStools software suite, which is an easy download (~80 MB) and is available for licensing (see pricing). It is a collection of highly efficient, batch-scriptable, multicore command line tools. We have tools to classify, tile, convert, filter, raster, triangulate, contour, clip, and polygonize LiDAR data (just a few functions). All the tools can also be run via a native GUI and are available as LiDAR processing toolboxes for ArcGIS versions 9.3, up for QGIS versions 1.8 and up, and ERDAS IMAGINE versions 14.0 and up.

LAStools are the fastest and most memory-efficient solution for batch-scripted multicore LiDAR processing and can turn billions of LiDAR points into valuable products at blazing speeds and with low memory requirements. For seamless processing of large amounts of LiDAR, we further offer the BLAST extension of LAStools.
