The BLAST extension of LAStools utilizes unique “streaming TIN” technology to seamlessly triangulate billions of points for subsequent rasterization into a DEM with blast2dem or extraction of elevation contours with blast2iso. The BLAST extension is available for stand-alone licensing as well as a discounted add-on to the LAStools software suite (see pricing).
The BLAST extension are two highly efficient, batch-scriptable, multicore command line tools. They can also be run via a their native GUI or through the LiDAR processing toolboxes for ArcGIS versions 9.3, 10.0, 10.1, 10.2, or 10.3, QGIS versions 1.8, 2.0, 2.2, 2.4, 2.6, 2.8 or 2.10 and for ERDAS IMAGINE versions 14.0 and 15.1.
The BLAST extension of LAStools is the fastest and most memory efficient solution to seamlessly process billions of LiDAR points into DTMs, DSMs, CHMs, or elevation contours.
