Finds sufficiently planar patches of LAS/LAZ points fulfilling a number of user-defineable criteria that are output as simple polygons to SHP or RIEGL’s PEF format. The tool was originally designed for generating tie planes to match the point clouds of a mobile scan that suffer from errors in the GPS
This is a tool for bare-earth extraction: it classifies LIDAR points into ground points (class = 2) and non-ground points(class = 1). This is a totally redesigned version of lasground that handles complicated terrain much better where there are steep mountains nearby urban areas with many buildings. You can use
This tool classifies, flags, or removes LiDAR points based on their approximate xy distance from polygonal segments. This distance is calculated on a grid with a spacing of 0.5 meters by default. With ‘-step_xy 1.0’ the granularity of this grid can be adjusted up or down. Please license from email@example.com
compares the LIDAR data of two LAS/LAZ/ASCII files and reports whether they are identical or whether they are different. See README file for more information.
Transforms LiDAR from one horizontal datum to another using either a NTv2 grid or a seven parameter helmert transform. Note that there are two ways of specifying the rotational part of the Helmert transform. The Position Vector Transformation (PVR) convention and the Coordinate Frame Rotation (CFR) convention.The difference between them
This tool copies selected attributes from LiDAR points from a source to a target LAS/LAZ file using the GPS-time stamp and the return number as a reference. By default the selected attributes of the source points are copied to all target points if the two share the exact samecombination of
reads LIDAR data in LAS/LAZ/ASCII format and creates a TIN. It is possible to triangulate only certain points like only first returns (-first_only) or only last returns (-last_only). One can also only triangulate only points that have a particularclassification. The option (-keep_class 2 3) will triangulate only the points of
converts LIDAR from LAS/LAZ/ASCII to ESRI’s Shapefile format by grouping consecutive points into MultiPointZ records. The default size is 1024. It can be changed with ‘-record 2048’. If you want to use PointZ records instead you need to add ‘-single_points’ to the command line. See README file for more information.
Compresses and uncompresses raster data from ASC, BIL, TIF, IMG format to the compressed RasterLAZ format. The expected inputs are rasters containing elevation data such as DTM, DSM, or CHM rasters, or GEOID difference grids, or forestry metrics. These values will be compressed into the z coordinate of RasterLAZ. See README
Compares rasters in ASC, BIL, TIF, IMG and RasterLAZ format andreports differences. See README file for more information.
