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 trajectory to accurate terrestrial scans […]
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 info@rapidlasso.de before using lasdistance commercially. Please
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 is that their rotation matrix
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 GPS-time stamp and return number.
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 classification 2 or 3. The
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 file for more information.
Compares rasters in ASC, BIL, TIF, IMG and RasterLAZ format andreports differences. See README file for more information.
reads LIDAR data in the LAS format and computes statistics that tell us whether the precision „advertised“ in the header is really in the data. Often I find that the scaling factors of a LAS/LAZ file is miss-leading because they make it appear as if there was much more precision than there really is. To
