It hasīeen tested with large datasets (see below for memory managementĪvailable statistics for populating the output raster map are:Ĭoefficient of variance of points in cell R.in.lidar is designed for processing massive point cloudĭatasets, for example raw LiDAR or sidescan sonar swath data. LAS dataset itself along with the desired raster resolution. LiDAR point cloud to be imported, then adjust the current region extentĪnd resolution accordingly, and only then proceed with the actual import.Īnother option is to automatically set the region extents based on the Recommended to first use the -s flag to get the extents of the Parameter, the region extents will be based on new dataset. The -e flag along with the resolution=value Region extents and resolution are used for the import. Region settings (extent and resolution), as default the current Since the creation of raster maps depends on the computational The user may choose from a variety of statistical The r.in.lidar module loads and bins LAS LiDAR point clouds If not specified, all points are imported. Parameters: input= name LAS input file LiDAR input files in LAS format (*.las or *.laz) output= name Name for output raster map method= string Statistic to use for raster values Options: n, min, max, range, sum, mean, stddev, variance, coeff_var, median, percentile, skewness, trimmean Default: mean type= string Storage type for resultant raster map Options: CELL, FCELL, DCELL Default: FCELL zrange= min,max Filter range for z data (min,max) zscale= float Scale to apply to z data Default: 1.0 percent= integer Percent of map to keep in memory Options: 1-100 Default: 100 pth= integer pth percentile of the values Options: 1-100 trim= float Discard percent of the smallest and percent of the largest observations Options: 0-50 resolution= float Output raster resolution return_filter= string Only import points of selected return type If not specified, all points are imported Options: first, last, mid class_filter= integer Only import points of selected class(es) Input is comma separated integers.
