Algorithm Description

The LAS Reader supports reading from LAS format files, the standard interchange format for LIDAR data. The reader does NOT support point formats containing waveform data (4, 5, 9 and 10). This algorithm is ported from the excellent PDAL - Point Data Abstraction Library. For more information please refer to https://pdal.io.

Parameters

Name	Description	Data Type	Required?
compression	May be set to “lazperf” or “laszip” to choose either the LazPerf decompressor or the LASzip decompressor for LAZ files.	string
count	Maximum number of points to read.	integer
extra_dims	Extra dimensions to be read as part of each point beyond those specified by the LAS point format. The format of the option is <dimension_name>=<type>, … where type is one of: int8, int16, int32, int64, uint8, uint16, uint32, uint64, float, double. _t may be added to any of the type names as well (e.g., uint32_t).	string
filename	LAS file to read.	string
spatialreference	Spatial reference to apply to the data.	string
use_eb_vlr	If an extra bytes VLR is found in a version 1.0 - 1.3 file, use it as if it were in a 1.4 file. This option has no effect when reading a version 1.4 file.	string
