Dec 27, 2018 · It compresses bulky LAS files into compact LAZ files that are only 7-20 percent of the original size, accurately preserving every single bit. For example, compressing and decompressing the LAS file lidar.las with laszip.exe (command-line only laszip-cli.exe) as shown below results in lidar_copy.las that is bit-identical to lidar.las. From Las specification. X, Y, and Z scale factors: The scale factor fields contain a double floating point value that is used to scale the corresponding X, Y, and Z long values within the point records. The corresponding X, Y, and Z scale factor must be multiplied by the X, Y, or Z point record value to get the actual X, Y, or Z coordinate.If the las file has been classified, you can choose what groups to export, and you can resample the data to reduce file size if needed. You should be able to import the XYZ files into Civil3D just like any other text file. If you guys use Trimble gear or software, TBC handles las and laz files super smoothly just with a drag and drop. ...

It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used and regarded as an industry standard for lidar data.The Global Encoding Bytes in an LAS file is a bit field used to indicate certain global properties about the file. In LAS 1.2 (the version in which this field was introduced), only the low bit is defined (this is the bit, that if set, would have the unsigned integer yield a value of 1). This bit field is defined in the LAS v1.4 specification as:The LAS file format is a binary file format specifically for the interchange between vendors and customers. Overall, LAS files maintain information specific to LIDAR without the loss of information. LAS files are available for public use, unlike ASCII and other proprietary file formats.

The Point Cloud toolset contains tools for converting LAS files and interpolating raster surfaces from point clouds. The LAS format was designed to store discrete returns from lidar surveys in an efficient binary data structure. Over time, it has also become the destination for point clouds from sources other than lidar.

The LAS dataset allows you to examine LAS files, in their native format, quickly and easily, providing detailed statistics and area coverage of the lidar data contained in the LAS files. A LAS dataset can also store references to feature classes containing surface constraints. Available with 3D Analyst license. A LAS dataset stores references to one or more LAS files on disk, as well as to additional surface features. A LAS file is an industry-standard binary format for storing airborne lidar data. Optimized LAS (.ZLAS) files are also supported with the LAS dataset.
