Description: # Laspy
        
        Laspy is a python library for reading, modifying and creating LAS LiDAR
        files.
        
        Laspy is compatible with Python  3.6+.
        
        
        # Version 2.0
        
        laspy 2.0 is in alpha, and ready for you to test, to install, it add `--pre` to
        the pip install commands (eg  `pip install --pre laspy`)
        
        Examples
        --------
        
        Directly read and write las
        ```Python
        import laspy
        
        las = laspy.read('filename.las')
        las.points = las.points[las.classification == 2]
        las.write('ground.laz')
        ```
        
        
        Open data to inspect header (opening only reads the header and vlrs)
        
        ```Python
        import laspy
        
        with laspy.open('filename.las') as f:
            print(f"Point format:       {f.header.point_format}")
            print(f"Number of points:   {f.header.point_count}")
            print(f"Number of vlrs:     {len(f.header.vlrs)}")
        ```
        Use the 'chunked' reading & writing features
        
        ```Python
        import laspy
        
        with laspy.open('big.laz') as input_las:
            with laspy.open('ground.laz', mode="w", header=input_las.header) as ground_las:
                for points in input_las.chunk_iterator(2_000_000):
                    ground_las.write_points(points[points.classification == 2])
        
        ```
        
        Appending points to existing file
        
        ```Python
        import laspy
        
        with laspy.open('big.laz') as input_las:
            with laspy.open('ground.laz', mode="a") as ground_las:
                for points in input_las.chunk_iterator(2_000_000):
                    ground_las.append_points(points[points.classification == 2])
        ```
        
        API Documentation and tutorials are available at
        [ReadTheDocs](https://laspy.readthedocs.io/en/latest/).
        
        ## Installation
        
        Laspy can be installed either with `pip`:
        
        ```
        pip install laspy # without LAZ support
        # Or
        pip install laspy[laszip] # with LAZ support via LASzip
        # Or
        pip install laspy[lazrs] # with LAZ support via lazrs
        ```
        
        ## Changelog
        
        ### Version 2.0.0
        
        - Overhaul of the internals by essentially incorporating pylas into laspy,
          while the API to retrieve and set dimensions stayed the same, other parts changed
          and will require adaptation.
        - Better LAZ support
          * Added support for writing LAZ
          * Changed decompression mechanism by using either `laszip` python bindings (and not laszip-cli)
          or `lazrs`
        - Added ability to read and write LAS/LAS in `stream` / `chunked` mode.
        - Changed laspy to support the reading and writing of LAS/LAZ data from and to `file-objects` and `bytes`
        - Dropped support for python2.7, python3.6+ is supported.
        
        ### Version 1.7.0
        
        - Fixed bug in point record format 5, 9 and 10 [#105](https://github.com/laspy/laspy/issues/105)

        - Supprt numpy 1.17 [#122](https://github.com/laspy/laspy/issues/122)
        
        ### Version 1.6.0
        
        - Bug fix  [#92](https://github.com/laspy/laspy/issues/92)
        - Test creation of all valid custom dimension data types
        - Modify handling of extra bytes to be char data instead of numeric byte data
