Description: # jaklas
        
        jaklas is a thin wrapper around [``pylas``](https://github.com/tmontaigu/pylas) to make reading and writing las files as
        simple as possible.
        
        The main use case is to write a pandas array to a las file in a single function call.
        The las file attributes (point offset, point scaling, file version, point format, etc.)
        are inferred depending on column names, datatype and point values.
        
        The las writer supports any object implementing ``__getitem__`` that has the 
        correct field names.
        
        ## Installation
        ```bash
        git clone git@github.com:jakarto3d/jaklas.git
        cd jaklas
        python -m pip install .
        ```
        
        ### Testing
        ```bash
        pip install -r requirements-dev.txt
        pytest
        ```
        
        ## Usage
        ``jaklas.write`` writes a pandas dataframe (or a dict) to a las file.
        
        The dataframe **must** have either (case insensitive):
        - 'x', 'y' and 'z' columns 
        - or an 'xyz' column
        
        and it can have other las attributes (case sensitive names taken from ``pylas``):
         - gps_time
         - intensity
         - classification
         - red
         - green
         - blue
         - edge_of_flight_line
         - key_point
         - nir
         - number_of_returns
         - overlap
         - point_source_id
         - raw_classification
         - return_number
         - return_point_wave_location
         - scan_angle
         - scan_angle_rank
         - scan_direction_flag
         - scanner_channel
         - synthetic
         - user_data
         - wavepacket_index
         - wavepacket_offset
         - wavepacket_size
         - withheld
         - x_t
         - y_t
         - z_t
        
        other column names will be written as extra dimensions.
        
        ## Example
        
        ```python
        import jaklas
        import pandas
        
        data = {
            'gps_time': [0, 1.232, 2.543, 3.741],
            'intensity': [14578, 54236, 1425, 12543],
            'X': [456, 234, 567, 432],
            'Y': [10234, 10256, 10789, 10275],
            'Z': [10, 11, 12, 13],
        }
        dataframe = pandas.DataFrame(data)
        filename = 'example.las'
        jaklas.write(dataframe, filename)
        ```
        
        Note the upper case 'X', 'Y' and 'Z' point data are the real coordinates,
        not the scaled int32 ones like in the las file.
        
        See [``jaklas.write``](https://github.com/jakarto3d/jaklas/blob/master/src/jaklas/write.py) docstring for more options like controlling offset and scaling.
