    1616This stage of the processing takes the raw scanner files and georeferences them to create a point cloud of the data. This is usually in the binary LAS format but may be output as ASCII if you wish.  This uses the ALSPP software, however it is recommended you use alsproc for roll and pitch corrections.

    2122After running the ALSPP check the % of first returns column in the main window. This should be high (probably >95%). If not then it may be an indicator to problems with the data (such as a large % of cloud coverage)
