Reproject LAS File Sample Code

This ENVI LiDAR sample code shows how to reproject LAS file output. It provides information on how to:

  • Specify an input .las or .laz file, if one is not open.
  • Specify an output location and .las output type.
  • Reproject the data.
  • Write the reprojected points with projection information to a new .las file.
