How to Reduce Point-Cloud PDF Size?

With large point clouds containing many millions or 100s of millions of points, the shear size is too much for the Adobe Reader and the 3D PDF format to handle. So some reduction, decimation or simplification is required to get a reasonable result. A good rule of thumb is to aim for 1 million points in the PDF. For example if the input .pts, .las or other point cloud format contains 50 million point, a 50:1 reduction should be applied. On the “Gridding” tab of ReportGen, set the “subsample” parameter to 50. Also be sure to change the “Interpolation” mode to “Point Cloud”. A further more sophisticated technique is to use the Advanced tab Simplification options. See the manual chapter on this for a full explanation.
