I have written a third article for LiDAR News which addresses accuracies of Mobile LiDAR information. It may be accessed through this link.
The images in the article illustrate how we constrain our collections to ground control, much in the same was as aerotriangulation (AT) in Photogrammetry.
The table shown below (and included in the article) illustrates the difference between our check points (labeled Control) and the LiDAR point elevation at the corresponding locations. This methodology is used to calculate the accuracy per the National Standards for Spatial Data Accuracy.
Should you have a topic for discussion, please leave as a comment.
Thanks,
Stephen
