Some agencies are thinking about changing the accuracy testing to include accuracy testing on raw (unclassified) data. This testing would be bare earth accuracy testing in open areas. I have been thinking about any issues that could occur regarding this. I can’t see any issues with checking bare earth prior to classification of the data because these areas should already have the LiDAR points on the ground prior to classification as long as the data is properly Classified. Please feel free to comment on this because I would like to here other opinions on this.
