Accuracy testing

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.

    I dont see how points get any more/less accurate after classification? Unless people are filtering out ground points, or they are being incorrectly classified – in which case i suppose it could be useful.

    Maybe they are afraid people are manipulating the data in the processing stage?
