Subject: Barron Co, WI - Preliminary Accuracy Assessment Report
Mark,
 
There are several reports you will get including Meta Data that we usually deliver at project completion, however, I thought you might like a preliminary copy of the accuracy assessment.  It is a spread sheet that compares the field surveyed cross section data to the LIDAR bald earth DTM data.  I can give you a copy of the Excel spread sheet we put together if you like.  If you take the LIDAR bald earth DTM data we delivered several months ago and compare it to the ground truth surveys you provided to us and then subtract 5% outliers, you should come up with the same results we did which is the RMSE accuracy at the 95%.
