The SEWRPC Racine county project is to provide high accuracy bare-earth processed LiDAR data for the generation of 2 ft contours. The project consisted of acquisition, post-processing, and classification of LiDAR data. The classified bare-earth data achieved the following: All areas shall be collected at a nominal pulse spacing (NPS) of 1.3 meters based on Wisconsin State Plane South, related to the North American Datum of 1927 (NAD 27), National Geodetic Vertical Datum (NGVD 29) . Vertical accuracy was to achieve a RMSE Z of 0.50 ft (95% confidence level of less than 0.980 ft) or better in the "Open Terrain" land cover category for all areas. Accuracy statement is based on the area of moderate to flat terrain. Diminished accuracies are to be expected in areas in dense vegetation. The accuracy of the LiDAR data as tested met the vertical accuracy or better, however, derived products may be less accurate in areas of dense vegetation due to a lesser number of points defining the bare-earth in these areas.
