Total Propagated Uncertainty (TPU) and Absolute Accuracy...
Total Propagated Uncertainty (TPU)  is the statistical estimate of lidar positional uncertainty for each lidar point. Theoretical details of the TPU and its application to the airborne lidar data will be presented. Assessment of the 3D absolute accuracy of the lidar point cloud is an important priority in USGS 3DEP program. TPU is an important factor that affects the absolute accuracy of the lidar point cloud data. Techniques for the 3D absolute accuracy assessment using various geometric features and its inherent relationship with TPU will be discussed in the workshop.
