Abstract
This paper presents a comprehensive total vertical uncertainty (TVU) model for topo-bathymetric Light Detection and Ranging (LIDAR) systems. The TVU model consists of a combination of analytical uncertainty propagation for the subaerial (above water) portion and Monte Carlo simulation models for the subaqueous portion (water surface to seafloor). The TVU model was tested on a topo-bathymetric LIDAR data set collected by National Oceanic and Atmospheric Administration's National Geodetic Survey (NGS) in Southwest Florida, U.S., in May 2016 using a Riegl VQ-880-G topo-bathymetric LIDARsystem. The TVU values were compared against the empirical standard deviation and were found to capture the variability of uncertainty with depth while providing (slightly) conservative estimates of uncertainty. The results may be used to inform data acquisition protocols and data processing models. The model implementation is now beginning to be used operationally at NGS for topo-bathymetric LIDAR projects.
