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
LIDAR system. 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.
