Topo-bathymetric LiDAR form aerial platforms is an emerging technology that provides rapid surveying of shallow water areas that are difficult, dangerous, or impossible to get using water borne methods. Shallow water topo-bathymetric sensor and processing technology has advanced rapidly in the past few years, providing a seamless dataset of rivers and coastlines for use in a wide range of applications in both coastal and riverine environments. Topo-bathymetric LiDAR covers large areas efficiently and reaches areas too shallow for survey boats. Recent sensor advances drastically cut costs while improving resolution and accuracy. This presentation will provide a basic overview of the technology and an in-depth look at the wide range of applications for topo-bathymetric LiDAR.
