Topobathy LiDAR is the combination, or parallel collection of traditional terrestrial LiDAR and bathymetric LiDAR. Here we will walk through the process of creating a high-quality topobathy Digital Elevation Model utilizing a portion of the 2014 NOAA National Geodetic Survey (NGS) Topobathy LiDAR data.
This blog posting will build on the Obtaining Elevation Data from NOAA Digital Coast blog post and introduce you to working with LiDAR data within the LAS dataset environment. A LAS Dataset is one of the Esri storage methods for LiDAR data in the LAS file format. Here we will explore creating two of the most basic outputs, the Digital Elevation Model and the Hillshade Model.
