Historically, nautical products are updated using data derived from traditional survey methodologies. The methodology for deriving bathymetry using satellites and airborne sensors has matured over the past decade. As a result of this technological change, policy regarding the incorporation of this data into nautical products must also change. Recent policy changes have allowed NOAA’s Marine Chart Division to adapt the use of a Satellite Derived Bathymetry (SDB), Airborne Lidar Bathymetry (ALB), and Automated Information System (AIS) technologies into a procedure that allows for the information to be applied to nautical products. This procedure can open the door to a myriad of other possibilities which hydrographic offices around the world can use to improve the safety of navigation in appropriate use cases. The first-year’s results already provide a rapid and cost-effective solution to update nautical charts in areas of dynamic seafloor change both nationally and internationally. The development of this standardized procedure can be transferable to cartographers, hydrographers and potential chart producers from hydrographic offices and government agencies around the world. This paper will provide a brief review of policy, procedure and real world applications.
