A universal hydrographic data model that underpins a family of numbered product specifications: S-101 for ENCs, S-102 for gridded bathymetric surfaces, S-104 for water levels, S-111 for surface currents and S-124 for navigational warnings. It carries gridded and time-varying data that S-57 cannot, so ships can overlay dense bathymetry and live water levels on the chart.
Client wants the deliverable as an S-102 grid as well as the ENC update.
