Abstract This Product Specification describes a data model and format for a coverage data product consisting of water level data for a particular geographic region and set of times, along with the accompanying metadata describing the content, variables, applicable times, locations and structure of the data product. Water level data is the height of the water observed, mathematically-predicted or forecast values. The coverage consists of points organized in a regular grid and the water level data are intended to be used for adjustment of depth information in an underlying ENC or bathymetry product.
