Physical conditions of oceans (currents, salinity, wave heights, etc.).
An Ocean Geographical Feature (OF) represents the (physical or chemical) properties of a Sea Region. This type of information is essentially a coverage describing the ocean and could be presented as a set of point data, gridded data, but also as vertical profiles through ocean depths and trajectories along the ocean surface. The Ocean Geographical Features theme employs the ISO 19156 Observations and Measurements standard for consistent encoding of measured, modelled or simulated data.
