2.2 Display of Physical Environment at a Single Point A data of each physical environment can be represented by point symbol. (ex. Predicted point of strong tidal stream and observing point of sea fog) The symbol described by means occurrence of the physical environment at that place. Also, S-111(Surface Currents) and S-126(Physical Environment) are combined in last meeting of NIPWG 4(2017). We suggest more meaningful symbol instead of simple thing <Figure 2.3> to classify physical environment intuitionally. 2.2.1 Warning Symbol Shape Basically circular and include characteristic of each physical environment. It will be located at centre of portrayal domain when drawed on line or area. (centre of line or centre of gravity) In case of sea fog, the symbol was created with reference icon, internationally using by weather charts. Three horizontal lines mean fog symbol, so we gave shape like <Figure 2.1>, foggy cloud and horizontal lines on the sea.
