Figure J.1 - Surface current arrow symbol, showing x- and y-coordinates of the vertices (mm) and the pivot point (+). Rule 2. A null value for speed and direction (see Table 12.1, gridLandMaskValue) means that the point represents land, or the value is missing. In either case, no arrow symbol is displayed. Rule 3. The colour of the arrow is set by the band within which the speed falls. The colours for nine speed bands are shown in Table J.1. Table J.1 - Speed bands, colour names, RGB colour values, and resulting day colours for current speeds.
