Tag:seamark:type=light_float

A boat-like structure used instead of a light buoy in waters where strong streams or currents are experienced, or when a greater elevation than that of a light buoy is necessary.

Use seamark:type=light_major for major navigational lights.

Sectored light attributes

Note that sectored lights must bear a sector number (# = 1, 2, 3, ...) even if there is only one sector.
For more information on tagging sectored and directional lights, see: sectored and directional lights.

Example for each sector (# is a number):

• seamark:light:#:category
• seamark:light:#:character
• seamark:light:#:colour
• seamark:light:#:height
• seamark:light:#:period
• seamark:light:#:sequence
• seamark:light:#:range
• seamark:light:#:sector_start
• seamark:light:#:sector_end

Light category

Category Beacon as upper, lower, directional

• seamark:light:1:category=*

Light character

Rhythm of light

• seamark:light:1:character=*

Light colour

• seamark:light:1:colour=*
  • seamark:light:1:colour=white
  • seamark:light:1:colour=green
  • seamark:light:1:colour=red

Light group

The number of flashes, the combination of flashes or the Morse character(s) within one period of full sequence.

• seamark:light:1:group=*

Light period

Time of the time occupied by an entire cycle of intervals of light and eclipse.

• seamark:light:1:period=*

Light sequence

The sequence of times occupied by intervals of light and eclipse for all 'light characteristics' except for occulting where the sequence of times is occupied by intervals of eclipse and light.

• seamark:light:1:sequence=*

Light range

The nominal range at which the light can be seen in nautical miles.

• seamark:light:1:range=*

Light sector start

The sector limit 1 specifies the first limit of the sector. The order of sector limit 1 and sector limit 2 is clockwise around the light.

• seamark:light:1:sector_start=* - in decimal degrees

Light sector end

The sector limit 2 specifies the second limit of the sector. The order of sector limit 1 and sector limit 2 is clockwise around the light.

• seamark:light:1:sector_end=* - in decimal degrees

Light height

The vertical elevation of the actual lamp or light source (in meters) above the specified vertical datum (typically, mean sea level) – known as the focal height.

• seamark:light:1:height=*

Light visibility

Shows the visibility of light.

• seamark:light:1:visibility=*

Light exhibition

Shows what time the light is on.

• seamark:light:1:exhibition=*
