Element

<ArcByRadius>

Description

An arc generated based on the given parameters.� Child elements of LineStyle or PointText may be used to annotate the arc.

Example

• Arc is in a reverse direction

• Radius is based on the arc distance from the centre of the light

• Degree bearings for the start and end of the arc is determined from the SECTR1 and SECTR2 attribute values

• Line style is read from NLTSLACAR feature code.

Attributes

Name

Type

Description

radius

Double

Status: Mandatory

Radius in distance units of crs from the parent point geometry or central location.

sectorStart

Double

Status: Optional.

Degree bearing for start of arc based on crs. Default is 0.

sectorEnd

Double

Status: Optional.

Degree bearing for end of arc. Default is 0.

reverseBearing

Boolean

Status: Optional.

True means reverse the sector bearings by 180 degrees but use Sodano calculation based on length.

This parameter is useful for light sectors which are defined using the bearing from seaward.

Default is false or 0.
