  2. Bearing (navigation) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(navigation)

    Thus, 32 points of 11.25° each makes a circle of 360°. An object at 022.5° relative would be 'two points off the starboard bow', an object at 101.25° relative would be 'one point abaft the starboard beam' and an object at 213.75° relative would be 'three points on the port quarter'. This method is only used for a relative bearing.

  3. Orientation (geometry) - Wikipedia

    en.wikipedia.org/wiki/Orientation_(geometry)

    In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies. [1] More specifically, it refers to the imaginary rotation that is needed to move the object from a reference placement to its current ...

  4. Bearing compass - Wikipedia

    en.wikipedia.org/wiki/Bearing_compass

    A bearing compass, is a nautical instrument used to determine the bearing of observed objects. (Bearing: angle formed by the north and the visual to a certain object in the sea or ashore). Used in navigation to determine the angle between the direction of an object and the magnetic north or, indirectly relative to another reference point.

  5. Geometric terms of location - Wikipedia

    en.wikipedia.org/wiki/Geometric_terms_of_location

    Orthogonal (or perpendicular) – at a right angle (at the point of intersection). Elevation – along a curve from a point on the horizon to the zenith, directly overhead. Depression – along a curve from a point on the horizon to the nadir, directly below. Vertical – spanning the height of a body. Longitudinal – spanning the length of a ...

  6. Direction (geometry) - Wikipedia

    en.wikipedia.org/wiki/Direction_(geometry)

    Three line segments with the same direction. In geometry, direction, also known as spatial direction or vector direction, is the common characteristic of all rays which coincide when translated to share a common endpoint; equivalently, it is the common characteristic of vectors (such as the relative position between a pair of points) which can be made equal by scaling (by some positive scalar ...

  7. Trilinear coordinates - Wikipedia

    en.wikipedia.org/wiki/Trilinear_coordinates

    In geometry, the trilinear coordinates x : y : z of a point relative to a given triangle describe the relative directed distances from the three sidelines of the triangle. . Trilinear coordinates are an example of homogeneous coordin

  8. Coordinate system - Wikipedia

    en.wikipedia.org/wiki/Coordinate_system

    In geometry and kinematics, coordinate systems are used to describe the (linear) position of points and the angular position of axes, planes, and rigid bodies. [16] In the latter case, the orientation of a second (typically referred to as "local") coordinate system, fixed to the node, is defined based on the first (typically referred to as ...

  9. Rhumb line - Wikipedia

    en.wikipedia.org/wiki/Rhumb_line

    Image of a loxodrome, or rhumb line, spiraling towards the North Pole. In navigation, a rhumb line, rhumb (/ r ĘŚ m /), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant azimuth (bearing as measured relative to true north).
