Class: CoordinateSystem

A coordinate system is a specification for spatial location that uses a set of numbers, or coordinates, to uniquely determine the position of a point or other geometric element.

Parents

• is_a: SpatialSpecification - A specification for spatial location is an effective specification towards representation spatial position or spatial data.

Children

• CartesianCoordinateSystem - A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length.
• CylindricalCoordinateSystem - A cylindrical coordinate system is a three-dimensional coordinate system that specifies point positions by the distance from a chosen reference axis, the direction from the axis relative to a chosen reference direction, and the distance from a chosen reference plane perpendicular to the axis.
• PolarCoordinateSystem - A polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a fixed point and an angle from a fixed direction.
• SphericalCoordinateSystem - A spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuth angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane.
