Koordin

Koordin is a term used in some technical communities to denote a coordinate data unit—the information that locates a point within a given reference frame. In practice, a koordin represents an ordered tuple of numbers describing position in a space, optionally accompanied by metadata such as the reference frame, units, precision, and a timestamp.

A koordin typically consists of two parts: the coordinate values and the associated metadata. The values define position in n-dimensional space (for example, x and y in 2D or x, y, z in 3D). The metadata records the reference frame (Cartesian, cylindrical, spherical, or geographic), the unit system (meters, degrees, etc.), and precision.

Common types include 2D koordin, 3D koordin, and geographic koordin (latitude and longitude, with optional height). In computer graphics and robotics, coordinates are often represented as koordin vectors or as homogeneous koordin to simplify transformations.

Applications of koordin span mapping, computer-aided design, simulations, robotics, and geographic information systems. They are transformed between frames by matrices or conversion formulas and can be subject to rounding errors, measurement uncertainty, and frame mismatches.

Etymology and status: The word koordin is a shortened or stylized form of coordinate used in some languages or communities, distinct from the standard term coordinate or koordinat. It is not a universally standardized term, and its exact meaning can vary by domain or software ecosystem.
