terminology

**This is an old revision of the document!**

This terminology is generally sourced from Appendix A of 'Datums and Map Projections' (Iliffe & Lott 2008) based off the ISO 19111 terms.

Term | Comment |
---|---|

Coordinate | A sequence of n numbers designating the position of a point in n-dimensional space |

Coordinate conversion | Change of coordinates from one CRS to another in which the two CRSs are based on the same datum |

Coordinate operation | Change of coordinates with a 1-to-1 relationship, from one CRS to another. Comprised of coordinate conversion and coordinate transformation processes |

Coordinate reference system (CRS) | A coordinate system that through a datum, has defined position, scale and orientation with respect to an object (usually the Earth) |

Coordinate system | Set of rules defining how coordinates are assigned to points |

Coordinate transformation | Change of coordinates from one CRS to another, where the CRSs datums differ |

Datum | Defines the position of the origin, the scale and the orientation of the axis of a coordinate system with respect to an object |
