Data

Please read: This layer is part of the comprehensive Full Landonline Dataset and is designed for use only by data professionals who require the complex version of our property ownership and boundary data for advanced uses.

This layer defines the extent of the official coordinate systems that are used for the definition of coordinates associated with nodes. It is mandatory for every coordinate to have one and only one authoritative coordinate in the official coordinate system.

Please refer to the LDS Full Landonline Data Dictionary and Models for detailed metadata about this layer.

This table contains details of ellipsoid used for a datum. The ellipsoid represents the curvature of the datum to match the curvature of the earth.

A Datum is a complete system for enabling Coordinates to be assigned to Nodes. A datum is prescribed by the appropriate authority from which it derives its validity. All Coordinates will be in terms of a Datum. A Datum also provides a spatial standard for the alignment of Reduced Observations via a Datum Calibration. Most Reduced Observations are Datum dependent but there are specific Reduced Observation types which are Datum independent. The Datum entity contains information about the official geodetic Datum used in Land Information NZ databases and other important Datum’s used to spatially reference source data (e.g.. Reduced Observations) or output data or products (e.g.. Coordinates, Digital Cadastral Database, topographic maps, hydrographic charts, etc). The Datum entity includes objects which, strictly, are reference frames rather than datum’s but the distinction is a fine technical point which is of no great consequence. The Datum entity includes vertical reference surfaces such as leveling datum’s, various tidal surfaces including Mean Sea Level, the geoid, datum ellipsoids, etc. For a Datum to maintain accuracy over a significant area it must be geodetic. Examples of non-geodetic datum’s are the Old Cadastral Datums. These do not account for the curvature of the earth and therefore can only maintain accuracy over a limited part of the earth's surface.

This table contains information about the different forms that coordinates can take within a datum. For example, Geocentric Cartesian (X, Y, Z); Topocentric Cartesian (East, North, Up): Geodetic (Latitude, Longitude) or (Latitude, Longitude, Height), Astronomic (Latitude, Longitude) Projection (North, East) in various projections, Orthometric Height, Ellipsoidal Height, Geoid Height, Gravitational Potential, etc.

An associate table that resolves the many-to - many relationships between Datum and Coordinate Type. Coordinates are expressed in terms of a Coordinate System. For example, Coordinates may be expressed as latitude and longitude (a Coordinate Type) on New Zealand Geodetic Datum 1949 (a Datum). Transformations operate between Coordinate Systems. For example, a transformation may relate Cartesian Coordinates on NZGD49 to Cartesian Coordinates on WGS84.
