For a simplified version of data contained within this table see our property ownership and boundary data.

This table stores one record for each ring in a polygonal (e.g. fee simple) parcel or for the line sequence of a lineal (e.g. centreline) parcel. A polygonal parcel may have multiple rings, some of which may be exterior (i.e. polygons) or interior (i.e. holes). If a ring is an inner ring, its parent (i.e. bounding exterior ring) is specified in pri_id_parent_ring; otherwise, this field is NULL. The Parcel Ring record may not actually be a ring in the case of a lineal (e.g. centreline) parcel. The actual sequence of lines that define the ring is contained in the Parcel Boundary table.

An Adjustment is a mathematical process of generating corrections to Reduced Observations and Coordinates to generate a consistent set of adjusted Coordinates and adjusted Reduced Observations. The adjusted Reduced Observations are able to be re-generated from the adjusted Coordinates and are therefore not retained. Inputs are, Reduced Observations, Observation Accuracy, Coordinates and constraints which are defined by Adjustment Method and Adjustment Coefficients. The primary outputs are adjusted Coordinates, Coordinate Accuracy (again in the form of a VCV matrix) and identification of suspect Reduced Observations.The Adjustment entity contains information about the network adjustment process including, the type of adjustment model used, constraints applied, source, etc.

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.

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.
