A Reduction Run is a mathematical process of reducing raw observations to generate a set of reduced observations (in the case of GPS observations, this results in the generation of baselines). The Reduction Run entity contains information about the filtering and quality measures applied in relation to the reduction method used.

The Setup table holds information about a set-up at a Node as a result of a type of Work such as a Survey. The setup entity forms the link between an observation and the nodes that the observation is between.

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.

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.

A Statistical Area Class, e.g. Territorial Authority, may have more than one version. Versioning allows both the former and latter versions of statistical area boundary changes to be stored in Landonline.

This table defines all of the different types of observations. Observations are can be split into two types raw or reduced. For raw observations the following subtypes exist: GPS raw data, theodolite pointing, EDM slope observation, level foresight/backsight, meteorological readings, etc. For Reduced Observations the following subtypes exist: GPS baseline, GPS multi-station set, GPS point position, Doppler point position, theodolite direction etc.

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.
