Observation includes Reduced Observations. It may include data recorded in the field that impacts on the Observations such as meteorological observations, time of measurement, etc.

A collection of observations which are related in some way which is useful for administration or to simplify processes. An example is a set of theodolite directions. These all have a common orientation uncertainty and are grouped as such in a network adjustment.

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.

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.

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.

Instruments can be made up of one or more actions. Actions are used to perform the actual operations of titles transactions. This table contains all the valid action types.

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 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.

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.
