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.

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.

This layer was originally used to support electoral functionality within Landonline (Electoral Reports). This layer is no longer used for this purpose or maintained.

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 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 Mark is a physical monument placed for the purpose of being surveyed. A survey mark is a node which is occupied by a physical mark. This entity records the information that relates to mark type and maintenance. Marks connect Land Information NZ databases to the physical world and provide an infrastructure for other spatial systems such as topographic mapping, engineering, etc. Marks can be placed for a number of purposes e.g. geodetic, cadastral survey, boundary.
