This dataset was last updated on LINZ Data Service on 17 Aug 2019.

This dataset provides information about the survey control network, position, position accuracy, mark name, mark type, condition and unique four letter code for geodetic marks in terms of New Zealand's official geodetic datum, New Zealand Geodetic Datum 2000 (NZGD2000).

The dataset only contains marks that are within the New Zealand mainland and offshore islands. These positions have been generated using geodetic observations such as precise differential GPS or electronic distance and theodolite angle measurements. The positions are either 2D or 3D depending of the availability of this measurement data.

The source data is from Land Information New Zealand's (LINZ) Landonline system where it is used by Land Surveyors. This dataset is updated daily to reflect changes made in the Landonline.

The mark network is segmented into six control networks which provide control marks for specific purposes. The control_network field within this layer records this network with the 3 or 4 letter abbreviation code as follows:

NRF - National Reference Frame NDMN - National Deformation Monitoring Network RDMN - Regional Deformation Monitoring Network LDMN - Local Deformation Monitoring Network CHN - Cadastral Horizontal Control Network CVN - Cadastral Vertical Control Network BGN - Basic Geospatial Network NHN - National Height Network

Note a geodetic mark can be in more than network. Also not all geodetic marks are currently associated with a geodetic network. Those that are may be referred to as a control mark. For more information about the control networks refer to www.linz.govt.nz/geodetic/geodetic-programme/surve....

Accuracy

Geodetic marks with a coordinate order of 5 or less have been positioned in terms of NZGD2000. Lower order marks (order 6 and greater) are derived from cadastral surveys, lower accuracy measurement techniques or inaccurate historical datum transformations, and may be significantly less accurate.

The accuracy of NZGD2000 coordinates is described by a series of 'orders' classifications. Positions in terms of NZGD2000 are described by three-dimensional coordinates (latitude, longitude, ellipsoidal height). The accuracy of a survey mark is indicated by its order. Orders are classifications based on the quality of the coordinate in relation to the datum and in relation to other surrounding marks. For more information see www.linz.govt.nz/geodetic/datums-projections-heigh...

Note that the accuracy applies at the time the mark was last surveyed. Refer to the web geodetic database for historical information about mark coordinates.

Note also that the existence of a mark in this dataset does not imply that there is currently a physical mark in the ground - the dataset includes destroyed or lost historical marks. The geodetic database provides more information on the mark status, valid at last time it was visited by LINZ or a maintenance contractor.

Accuracy

Geodetic marks with a coordinate order of 5 or less have been positioned in terms of Ross Sea Region Geodetic Datum 2000 (RSRGD2000) using precise differential GPS techniques. Marks with order 6 have been positioned in terms of RSRGD2000 using precise horizontal angles and distance measurements. Lower order marks (order 7 and greater) are derived from lower accuracy measurement techniques or historical datum transformations, and may be significantly less accurate.

This dataset provides information about the position, height, height datum, height accuracy, mark name, mark type, condition and unique four letter identifier for geodetic marks that have an authoritative height in terms of a vertical datum.
Heights are in datums defined at www.linz.govt.nz/geodetic/datums-projections-heigh....

All marks will have positions in terms of New Zealand’s official geodetic datum for Antarctica, Ross Sea Region Geodetic Datum 2000 (RSRGD2000). The horizontal positions of marks are provided for approximate location purposes only.

This dataset only includes marks that are within the Antarctic region. The height data for these marks have been generated primarily using precise vertical angle and slope distance measurements from datum tide gauges. Some have been generated from levelling data.

The source data is from Land Information New Zealand's (LINZ) Landonline system where it is used by Land Surveyors. This dataset is updated daily to reflect changes made in the Landonline.

Accuracy

The accuracy of normal-orthometric heights are described by height orders.

For more information see www.linz.govt.nz/geodetic/datums-projections-heigh....

Note the accuracy applies at the time the mark was last surveyed - see the geodetic database for historical information about height coordinates.

This layer identifies critical survey marks which LINZ requires to be physically protected.

Thousands of vital survey marks exist in New Zealand. Many of them are below or at ground level and not noticed by most of us.

People involved in construction work are responsible for making sure survey marks are not damaged. When building works have the potential to destroy existing cadastral and geodetic marks, LINZ needs to be notified so that it can assess whether the marks should be reinstated or replaced. Find out more about looking after the national survey network

Please note there may be other important survey marks not identified on this layer, and that LINZ recommends consultation with a Licensed Cadastral surveyor before any construction or earthworks begin.

If you notice a damaged survey mark, you can report it to LINZ by filling out a form on this website

This table is used to associate live and part-cancelled Records of Titles to current spatial parcels. There is a many to many relationship between titles and parcels.

This table can be used to link NZ Property Titles List, NZ Property Title Estates List, or NZ Property Title Owners List to spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels

.

The match between live/part-cancelled titles and current parcels is more than 99%.

Note: The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. If you find an link that has a source of 'External' that you believe to be incorrect, please contact us.

This table is used to describe the many to many relationship between surveys and parcels. This is a table to link NZ Survey Plans data with spatial parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels.

An affected parcel is a parcel which is affected by the approval of a survey dataset. A parcel may be affected, created or extinguished. For example, a survey can affect extinguish parcels by rendering them historical and at the same time may create new parcels (subdivision). Parcels may be affected by a survey but remain current (definition of an easement etc).

For more information about this table and other tables and layers that make up this dataset refer to the support documentation.

This table provides information on Records of Title that are live and part-cancelled.

This table contains top level, general title data only, such as the title number, type (e.g. Freehold, Unit Title, Cross Lease etc) and status.

A Record of Title is a record of a property's owners, legal description and the rights and responsibilities registered against the title.

If you need more detailed title data such as the legal description, please refer to the NZ Property Titles Estate List table.

This table does not contain ownership data. This is available in the NZ Property Title Owners List table. This is a restricted access dataset and requires you to agree to the LINZ Licence for Personal Data.

For title data that is directly linked to parcel shapes (property boundaries) refer to NZ Property Titles or NZ Property Titles Including Owners. Please note that these datasets are much larger to download, contain duplicated parcel shapes (one for each title that relates to the parcel) and does not contain all of the columns that this table has.

For more information about this table, other property datasets, and how to relate them to each other, refer to the Property Boundary and Ownership Data Dictionary.

This table provides registered (or current) Record of Title estate data.

A Title estate is a type of ownership of a piece of land e.g. fee simple estate, leasehold estate. Estates are used to link the registered owners to the Record of Title. A Record of Title can have more than one estate and type.

This data enables linking between the title information provided in the NZ Property Titles List and registered ownership information in the NZ Property Titles Owners List. Note: The registered owner dataset a restricted access dataset and requires you to agree to the LINZ Licence for Personal Data.

This table can also be linked to the spatial parcel data using the NZ Title Parcel Association List, although care is necessary when making this relationship (refer to the table metadata).
