The source data exists in order to provide linear geometries against which official railway names can be recorded and to provide contextual data for Landonline users.

A railway centreline in this layer will typically consist of a centreline wholly contained with a parcel(s) with an intent of "railway"

The railway centrelines do not represent actual railway formation but the presence, and general location of a gazetted railway for contextual uses.

This dataset was first added to LINZ Data Service on 18 Oct 2011.

Note: LINZ and Opus International have recently agreed a contract for the maintenance of the Crown aerial imagery archive, following the liquidation of New Zealand Aerial Mapping in September 2014.

The following Information on product sales has been updated to reflect this.

This layer has been provided to enable potential users to identify the coverage of photography for Mainland NZ flown on behalf of the Crown between 1936 and 2005. Areas flown outside of Mainland NZ will be added later. The original data used to create this layer was compiled prior to 2000 and it is possible that some errors exist in the data fields. If you are aware of any inaccuracies, please contact LINZ: info@linz.govt.nz or +64 4 4600110. The layer shows the extent of each aerial survey undertaken. The 'NZ Aerial Photo Footprints 1936-2005 poly' layer shows the extent of each photograph in the survey.

The Collection exists as photographic negatives (most are not in digital form) so the images are not downloadable from the LDS.

The Crown Aerial Film Negative Collection is managed for LINZ by Opus International.

You can are order images from the Collection from Opus International in a number of formats, including:
- contact prints
- enlargements
- digital files
- precision scans for photogrammetric production
- orthophotos

You will need to tell Opus NZ the survey number (the value in the ‘SURVEY’ attribute) covering your area of interest.

Opus NZ will be able to provide information about the cost of providing images in the various formats. Contact them at: photosales@opus.co.nz or 0800 680 690

There are a small number of images held in the Collection that have not been referenced in the LDS layers due to incomplete metadata. LINZ is currently investigating ways this can be remedied. Opus International will be able to let you know if additional photographs are available in your area of interest.

There are also a large number of images which previously belonged to New Zealand Aerial Mapping and which are now are available for public use. The extents of these may be added to the LDS in future. You can order these images by contacting Opus International.

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.

This layer provides the current Hydro parcel polygons with associated descriptive data.

The combination of this layer with the other land parcels and road parcels equates to the primary parcels layer which provides all current parcels for New Zealand (i.e. excludes historic and pending parcels).

This set of three parcel layers (land, road and hydro) enables easy access to the most common groupings of parcel intents (excluding non primary parcels).

If you require approved or historic parcels see the All Parcels Layer

This layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the Survey Boundary Marks layer which contains accuracies for each parcel node.

The originating data for parcel/title associations includes some non-official sources where the official data does not support a link. For more information see

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 a 3D New Zealand official geodetic datum. The horizontal positions of marks are provided for approximate location purposes only .

This dataset only contains marks that are within the New Zealand mainland and offshore islands. The height data for these marks have been generated using precise levelling from datum tide gauges, or has been acquired by 3rd party sources either as levelling observations or direct heights.

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 provides survey mark information for marks that are not part of a parcel

A non-boundary mark is any survey mark that is not on a boundary point. The points in this dataset represent physical survey monuments usually placed for cadastral requirements. The data set also includes geodetic marks. Non-boundary marks now enter the Landonline system predominately as part of a cadastral survey dataset (plan) and occasionally via the geodetic processes. For Cadastral marks (i.e.the majority) its name consists of a mark type and number (and is unique to that survey), followed by the ‘plan’ number e.g. IS I DP 3456; IS II DP3456.

Note:
Non-boundary marks used to connect cadastral surveys to the geodetic network are those of 6th order (or better) and this subset is available as the NZ Cadastral Survey Network Marks layer.

This dataset extends the Landonline stored data by including the network accuracy which is based upon its assigned Landonline order - refer LINZS25006 (www.linz.govt.nz/about-linz/news-publications-and-...).

The accuracy provided relates to the accuracy of coordinates of the mark and has little relevance to the accuracy of the boundary in relation to other boundaries. For example, if the coordinates of the mark were used to locate it, a user would expect to find the existing mark within the accuracy (distance) stated.
