This layer provides all linear parcels (e.g. Centreline easements) and their associated descriptive data as a single layer to facilitate their use independently of the all polygon parcels.
**NOTE**: This layer contains [primary](http://data.linz.govt.nz/layer/772) and [non-primary](http://data.linz.govt.nz/layer/782) approved, current or historic linear parcels (see status flag descriptions for more information).
In conjunction with the [Parcels](http://data.linz.govt.nz/layer/1571-nz-parcels), this layer provides the easiest way to create a relationship with associated tables such as [Parcel Title Association List](http://data.linz.govt.nz/table/1569-nz-title-parcel-association-list), [Parcel Statutory Actions List](http://data.linz.govt.nz/table/1565-nz-parcel-statutory-actions-list) and [Survey Affected Parcels List](http://data.linz.govt.nz/table/1568-nz-survey-affected-parcels-list).
This layer contains spatial and non-spatial (without geometry) parcels. The Landonline system which manages the data maintains non-spatial parcels for many different reasons. The non-spatial parcels can only be accessed via WFS or as a full layer file download. No layer clips can be used. The most common reasons for non-spatial parcels are:
1. Flats and unit survey plans will create non-spatial parcels for referencing property rights. This is because the Landonline system has not yet been designed to support the spatial definition of these plans.
2. Titles which were not linked to a spatial parcel during the Landonline title conversion project created non-spatial parcel references. As titles are spatially linked many of these non-spatial parcels will be made historic or will be merged with the associated spatial parcel.
Parcels within this layer contain the following status flags:
- Approved: The definition of a survey-defined parcel that has been processed and authorised as correct in terms of the survey network.
- Current: A parcels that has been registered or the parcel is made current by a statutory action against a Legalisation plan.
- Survey Historic: A parcel that has been extinguished from the primary cadastral network but still exists in live Title estates.
- Historic: A parcel that has been extinguished from the primary cadastral network and no longer exists in live Title estates or has an current recorded statutory action. Typically this happens when a parcel is subdivided or merged, and new titles or actions are registered against the replacing parcels. Note: Only parcel made historic since the beginning of Landonline operations (2002) are included. See this [page](http://www.linz.govt.nz/survey-titles/landonline-data/landonline-bde/related-datasets/dcdb-datasets) for the actual dates when Landonline operations started.
The Linear parcels within 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](http://data.linz.govt.nz/layer/774-nz-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](http://www.linz.govt.nz/about-linz/linz-data-service/dataset-information/cadastral-titles-data).
LINZ and its predecessors have been responsible for cadastral data in New Zealand for more than a hundred years.
National mapping of parcels was undertaken as part of the maintenance and indexing roles with scales ranging from 1:396 (50 links to an inch) to 1:50,000. The predominant scales in urban areas were 1:792, 1:1000, 1:1584 and 1:2000. Predominant rural scales were of 1:7920 and 1:10,000.
The first digital data was created in the late 1980’s (along with the creation of the Department of Survey and Land Information) by hand digitising the department's cadastral record maps into the digital cadastral database (DCDB). The DCDB provided the graphical index to survey records throughout New Zealand until the implementation of Landonline (2000-2002). As Landonline was rolled out to each Land District, that district’s DCDB data was converted into the Landonline database (also known as the Core Record System or CRS) and then decommissioned. The survey conversion project scanned survey plans and converted them to 1.4 million electronic files. Additionally, boundary dimensions for a total of 1.4 million parcels were captured from around 300,000 surveys. This involved the capture of some 13 million observations and the adjustment of five million geodetic survey marks.
Unlike the prior systems that subsequently mapped cadastral records, Landonline is 'live' amd reflects realtime transactions as it enables surveyors, lawyers and other land professionals (including Territorial Authorities) to search and lodge title dealings and survey data digitally. New parcel shapes is therefore survey accurate. However as the change to parcels (attributes or shape) is mainly driven by the subdivision process, only a small portion of the parcels dataset will be changing at any given point of time.
