<p>This layer provides the extents of the data incorporated into an adjustment which has been completed as a Wide Area Cadastral Adjustment (WACA). These adjustments are undertaken in areas where there is already substantial survey-accurate data, but there are some inconsistencies in the data resulting from small changes to geodetic control coordinates and/or the progressive submission of additional Cadastral Survey Datasets (CSDs). The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be no more than 10cm, as the WACAs target areas where coordinates already have fairly high spatial accuracy.</p>

<p>This layer provides the extents of the data incorporated into an adjustment which has been completed as part of the Spatial Parcel Improvement (SPI) project. The SPI project aims to improve the accuracy of digital cadastral data in areas (primarily rural) where survey-accurate data does not currently exist. The improvement of coordinates is controlled by a mathematical adjustment process using a Least Squares methodology. The adjustment/integration process results in increased mapping accuracy of surrounding spatial objects (e.g. parcels), the effect of which is some new observations or parcels appear to move. The extent of the change largely depends upon the accuracy of the underlying data. In general, movements will be at least several metres, as the SPI project targets areas where significant movements are expected.</p>

<p>This layer provides survey mark information for marks that are not part of a parcel</p>
<p>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.</p>
<p>Note:<br>
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.</p>
<p>This dataset extends the Landonline stored data by including the network accuracy which is based upon its assigned Landonline order - refer LINZS25006 (<a href="https://www.linz.govt.nz/resources/regulatory/standard-tiers-classes-and-orders-linz-data-linzs25006?document=256">www.linz.govt.nz/resources/regulatory/standard-tie...</a>).</p>
<p>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.</p>

<p>A cadastral survey network mark is a node which is (or was) occupied by a physical survey monument that meets accuracy standards suitable for cadastral requirements. i.e. Cadastral Survey Network Marks have a NZGD2000 horizontal coordinate order of 6 or better. The complete definition for these mark orders is defined by the following Standard.<br>

• This commonly is in the form or a vector (bearing and distance), but occasionally just one component.<br>
• Some relationships are defined as arcs. In this data layer, the arc length is recorded in the distance field and a separate record holds the chord. </p>

<p>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). </p>
