<p><strong>For further information about this dataset, see <a href="http://www.linz.govt.nz/land/surveying/canterbury-earthquakes/information-for-canterbury-surveyors-post-earthquake-cadastral">the Canterbury earthquake information</a>.</strong></p>
<p>Coordinates computed by adding the effects of deep-seated movement to survey points that had authoritative survey-accurate digital cadastre (SDC) coordinates immediately prior to 4 September 2010 (the first Canterbury earthquake). Marks that did not have SDC status at that time are not included in the dataset. Deep-seated movements were evaluated using the NZGD2000 deformation model.</p>
<ul>
<li>The 'nod_id' column is the Landonline node id. This is the unique identifier for the mark. </li>
<li>The 'current_name' column is the Landonline mark name. Many boundary marks do not have a name recorded in this dataset, because this information has not been digitally captured. </li>
<li>The 'east_mtpleatm2000' and 'north_mtpleatm2000' columns are the east and north coordinates (metres) in terms of the Mt Pleasant 2000 transverse mercator projection. Rounded to the nearest centimetre. </li>
<li>The 'coord_order' column is the Landonline coordinate order immediately prior to 4 September 2010. </li>
</ul>
<p>The estimated absolute uncertainty of these coordinates is 0.09m at the 95% confidence level.</p>
<p>These coordinates are intended for the use of Licensed Cadastral Surveyors when locating boundaries in Christchurch, in accordance with the Rules for Cadastral Survey 2010 and associated guidance, particularly <a href="http://www.linz.govt.nz/land/surveying/canterbury-earthquakes/information-for-canterbury-surveyors-post-earthquake-cadastral">guidance relating to the earthquakes</a>.</p>
