Antarctic Geodetic Vertical Marks

creation
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 http://www.linz.govt.nz/geodetic/datums-projections-heights/vertical-datums/.
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 http://www.linz.govt.nz/geodetic/datums-projections-heights/heights/height-orders/.
Note the accuracy applies at the time the mark was last surveyed - see the geodetic database for historical information about height coordinates.
This simplified geodetic vertical mark dataset has been created for easy viewing and downloading for the LDS.
It only contains marks which have authoritative heights in terms of a vertical datum. If horizontal or 3D mark positions are required please use the Geodetic Antarctic Mark Data (Simple) dataset.
More detailed data such as site photos or coordinate system position data is required please use the full geodetic datasets or directly refer to the web geodetic database at http://www.linz.govt.nz/gdb.

dataset
The original data comes from a geodetic database which was managed by LINZ and its predecessors.
This database contained a summary of the mark, coordinate and site information derived from survey observations and field sheets. The database was migrated into Landonline in 2000.
