This dataset was last updated on LINZ Data Service on 30 May 2020.

This dataset provides information about the 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 for the Ross Dependency.

This dataset only includes marks that are within Antarctica. These positions have been generated using geodetic observations such as precise differential GPS or electronic distance and theodolite angles 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.

Accuracy

Geodetic marks with a coordinate order of 5 or less have been positioned in terms of Ross Sea Region Geodetic Datum 2000 (RSRGD2000) using precise differential GPS techniques. Marks with order 6 have been positioned in terms of RSRGD2000 using precise horizontal angles and distance measurements. Lower order marks (order 7 and greater) are derived from lower accuracy measurement techniques or historical datum transformations, and may be significantly less accurate.

The accuracy of RSRGD2000 coordinates is described by a series of 'orders' classifications. Positions in terms of RSRGD2000 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.

This dataset was last updated on LINZ Data Service on 30 May 2020.

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 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 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.
