NZ Ross Dependency Contours (ANT, 1:50k)
An imaginary line that connects points of equal height value eg the elevation of the land surface above or below a vertical datum, in this case of LINZ topographic mapping, this is Mean Sea Level.

- Purpose
- Ant50 is the topographic mapping carried out by LINZ within the Ross Dependency, Antarctica. Permits may be required to visit some sensitive and special islands and areas. When using Ant50 data, please be aware of the following: 1. Due to lack of contrast in some source images, no feature capture was able to take place on some of the glacier regions 2. Mapping of different areas of the Dry Valleys and Ross Island was undertaken in the 1980s and 1990s. At this time, metadata for the source images of each area of mapping is not available 3. Contours and spot elevations in snow areas may be less accurate 4. The location of tracks on sea ice is subject to annual change 5. The existance of a road or track does not necessarily indicate permitted access 6. Ice shelf and sea extents are from differring data sources and dates 7. Absence of crevasse data does not necessarily indicate a crevasse-free area

- Statement
- Since 1923, New Zealand has maintained its right of sovereignty over the Ross Dependency, an area defined as all islands and territories south of 60 degrees south latitude and between the 160th degree of east longitude and the 150th degree of west longitude. LINZ, in conjunction with the USGS, carried out mapping of the Dry Valleys area and Ross Island in the 1980s and 1990s. In 2007, LINZ expanded the mapping to include the Darwin/Hatherton Glacier region of Antarctica. The purpose of this is to support science taking place in the region as part of the Latitudinal Gradient Project. The data provided is based on ALOS PRISM satellite imagery taken during the 2006/07 season and is supplied in the Darwin Glacier Lambert Conformal Conic 2000 projection. The survey work for this data was undertaken between 2007-2010.
