Antarctic Topographic Data
LINZ is currently producing vector topographic data at 1:50,000 scale for 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. At present, this is the only Antarctic topographic data that is being provided by LINZ online. You can also download Antarctic geo-referenced orthophotos.
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.
Downloads for specific areas
To download the data for a specific sheet, select the area you are interested in. Only the areas covered by the satellite image (the polygon shape) contain data.
Please note that due to lack of contrast in the source images, no feature capture was able to take place on some of the glacier regions. The areas of these holes are available in this shapefile (zip 53KB).
