All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

Contours for the Amery Region map published by the Australian Antarctic Data Centre in November 2002 (see link below).
This contour data were derived from Russian space photography, ERS-1 and ERS-2 Radar altimeter data (BKG, Germany) and the Antarctic Digital Database, Version 2. Refer to the contour source diagram - digital data (refer to metadata record ERS_CONT_SOURCE_AMERY) or view map (see link below). The contour interval is 500 metres from 500 to 3000 metres. There are also 200 metre contours.

ESA's two European Remote Sensing (ERS) satellites, ERS-1 and 2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.

ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.

The ERS-1 mission ended on 10 March 2000 and ERS-2 was retired on 05 September 2011.

Quality

This data set was derived from a number of different sources to produce contours for the Amery Region map published by the Australian Antarctic Data Centre in November 2002.
The data set consists of contours derived from ERS radar altimetry (refer to metadata record ERS_CONT_500_ANT), the Antarctic Digital Database Version 2 and Russian space photography.
All contours with elevations of 1500 metres and above are from ERS radar altimetry while these were only used at lower altitudes where contours from the other two data sources were not available.
Where contours from two different sources did not join, new contours were placed visually and assigned a certainty value of connector to create a smooth transition from one dataset to the other.
Contours range from 500 metres to 3000 metres on a 500 metre interval. There are also 200 metre contours.
