Full description

This dataset consists of 100-metre-interval contour lines across East Antarctica. The contours are derived from the REMA 2 (Reference Elevation Model of Antarctica version 2) 10-metre mosaic digital elevation model. Features were produced using the ArcGIS Pro 'Generate Topographic Contours' tool with a Raster Smooth Tolerance of 0.6, a Contour Minimum Length of 300 metres, and a Contour Smooth Tolerance of 150 metres based on an output map scale of 1:1 million. Contour generation was limited to a source mosaic tile set extending from the from approximately 31°E to 177°E and from the coast inland to approximately 76°S. The contours were edited to remove holes present in the source DEM and some shorter-length contours were manually removed to improve clarity. This data is stored in the AAD's relief ln enterprise dataset.

Lineage

Progress Code: completed
Statement: A small number of holes (null value raster cells) in the source dataset produced contour aberrations that had to be manually edited. The dates provided in temporal coverage refer to the collection period of the source data.

Notes

Purpose
These contours were produced for use in the Australian Antarctic Division’s 1:1,000,000 Topographic Map series (2022).

Data time period: 2009-01-01 to 2021-12-31
