Reference Elevation Model of Antarctica version 2, 100 metre contours

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.
