EPSG:2985 Petrels 1972 / Terre Adelie Polar Stereographic

Projected system (Polar Stereographic (variant C)) in use: Antarctica - Adelie Land - Petrels island. The full definition below, and conversion in one click.

PROJ — the reference library behind QGIS, GDAL and PostGIS — does not compute this method either: the page stays a reference and the system is not offered for conversion.
