EPSG:3411 NSIDC Sea Ice Polar Stereographic North
Projected system (Polar Stereographic (variant B)) in use: World - N hemisphere - north of 60°N. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
