EPSG:3410 NSIDC EASE-Grid Global
Projected system (Lambert Cylindrical Equal Area (Spherical)) in use: World - 86°S to 86°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.
