EPSG:22739 NAD83(CSRS)v7 / PEI Stereographic
Projected system (Oblique Stereographic) in use: Canada - Prince Edward Island. 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.
