EPSG:10266 KK reconstruction east-orientated

Projected system (Lambert Conic Conformal (1SP variant B)) in use: Denmark - Copenhagen. 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.
