EPSG:6853 NAD83(CORS96) / Oregon Portland zone (ft)
Projected system (Lambert Conic Conformal (1SP)) in use: USA - Oregon - Portland. 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.
