EPSG:6821 NAD83(CORS96) / Oregon Eugene zone (ft)
Projected system (Transverse Mercator) in use: USA - Oregon - Eugene. 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.
