EPSG:6841 NAD83(CORS96) / Oregon Coast zone (ft)
Projected system (Hotine Oblique Mercator (variant A)) in use: USA - Oregon - Oregon Coast. 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.
