At 42.5 Latitude what degree is north to match up to property boundaries? Doing geometry, I think it is about 359.5 at 1 mile away from the meridian. I think it is about 45 ft for one mile north/south and for each mile off of the meridian. I want to set all my fields at the same angle for consistency and match up to roads and property lines. Are all State meridians true north? GPS is fixed as true north and not magnetic north. Assuming counties and states are plotted as square, then the farther away from the meridian the higher the difference from true north. East/west fields are not a problem as latitude lines are parallel where longitudinal lines are not parallel.
