Please note: The LCRA uses a conic projection as its mapping standard. 0 10 20 Miles Map location Because of this, the GPS grid on this map appears to be rotated slightly counterclockwise. This occurs because the location is east of the 30º 56.00' using GPS reading projection’s central meridian. Note how much closer the meridians 410 are to each other than the parallels are. This is a relatively accurate 411 reflection of actual distance between these lines. The coordinates -98º 6.00' -98º 5.00' -98º 4.00' -98º 3.00' shown are based on the GRS 80 spheroid (NAD83 Datum).
