huge compass rose

Located near NASA's Dryden Flight Research Center in California, this huge compass rose is 1.21km in diameter. It is inclined to magnetic north (around 13 degrees east of true north) and is used by pilots for calibrating heading indicators. It is painted onto the Rogers and Rosamond dry lake beds, which are available for emergency and scheduled landing sites for many aerospace projects.

Check it out from Google maps.
