A recent Supreme Court decision redefined the legal boundaries of California along the Pacific Ocean: http://www.theverge.com/tldr/2014/12/15/7397085/supreme-court-california-boundaries-map
I am confused how you would plot the points as they are described in the Supreme Court decision.
BEGINNING AT 482577.890 3599275.555
BY ARC CENTERED AT 488133.576 3599216.475
TO 482623.800 3599931.673
I am assuming these are bezier curves in a CAD system but I am not certain how to do this calculation in QGIS or OGR using a spatial reference system (EPSG:26910).
