[postgis-users] Representing this polygon.

[Paul Ramsey]

Theoretically, with a CURVEPOLYGON. Practically, by stroking that arc
so it's a standard POLYGON.

ST_Union(
ST_Transform(ST_Buffer(ST_Transform(ST_GeomFromText('POINT(-115.79222222
49.955)', 4269),26910),50*1609),4269),
ST_GeomFromText('POLYGON((-123.25 56, -119 53.4, -116.-8472222
50.32638888, -115.79222222 49.955, -115.14722222 49.9625, -115.1375
49.5, -115.49972222 49.00055555, 123.25 56))',4269)
)

I hate DMS notation, I hate it so...
