I'm using PostGIS 2.0.0 and would like to store a GML Surface in a way
that allows calculating intersections between that surface and various
points and lines. In my case, the Surface will have one PolygonPatch
with no interior rings and an exterior ring which may be a
LineStringSegment, a Geodesic, an Arc or a Circle. The distances can be
in the order of tens to hundreds of miles.
CIRCULARSTRING and CURVEPOLYGON would seem like a good way of storing an
Arc, except that they're not supported by the geography type, only
geometry. Are there any plans to add support for them any time soon?
What would be the best approach to this in the meanwhile?
Regards,
Evan Martin
