[postgis-users] Representing an ellipse in PostGIS

[George Ryan]

Hello,

I am wondering what the best/most used approach to representing ellipses 
in PostGIS is. I have a point that has an elliptical measurement error 
boundary associated it, and I would be looking to calculate 
intersections with that ellipse. I figure there's probably a way to 
approximate an ellipse using a polygon, but I'm not sure if the 
performance of that for fine-grained detail would be good.

Thank you!
