[postgis-users] Creating an ellipse area ?

[Flavio Perri]

Hi, I tried that function, and seems to work fine, but I don't understand
the last parameter (i tried with 1000). Then, a question: I tried to select
all geometries inside the ellipse area with this query:
  select * from pointTable a, linesTable b where id=xxx and
Intersects(b.the_geom, ellipse(X(a.the_geom),Y(a.the_geom),0.010,0.005,
a.direction, 1000) and a.the_geom && l.the_geom

is it right?
