[postgis-users] Intersection of LineStrings

[Ed Linde]

Hi All,
Simple question. I have a table with half a million linestring geometries,
and I want to compute the
intersection points and also the linestring pairs that intersect with each
other.
How can I do this? Is there an index that can avoid having to do a
self-join and computing
the intersections?

Cheers,
Ed
