Ticket #512 (new enhancement)
Use prepared geometries for relate-pattern tests
|Reported by:||cdestigter||Owned by:||strk|
We recently changed a postgis query from ST_Intersects(a, b) to ST_Relate(a, b, 'T********') and were surprised to note a massive performance decrease for large geometries.
Turns out GEOS (and JTS) don't yet support using prepared geometries for the relate-pattern predicate.
Is this hard to add? Does the fact that it's not in JTS preclude it from being added to GEOS?
If not, I'd consider writing a patch, but I could use some direction since this would be my first significant contribution to GEOS.
