#845: ST_Intersects() precision error - returns false instead of true
------------------------+---------------------------------------------------
Reporter: cdestigter | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 2.0.0
Component: postgis | Version: 1.5.X
Keywords: |
------------------------+---------------------------------------------------
Comment(by strk):
Yes, within and contains (and intersects) all have a short-circuit using
the postgis algorithm when one operand is a polygon (or multipolygon) and
the other is a point.
Given the fact the same operations would use PreparedGeometries I'm
wondering
if that shortcut has any real advantage... After all the same operation
against
prepared geometries should be faster (as the prepared polygon would be
indexed).
