The following bug has been logged online: Bug reference: 4967 Logged by: Paul Matthews Email address: p...@netspace.net.au PostgreSQL version: 8.3.7 Operating system: Linux Open Suse 11.0 + 11.1 Description: polygon @> point incorrect for points close to shared borders Details:
Have two polygons, both with many vertex, sharing a common edge. Several thousand points where then tested to see which of the polygons the points fell into using the "polygon @> point" operator. A number of points close to the common border claimed they fell into both of the polygons. A quick perl+DBI+GD application was developed to plot both the polygons, the polygon boundaries, as well as the points that thought they where in both. This showed points close, but still several pixels away from the shared border, thinking they where in both. Guidance on this matter would be appreciated. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
