"Points of a LinearRing do not form a closed linestring" on polygon touching
south pole
---------------------------------------------------------------------------------------
Key: GEOS-4866
URL: https://jira.codehaus.org/browse/GEOS-4866
Project: GeoServer
Issue Type: Bug
Affects Versions: 2.1.2
Environment: Windows 7 x64, PostgreSQL 9.1.1, PostGIS 2.0.0, JVM
1.6.0_29
Reporter: Evan Martin
Assignee: Andrea Aime
When previewing some polygons read from a PostGIS 2.0.0 database using
OpenLayers GeoServer displays the following error:
code="internalError" Rendering process failed
Points of a LinearRing do not form a closed linestring
It doesn't specify which polygon caused the problem (so that would be nice to
fix, too), but by trial an error I've found one that reproduces it:
SRID=4326;MULTIPOLYGON(((-131 -73.5,0 -90,163 -60,174 -60,-131 -73.5)))
Zooming in one level gets rid of the error and the polygon is displayed.
Clearly, it is closed, otherwise PostGIS would not even allow it to be inserted
into the DB. I suspect it may be related to the polygon touching the South pole.
