There is following polygon: POLYGON((317371.62563763 5731575.49932608, 317028.110300846 5731043.43103426, 317028.110300846 5731043.43103426, 316389.822682815 5731138.79331604, 316478.209591618 5731705.00321977, 316478.209591619 5731705.00321977, 317350.223258488 5731584.46661525, 317371.62563763 5731575.49932608))
with two duplicate nodes. When I try to check it with ST_IsValidReason function I get message that it is Valid Geometry. Is this OGC compliant? When I try to check it with QGIS, ArcView or ArcGIS - I get notice about self intersection. Please explain this situation. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
