invalid donut polygon
---------------------
Key: GEOT-3664
URL: https://jira.codehaus.org/browse/GEOT-3664
Project: GeoTools
Issue Type: Bug
Components: arcsde plugin
Affects Versions: 8.0-M0
Reporter: Rudi Hochmeister
Assignee: Gabriel Roldán
Attachments: correctDonut.xml, Donut-Polygon.JPG, incorrectDonut.xml
ArcSDE JAVA API 9.3 cannot correctly handle Donut Polygons where shell shares a
single vertex with a hole (which is a valid geometry as of JTS). If so, then
the hole does not get recognized
and vertices of hole are added to shell, which results in an invalid geometry.
It seems the problem only occurs when getting geometry out of geo-db and
building such a donut from a SeShape.
Persisting a donut geometry in geodatabase seems to be ok.
correctDonut.xml shows what the geometry (which has been persisted to geo-db)
should look like in a GetFeature Response
incorrectDonut.xml shows the invalid geometry in GetFeature Response
donut-polygon.jpg shows the donut polygon which shares a single vertex with
between shell and hole.
