Does anyone have special knowledge about Oracle Spatial?
I buffered polygons in Oracle-11 Database by making them slightly smaller (-50cm). The geometries are then delivered via a WFS as GML. With Oracle 11, I get not only simple closed rings as buffered polygons (last pair of coordinates equals first pair of coordinates, 1003: exterior polygon ring ), but also compound polygons made of LineStringSegments and arcs (1005: Compound polygon with some vertices connected by straight line segments and some by circular arcs).
This effect does not occur with Oracle 19 Database, all buffer geometries are simple closed rings (1003).
What do I have to do to achieve this in the Oracle 11 database as well?
