Hi,

I am using PostGIS functionalities especially on types LINE and 
MULTIPOLYGON.

According to OGC Simple Features for SQL definition, POLYGONS ans 
MULTIPOLYGONS have always lines. No curves (e.g. gml:Arc) are supported. 
The CURVE, SURFACE datatypes are not instantiable.

However ,I am also dealing with surfaces which have both lines and 
circular segments, in GML defined as Arc. So things become complicated 
as I need to deal also with these surfaces.

Is there a possibility to deal with arcs or circular segments in PostGIS 
although SimpleFeatures does not supprot that?

Regards,

Hubert Fröhlich
