Hi Salas, are "interior parcels" islands ? ST_NumInteriorRings(geometry)
Return the number of interior rings of the first polygon in the geometry. Return NULL if there is no polygon in the geometry. ST_NumInteriorRing(geometry) Synonym to NumInteriorRings(geometry). The OpenGIS specs are ambiguous about the exact function naming, so we provide both spellings. ST_InteriorRingN(geometry,integer) Return the N'th interior ring of the polygon geometry. Return NULL if the geometry is not a polygon or the given N is out of range. Fred.
