| Abstract: | The order topology of an ordered projective plane leads to a topological projective plane in which intersection and joining are continuous operations (c.f. O.WYLER 5]).Here continuity properties in projective planes with half order topology derived from a  SPERNER'sche Ordnungsfunktion are analysed. Central projections are continuous and planes which are connected with respect to the half order topology are (fully) ordered and therefore topological planes.
