* Ein planarer linearer Ring <math>R_s</math> definiert den Rand eines Polygons <math>S</math> (äußerer Ring).

* A Polygon <math>S</math> is defined by a planar Linear Ring  <math>R_s</math> (exterior ring).

* Ein Polygon ist durch genau einen solchen äußeren Ring und <math>n\ge0</math> innere Ringe definiert. Jeder innere lineare Ring muss ebenfalls planar sein, und der äußere und alle inneren linearen Ringe müssen in derselben Ebene (im Rahmen einer gegebenen Toleranz) liegen.

* A polygon has exactly one exterior ring. In addition, a polygon can have <math>n\ge0</math> interior rings. These interior rings a planar Linear Rings as well. All interior rings and the exterior ring must be on the same plane (within the given tolerance).  

* Jeder '''innere''' lineare Ring '''muss innerhalb des Gebiets''' der Ebene liegen, das der '''äußere''' Ring begrenzt.

* As interior rings define holes in the polygon, they have to be completely included in the area defined by the exterior ring. Interior rings must not overlap other Linear Rings or be included in another Linear Ring (except the exterior Linear Ring). <table width="900px"  border="0" cellspacing="0">
