Concepts

Code	Display	Definition
point	POINT	A single location denoted by a single (x,y) pair.
polyline	POLYLINE	A series of connected line segments with ordered vertices denoted by (x,y) triplets; if the first and last vertices are the same it is a closed polygon.
multipoint	MULTIPOINT	Multiple pixels each denoted by a (x,y) pair.
circle	CIRCLE	Two points shall be present; the first point is to be interpreted as the center and the second point as a point on the circumference of a circle, some form of implementation dependent representation of which is to be drawn.
ellipse	ELLIPSE	An ellipse defined by four (x,y) pairs, the first two pairs specifying the endpoints of the major axis and the second two pairs specifying the endpoints of the minor axis.
