Geometries

There are three types of geometry within 1Integrate: points, lines and areas.

Each can be defined in terms of its dimensions, and if it has an interior, exterior and boundary.

Geometry	Dimensions	Interior	Exterior	Boundary	Description
Point	0				A point is a 0-dimensional geometry that has an interior and an exterior, but no boundary.
Line	1				A line is a 1-dimensional geometry that has an interior, an exterior, and a boundary.
					If the line is a closed ring, there is no boundary (as the boundary is at the end points of a line).
Area	2				An area is a 2-dimensional geometry that has an interior, an exterior, and a boundary.

Note: For multi-part geometries, the interior or boundary is the union of the interiors or boundaries of all parts.
