Geometry Objects

MgGeometry is the base class for all the geometry types. The simple geometry types are:

• MgPoint — a single point
• MgLineString — a series of connected line segments
• MgCurveString — a series of connected curve segments
• MgPolygon — a polygon with sides formed from line segments
• MgCurvePolygon — a polygon with sides formed from curve segments

The curve segments are circular arcs, defined by a start point, an end point, and a control point.

Complex types are formed by aggregating simple types. The complex types are:

• MgMultiPoint — a group of points
• MgMultiLineString — a group of line strings
• MgMultiCurveString — a group of curve strings
• MgMultiPolygon — a group of polygons
• MgMultiCurvePolygon — a group of curve polygons
• MgMultiGeometry — a group of simple geometry objects of any type
