Two-dimensional Data Types
2D data types exist in a two-dimensional coordinate space represented by X (longitude) and Y (latitude) coordinates.
2D types include:
• Point
• Linestring
• Polygon
• GeometryCollection
• Multipoint
• MultiLinestring
• MultiPolygon
• PolyhedralSurface
• MultiCurve
• MultiSurface
• CircularString
• CompoundCurve
• CurvePolygon
• TIN
• Triangle
