Indicating the coordinate system in which it is embedded. If it has both Z and M the coordinate dimension is 4D. If a geometry has Z or M ordinates the coordinate dimension is 3D If Z or M values are present in a geometry value, they must be defined for each point in the geometry. ![]() The M ordinate contains a measure value, which may represent time or distance. The Z ordinate is often used to represent elevation. Shapes are constructed from points or line segments, with points specified by a single coordinate,Ĭoordinates may contain optional Z and M ordinate values. The size and location of shapes are specified by their coordinates.Įach coordinate has a X and Y ordinate value determining its location in the plane. The PolyhedralSurface, Triangle, and TIN types can also represent shapes in 3-dimensional space. Geometry models shapes in the 2-dimensional Cartesian plane. The Simple Features Access - Part 1: Common architecture v1.2.1 Which represent various kinds and dimensions of geometric shapes.

In Europe, the luxury sports model was available as a 120 hp (89 kW) direct injection turbodiesel ("DITD") estate up until 2007. The first generation was marketed as a 2003 model in the United States and as a 2004 model in Canada. In New Zealand, the lineup consisted of 2.0L GLX (sedan only), 2.3L GSX (sedan, liftback, and wagon), and 2.3L Limited (sedan and liftback). In Australia, the lineup was first available in Limited trim, as a sedan in Classic trim as sedan, hatch or wagon and in Luxury trim as a sedan and liftback - and Luxury Sports trim, as a liftback. The model lineup consisted of a four-door sedan, a four-door hatchback and a five-door wagon, marketed in North America as the "Sport Sedan", "5-Door" and "Sport Wagon", respectively. ![]() The first-generation Mazda6 was launched in Japan as the Mazda Atenza in May 2002. |
