Point Overview

Geometric Data (Points)

Geometric co-ordinate points in Oracle spatial can be 2d, 3d or even 4d. These can be representative of anything like a building or location.

Points can also be oriented to show direction and can also be 2d, 3d or 4d. They are usually used to show vector information and orientation. This is purely for display purposes, the point does not move.

A simple point is represented by (x,y) and an oriented point by (x,y,x1,y1).

If you track a car around a maze you can plot the position every five seconds and get a breadcrumb like trail of points. If you add on orientation you can see direction of travel from a single point.
