Two or more coordinates are supplied, in the order x, y z, t. All coordinates are scaled so that 0 represents the bottom left hand point and 1.0 represents the top right hand point.
The z access direction follows the normal right-hand rule, that is extends toward the viewer when the x and y axes are flat as in the normal two-dimensional representation.
In the case of a time-occupying object, 0 represents the starting instance, and 1.0 represents the finishing instant.
The method is implemented using GET with a derived URL .
