SPACEJUMP

This method is similar to the TEXTSEARCH method, but instead of the search criterion being a text string, it is a set of coordinates defining a point within the image. The semantics of the operation are not defined here. Typically, the user clicks on a point within the image with a mouse or other pointing device.

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 .
