> by client > World Wind

  Use case: All possible 2-D slices from x/y/t image timeseries climate_temperature. Climate researchers want to obtain 2-D slices from 3-D x/y/t climate simulation output. For this demo, a 3-D x/y/t data set is used. A 3-D visualization client allows to inspect the data set. This so-called ortho slicing utility represents the cube as three orthogonal slices. By adjusting the slider and clicking on the retrieve button the slice at a certain position in time can be viewed. The particular advantage of such a viewer is that not the whole (large) cube needs to be transported over the networks, but only the selected slices (which usually are comparatively small). Only when the user selects another slicing position, new slices need to be fetched. This way, the user can inspect data with a much better interactive experience.

  The Service: The following Use Cases are being presented below. Select a time slice using the slider and press on retrieve to display it on the globe. You can also click on the Run timelapse button to see a time lapse of the slices.
