For SDS arrays with more than three dimensions, users have to choose three dimensions among the multiple dimensions of the data. JHV provides two ways of subseting, mouse drag and typing in. Draging the mouse on the preview image sets the values of the starting and ending coordinates of the horizontal and vertical axis. You can also select a target dimension in the selection window and type in the values of the starting and ending coordinates of that dimension. If the image is very large, the initial display will sub-sample the image and display a thumbnail.
Users can zoom in and out the preview image in the selection window.
The View menu provides four window viewing options and three image viewing options. The window options allow users to hide or show JHV subwindows. The image viewing options include Default , Animation , and Layer . Animation and Layer can be used to view multiple raster images in animation or layer. The use of these options is discussed in Chapter 7, Animation , and Chapter 8, Image Overlays .
