In this section:
The View tab is the main data display mechanism for the data access client and acts as a visual data browser. Users would normally search for data of interest using the Catalog tab, then switch to the View tab to view data of interest interactively. For convenience, the data access client starts up with the View tab selected and displaying the most current data from the first dataset. Users can modify the data view by using the tool bar buttons, the date/time selector, and by clicking and dragging on the data view itself.
The following figure shows the main components of the client when the View tab is selected:
