The Map Viewer can be duplicated or cloned in order to provide several views of the dataset for comparison purposes. This can be useful to look at the same area during two different time periods, or the same time period with different thematic classifications. To duplicate the Map Viewer click on the "Duplicate the Map Viewer" button from the Map Viewer tool bar.

The newly created Map Viewer will have the same legend and same initial extent as the original Map Viewer. Cloned Map Viewers do not have all of the simulation control buttons, and closing a duplicated Map Viewer does not end the simulation.
