&nbsp;A escala muda automaticamente quando é aplicado o "zoom in" ou "zoom out" (zoom de aumento ou de redução).
&nbsp;Esta comparação pode ser muito melhor unido-se as viewers. Para isso vá ao primeiro Viewer e selecione "View" &gt; "Link/Unlink Viewers" &gt; "Geographical". Seguindo as instruções, clique no segundo Viewer. A extensão da área no "Viewer #2" é imediatamente marcada no "Viewer #1". Para movimentar a caixa, utilize o mouse, clique e arraste os  braços que circundam a caixa. Para redimensionar e, portanto ter outra visualização, use o mouse, clique e arraste a caixa.
