To display web map data, use the
webmap function. By default,
webmap displays the World Street Map, centered at latitude and
longitude [0 0], but you select other base layers from the Layer Manager. Web maps are
interactive, which means you can navigate the map interactively by using the pan and
zoom controls, your mouse, or the arrow keys. By default, you can pan across the map
continuously, across the 180 meridian.
