Such as the design of global navigation or aviation routes, cross-field measurements of the distance between the eastern and western hemispheres. Click the Pan drop-down button in the Browse group of the Map tab and select the Global Pan option to turn on the feature.
Global Pan has some requirements for the map of reference coordinate system. There are currently two types of coordinate systems that support global pan: WGS 1984 and World Mercator.
