Split Map View allows you to have two views of the Table Of Contents window and the map frame. Having another window that shows the layers and the map frame can help you perform visual quality control of data on the map. For example, you can load imagery and features collected and use the tools in the Split map View window to visually compare them and determine if features need to be added or edited.
