A layer control tool for controlling the display of geographic data layers in a geographic information system is provided. The layer control tool can be presented in overlaying the geographic imagery. The layer control tool can include a plurality of identifiers associated with a set of geographic data layers that can be displayed in conjunction with the geographic imagery. A user can adjust or control the display of geographic data layers in conjunction with the geographic imagery by interacting with the floating layer control tool. For instance, a user can interact with the floating layer control tool, for instance by tapping a touch screen, to identify a selected geographic data layer in the set of geographic data layers. Responsive to this user interaction, the geographic information system can display the geographic data layer in conjunction with the geographic imagery and hide other previous displayed geographic data layers.
