MAP LENS IN A USER INTERFACE

A map lens may take the form of a shape that may be superimposed on a map displayed in the user interface, moved around the map by the user, and activated by the user to select a region of the map bounded by the map lens. Activation of the map lens may cause the user interface to display only those markers that are within the region bounded by the map lens. In situations where the user moves the map lens over unselected regions of the map, the user interface may dynamically show or hide markers on the map. This may have the effect of presenting to the user a visually uncluttered map in which markers are only shown in the region in which the user has expressed some interest, as indicated by the user moving the map lens to that region of the map.
