6. A computer comprising: memory storing a database including a plurality of 3D models of objects, wherein each 3D model of an object of the plurality of 3D models of objects is associated with information defining a geographic area of a base polygon of the respective object, the memory also storing map information including a plurality of points of interest, where each point of interest of the plurality of points of interest is associated with a geographic coordinate; and a processor coupled to the memory and operable to: select a 3D model of an object from the plurality of 3D models of objects; determine whether the geographic coordinate of a given point of interest of the plurality of points of interest is within the geographic area of the base polygon defined by the information associated with the selected 3D model of the object; when the geographic coordinate of a given point of interest of the plurality of points of interest is within the geographic area of the base polygon defined by the information associated with the selected 3D model of the object, create a system tag including a search term selected based on the given point of interest; associate the system tag with the selected 3D model of an object; and store the association in the memory.
