1. A method comprising: identifying, by one or more computing devices, a 3D model of an object from 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; determining, by the one or more computing devices, whether a geographic coordinate of a point of interest is within the geographic area of the base polygon; when the geographic coordinate of the point of interest is within the geographic area of the base polygon, creating, by the one or more computing devices, a system tag including a search term selected based on the given point of interest; and associating, by the one or more computing devices, the system tag with the identified 3D model of the object.
