According to one embodiment of the invention, a method for displaying graphical objects on a digital map includes receiving, for a graphical object, metadata comprising a parameter indicating a type of the graphical object, a parameter indicating a size of the graphical object, and a group of parameters indicating a geographic location of the object represented by the graphical object. The type of the graphical object is one of a group of stored types. The method further includes rendering the graphical object on the digital map by generating, based the received metadata, a group of geographic coordinates for the graphical object.
