Dynamic Building Extrusion in Electronic Maps

Techniques are described for building extrusion in an electronic map. A client map application receives geographic location information, such as from a user input. The client map application retrieves electronic map data representing a specific building at a location indicated by the received geographic location information. The client map application generates an extruded building graphical element illustrating the specific building in three dimensions based on the retrieved electronic map data representing the specific building. The client map application renders an electronic map representing electronic map data according to a first style. The electronic map also includes the extruded building graphical element such that the specific building is rendered in three dimensions according to a second style.
