Dynamic Building Extrusion in Electronic Maps

A system or a method for rendering building extrusion on an electronic map. The system receives geographic location information from a client device. Responsive to receiving the geographic location information, the system obtains a portion of two-dimensional electronic map data and a portion of three-dimensional electronic map data representing a building at a location indicated by the received geographic location information. The system also analyzes user data to obtain contextual information associated with the building, and renders the area of the electronic map with the contextual information associated with the building. The building on the electronic map is rendered in three dimensions as an extruded element, and rest of the area on the electronic map is rendered in two dimensions.
