Dynamic building extrusion in electronic maps

A non-transitory computer-readable storage medium storing computer program instructions, when executed by one or more processors, cause the one or more processors to:

• access an electronic map comprising two-dimensional and three-dimensional electronic map data;
• receive geographic location information from a client device;
• responsive to receiving the geographic location information, obtain a portion of the two-dimensional electronic map data representing an area associated with the geographic location information, and a portion of the three-dimensional electronic map data representing a building at a location indicated by the received geographic location information;
• analyze user data to obtain contextual information associated with the building, wherein contextual information comprises a calendar item specifying an appointment and a building where the appointment is scheduled to occur;
• and
• render the area of the electronic map with the contextual information associated with the building, wherein the building on the electronic map is rendered in three dimensions as an extruded element annotated with the contextual information, and rest of the area on the electronic map is rendered in two dimensions.
