PROVIDING INDOOR MAP DATA TO A CLIENT COMPUTING DEVICE

摘要

A map data server may provide map data to a client device by generating a description of a geographic area that includes outdoor map features including a multi-story building. The multi-story building includes a "default" floor. The map data server may also provide data to the client device to graphically represent the indoor features of the default floor in the description of the geographic area. The indoor map features may be annotated to allow the client device to selectively activate or deactivate the display of the indoor map features.
