Abstract
A map data server may provide metadata about available indoor map data that accompanies map data for drawing a base map. For example, map data may include vector data for drawing a footprint of a building, and the metadata may include information about the physical properties of the building (e.g., an indication of how many floors the building has and if detailed map data is available for the indicated floors, etc.). A mapping application running on the client can use this metadata to display an interface that allows a user to select floors or otherwise interact with the floor data. Further, the metadata accompanying map data can include a bounding box, or a bounding polygon, for one or more floors. The mapping application can use these bounding shapes to properly reposition the viewport as map data for a new floor is being loaded, for example.
