Abstract: A client receives map objects that define respective physical objects of a floor plan of a building, including a floor plan outer boundary, one or more rooms, and connected pathways traversable by a person. The client renders, in scalable vector graphic form, the map objects into a map of the floor plan that depicts the respective physical objects, including the one or more rooms, the connected pathways, and the outer boundary. The client displays the map. The client receives an update message that defines a change to the floor plan with respect to a map object identified in the update message, and renders the change with respect to the identified map object into the map to depict the change on the map without rendering any other ones of the map objects that were previously rendered into the map. The client displays the map with the change depicted on the map.

Abstract translation: 客户端接收定义建筑物平面图的各个物理对象的地图对象，包括平面外边界，一个或多个房间以及人们可穿过的连接路径。 客户端以可缩放的矢量图形式将地图对象呈现为描绘各个物理对象（包括一个或多个房间，连接的路径和外边界）的平面图的地图。 客户端显示地图。 客户端接收到更新消息，其定义相对于在更新消息中标识的地图对象的平面图的改变，并且将相对于所识别的地图对象的改变呈现到地图中以描绘地图上的改变而不呈现任何 以前渲染到地图中的其他地图对象。 客户端显示地图上绘制的更改。
