摘要： A rule set is used to generate an indoor map of a building from partial map data. In one embodiment, the partial map data is based at least in part on crowd sourced trajectory data. In one embodiment, a probabilistic rule set describes relationships in space usage of the indoor building. Hypothesis testing is performed. A most likely complete layout is determined, based on the partial coverage data and the rule set, which preserves the partial map data.

摘要： In one aspect, a method for determining a location of a landmark using a map is described. Trajectory data is obtained indicating movement of a device at an area. The trajectory data indicates a landmark. A map is obtained of the area. At least a portion of the trajectory data is compared and/or matched with at least a portion of the map. Based on the matching, a location of the landmark is determined in the map. Various implementations involve system, devices and software relating to the above method.
