Abstract: In one aspect, information of multiple anchor points is received and stored. The information of each anchor point includes Global Positioning System (GPS) data of a particular location and radio frequency (RF) data that was obtained at a device at the particular location. A geo coordinate is determined for an indoor location based on the RF data obtained at the indoor location and the information of the anchor points. Various embodiments pertain to software, systems, devices and methods relating to anchor points and/or the obtaining of a geo coordinate for a location.

Abstract: A technique to automatically determine a shape of a path based on crowdsourced trajectory data is disclosed. Trajectory data is collected for a plurality of crowdsourced paths. The trajectory data for each of the plurality of crowdsourced paths is associated with at least one uniquely identifiable ambient signal. Anchor points may be identified corresponding to a transition in a characteristic of trajectory data of an individual crowdsourced path. Matching may be performed based on analyzing matching patterns of anchor points and evaluating the matches. Various embodiments involve using a linked node structure to represent one or more traces and/or indicate routes in a particular geographical area.

Abstract: In one aspect, GPS data, ambient signal data, radio frequency data and/or other types of data are used to determine the location of an entrance to an area or a building. In another aspect, sequential trajectory data is collected and the data is analyzed and/or processed to determine the location of an area of interest.
