Healing a radio map

A system comprising:

• one or more processors;
• and
• at least one non-transitory device storing computing instructions operable to cause the one or more processors to perform operations comprising:
• receiving a harvest trace from a mobile device, the harvest trace including a plurality of location fixes each corresponding to a location of a venue, each location fix associated with data including RSSI measurements of wireless signals received from each of a first plurality of wireless access points positioned at the venue, the plurality of location fixes including at least two location fixes that have a positional relationship with each other;
• comparing the data associated with one of the location fixes with data associated with a reference point identified in a radio map of the venue, the data associated with the reference point includes RSSI measurements of wireless signals received from each of a second plurality of wireless access points;
• based upon the comparing, determining that one or more of the first plurality of wireless access points are absent from the second plurality of wireless access points;
• updating the data associated with the reference point to include the RSSI measurements of the wireless signals received from the one or more absent wireless access points;
• identifying an additional reference point located above or below the reference point on a different floor of the venue that correspond to the reference point;
• updating data associated with the additional reference point to include the RSSI measurements of the wireless signals received from the one or more absent wireless access points;
• and
• updating the radio map of the venue based on the updated data associated with the reference point.
