A system for cross verification of data captured by a consumer electronic device is disclosed. Primary data, for example, a photograph, is captured by a mobile capture device, metadata including the time and location of the capture is associated with the primary data. Environmental data, for example, pressure, temperature, visible WiFi networks, visible cell towers, is also measure by the mobile capture device. Other capture devices are identified in the vicinity and those other devices also measure environmental data. The measurements of environmental data can then be compared in order to calculate a confidence level in the position metadata associated with the primary data.
