Abstract (en)
[origin: WO2006015188A2] Methods and apparatus for improving the accuracy and reach of electronic media exposure measurement systems are disclosed. A disclosed method includes processing data representative of locations recorded by an electronic device to enhance at least one of completeness or accuracy of the data, deriving position fixes from the processed data, and modifying at least one of the derived position fixes to align with a known course of travel.
