1. A method of correcting a time lag for a set of data, comprising the steps of: generating a plurality of adjusted data sets by replacing geographic coordinates of a measuring point supplied by a geolocation system with geographic coordinates of a previous or a future measuring point having a time lag value to shift the geographic coordinates of the measuring point; and for each set of adjusted data: building a three-dimensional map showing latitudes, longitudes and heights along the X, Y and Z axes, respectively, in accordance with the adjusted data associated with the measuring point, wherein a height represents a sensor value; determining a measurement of a developed surface area of the three-dimensional map; calculating a surface area of a projection of the three-dimensional map onto a plane of latitudes and longitudes; calculating a projection ratio between the developed surface area of the three-dimensional map and the area of projection; determining a minimum value of the projection ratio for the sets of adjusted data; and correcting the set of data using the minimum value.
