The invention relates to a method for processing a set of data collected by at least one sensor at successive points in the travel over a plot of land (1) of at least one vehicle (2), each piece of said data having been recorded with a time delay with respect to the time at which the vehicle passes a given point of the plot, that is to say representing an item of information relating to the state of the vehicle at a time earlier than the recording time of said data, each piece of data being associated with a recording time and a geographic position of a point known as a measuring point at this recording time, and being provided by geolocation means. The method comprises a phase of estimating an optimal delay value by minimizing a level of projection of a three-dimensional map of values measured at each geographic point, and of correcting the measured data by this delay.
