This invention relates to distributed single integrated picture method, platform and network for tracking moving objects. More particularly, this invention is adapted to create and maintain a Single Integrated Air Picture (SIAP) by each platform in the distributed network. <??>An object of this invention is a data compression method adapted for tracking system comprising : the reception of locally acquired data, the prediction of trajectory from these locally acquired data, the calculation of short tracks from these locally predicted trajectories, a dynamical reduction of the short track calculation and/or distribution. The dynamical reduction could comprise an update of the short tracks only if predicted trajectory deviates from a predetermined value from an estimated local trajectory or if predicted trajectory accuracy becomes larger than a predetermined accuracy threshold. <??>The data compression method influences the timely availability of the Single Integrated Air Picture (SIAP), and thereby the maintenance of Single Integrated Air Picture (SIAP). <IMAGE>
