To solve the problem of big data storing of aerial target trace, this paper proposes a point track screening method based on rule base in data screening process. For information compression on point track elements, the paper puts forward the compression algorithm of the run-length coding of the point track information, sequeutial coding and fixed bit length coding based on big data column storage. For the information compression of track position, an improved adaptive fitting compression algorithm is suggested. Comparative analysis and experimental results show that the proposed method can greatly reduce the storage space for the aerial target point track data, and make a data preparation for big data mining and analysis of aerial target.
