The DArk Matter Particle Explorer (DAMPE) can operate properly while crossing the South Atlantic Anomaly (SAA). Due to the high flux of cosmic rays in the SAA, the collected data within SAA are not used for most scientific analysis. Based on the data from DAMPE, we improve the definition of SAA with more precise determination of the boundary. We found that about 30% time in the pre-defined SAA period can be saved for normal data taking comparing with a typical polygon defined by the space weather forecast before launch.
