  The storage, management, and application of massive spatio-temporal data are
widely applied in various practical scenarios, including public safety.
However, due to the unique spatio-temporal distribution characteristics of
re-al-world data, most existing methods have limitations in terms of the
spatio-temporal proximity of data and load balancing in distributed storage.
There-fore, this paper proposes an efficient partitioning method of large-scale
public safety spatio-temporal data based on information loss constraints
(IFL-LSTP). The IFL-LSTP model specifically targets large-scale spatio-temporal
point da-ta by combining the spatio-temporal partitioning module (STPM) with
the graph partitioning module (GPM). This approach can significantly reduce the
scale of data while maintaining the model's accuracy, in order to improve the
partitioning efficiency. It can also ensure the load balancing of distributed
storage while maintaining spatio-temporal proximity of the data partitioning
results. This method provides a new solution for distributed storage of
mas-sive spatio-temporal data. The experimental results on multiple real-world
da-tasets demonstrate the effectiveness and superiority of IFL-LSTP.
