1. A computer-implemented method of analyzing geospatial trajectories, comprising:

  • in response to a user event from an end-user device, generating a grid model of a geographical area of interest by a server, wherein the grid model comprises a grid having a plurality of rows and columns of cells, wherein the cells are identified by unique cell numbers;

    mapping geospatial trajectory data of users to the cells in the grid by the server, the geospatial trajectory data comprises 2-dimensional spatial-temporal data with longitude and latitude information related to trajectory of the users, wherein mapping the trajectory data generates mapped data with unique cell numbers associated to the geospatial trajectory data;

    analyzing the mapped geospatial trajectory data to identify cell transitions based on the mapped data, wherein identifying the cell transitions comprisesdetermining cell density sequences of the users, anddetermining cell dwell-time sequences of the users;

    analyzing the cell density and cell dwell-time sequences to perform a similarity analysis; and

    presenting results of the similarity analysis to the end-user device of a user.
