Multi-dimensional trajectory analysis and visualization method and device based on spatio-temporal data

The invention discloses a multi-dimensional trajectory analysis and visualization method and device based on spatio-temporal data, and the method comprises the steps: obtaining a spatio-temporal data source of a historical time period and a spatial position, and responding to the determination that the spatio-temporal data source comprises at least one target feature value; the target feature values comprise feature values of different objects with corresponding time attributes and space attributes, filtering and sorting the spatio-temporal data source to obtain an ordered number column, and the ordered number column is at least one piece of trajectory data; processing the ordered sequence according to different trajectory analysis dimensions to obtain a first data matrix under different dimensions; filtering the first data matrix based on the target time period to obtain a second data matrix; and the second data matrix is combined with the map and the web visual data to carry out point location display, trac
