Embodiment 1
[0099] A method for determining an associated co-occurrence mode of a moving target, the specific steps are:
[0100] Step 1. Divide the activity data of the moving target to obtain an activity data set, and the specific division method is as follows:
[0101] Divide the active area of the moving target by latitude and longitude to obtain the active area data set:
[0102] Area={a 1 ,a 2 ,…,a area }
[0103] In the formula, area is the total number of divided areas;
[0104] Example 1 The divided areas are shown in Table 1.
[0105] Table 1 Division area table
[0106] Aid area name center longitude central latitude 1 a 113.9333334 13.43333333 2 b 112.8836 9.569861 3 c 114.06 10.91361 4 d 115.53833 9.901667 5 e 112.83111 8.865 6 f 114.467721 9.910278 7 g 114.5586646 9.905833334 8 h 114.2811111 8.742083334
