Embodiment Construction
[0049] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0050] like figure 1 As shown in , a statistical method for the area of spatial data in a custom range based on the grid spatial index, the specific steps are as follows:
[0051] Step 1: The server side establishes a global grid subdivision model based on the dichotomy rule of the Cartesian coordinate system, encodes the spatial data after iterative bisection, and establishes a spatial grid index.
[0052] The establishment process of the global grid subdivision model is as follows:
[0053] Step 1.1: Based on the Cartesian coordinate system dichotomy rule, establish a global grid subdivision model and iteratively divide the earth into longitude and latitude dichotomies, and perform binary coding on each grid;
[0054] The Cartesian coordinate system dichotomy rule is: if this plane represents t...
