And step 106, determining the positioning data of the boundary points according to the plane coordinates of the boundary points.
In the embodiment of the present application, the electronic fence is finally marked on the electronic map, and therefore, the plane coordinates of the boundary points need to be converted into longitude and latitude, that is, positioning data.
And step 107, drawing the electronic fences of the towers on the electronic map according to the positioning data of the boundary points.
In the embodiment of the application, after the plane coordinates of the boundary points are obtained, the plane coordinates of the boundary points are converted into corresponding positioning data, the positioning data of the boundary points are marked on the electronic map, and then the electronic fence is drawn according to the positioning data of the marked boundary points.
