Research on Visualization Method of Large-scale User Location Distribution Based on CesiumJS
In order to cater to the advanced user positioning function of the Beidou satellite navigation system, the simulated domestic positioning point data is used to realize the visualization of user distribution in the form of a heat map through the Webside 3D visualization technology. In the case of a large amount of rendering data, by optimizing the kernel density estimation algorithm and optimizing the calculation method of the data points in the raster, the effect of real-time rendering of the heat map in the optimal display form is realized with the change of the viewpoint position, and the rendering Performance has been significantly improved.
