Data and layers of 3D scene |
A 3D scene is a scene in which one or more layers of a 3D service are stacked in a certain order and displayed in a window. The main body of a 3D scene is a 3D sphere of simulated earth(with a radius of 6378137 meters). This sphere has a geographic reference. Points on the sphere are positioned with longitudes and latitudes, and can also be easily viewed through the longitude and latitude grid on the sphere provided by the 3D scene. At the same time, it uses global remote sensing image as a backgroud convering the surface of the sphere, simulates the earth's environment, including the universe of the sky, the atmosphere, the fog environment of the earth's surface, etc., to make it more real.
