An across-terminal three-dimensional digital earth interaction method based on a BS architecture can automatically detect a terminal form and a browser version, performs responsive layout and self-adaptive interface control generation according to the screen resolution and performs self-adaptive interaction event binding and generation according to the terminal form. By adopting the method, normal display of a set of system on a desk top side and a mobile terminal browser can be achieved, the operation is convenient, accordingly across-terminal platform access is achieved, the system development cost is reduced, and user experience is improved.
