TG2 does not have this functionality currently. If you are handy with coding or scripting, you could probably make either a batch file or some kind of small program to edit the TGD file and call the renderer, programmatically adjusting the camera position. That's the only way you could hope to achieve that level of detail at this point. Keeping in mind that, for the entire planet, that would be a whole lot of data and a lot of render time as well.
