Here is two different approaches, and I would like to get your opinion. There are two problems in this ticket, one is the topography field gets smoothed when user applies any smoothing request, and the second is the topography filed is no longer valid after the smoothed. So the first approach is to solve the second problem and ignore the first one, assuming the user does't care that much. If the user does care, then your suggestion about the formula is the answer. The second apporach is to remove the smoothing option when you have something over the topography. What do you think?
