Create WAsP Roughness Map + Obstacle objects


Could anybody pls explain me in details how to create Roughness Map and obstacle objects in GM 18?

I have created contour map in GM and exported it as Vector/WAsp map. I opened it in WAsP software but when i tried to synchronize it with google earth i got ERROR related to COORDINATE system transformation. Do anybody know what to do about it?
