1- Is it possible to import from Google Earth not just the Terrain, but other objects like roads, buildings etc as well ? 2- Is it possible to control the size of the area which is imported?
Hi Rachel, no, at this moment is not possible to import roads, buildings, etc.
Regarding to the area, it's taken from the Google Earth view, so you can control it just by zooming in and out in Google Earth. You can also use a non perpendicular view to get a sort of conical area, though this is not recommended. Once you have imported the lines from Google Earth and generated a Lands Terrain based on them, you are free to redefine the boundary.
