Hi, I'm in the process of purchasing some land to start a homestead in a few years. I was wondering if anyone out there knows of any software that can take a topographical image from say Google Earth and render it in 3d. I was hoping to use this software to plan the homestead based on the current topography. Basically, I'm looking for software anyone could recommend for planning a homestead. I was hoping to be able to download a free version but any kind of software that can achieve this will do. Please let me know.
