I'd like to know if there is a software for FSX that replaces the flat ground imaging and the default FSX autogen to the 3D like buildings and roads of X-Plane. Any software similar to this, I'd like to hear about it!

 

Thanks.

I'd say FTX Global and Vector are what you are looking for; as close as you can come to X-Plane's autogen.
