Thank you Justin9926. I will check that out. However I just made the size of my layout map the same dimensions as the terrain and it all looks great. If there is a yardage problem I am pretty sure I can just adjust the original layout. With a little trial and error I can bring it together. And the layout works prefectly by adding it as a texture to the terrain as RobC pointed out.
I do have one other question as long as I am at it. And that, and this may seem wild, is it possible to change the physics of the ball flight to adjust for lower gravity? This may not even be possible but it would save a lot of time for me to know up front that you can't do that. I am thinking of a golf course on planet Mars. Seriously.
By the way, anyone got a height map of Mars? LOLOLO, just kidding.

P.S. I watched the above video and it was very interesting. I can see many many uses for that grid technique.
