Thanks. Though it would be possible but unsure how to implement it. I'll have a bash later. Will try and source the terrain topographics and if successful, I will post findings here.
Once again... thanks.

Just wondering if you could take a plan view of a coaster and paste it on the terrain and use it like a template? Was going to use a google map image if possible. This is the map location that I was planning on using. https://www.google.co.uk/maps/place/Alton,+Stoke-on-Trent+ST10+4DB/@52.9871911,-1....

When you import a coaster from NL1 you should get another window pop up asking about Import terrain and Import trees. Not sure if that includes the scenery as well but no harm in trying.
