If you don't know how to set up new scenery read this online tutorial by Tim Dickens.
Mesh scenery is made using the Terrain SDK based on the public domain United States Geological Survey data, which provides accurate elevation data for the Earth's entire surface. The USGS data is important because the FS2000 default scenery uses a far simpler scenery model than the simulator engine is actually capable of displaying, and this will be familiar to anyone who has explored the FS2000 world to any extent.
The default terrain has elevation points spaced 1 kilometer apart. This provides a barely adequate representation of the real world, as the subtle nuances of valleys and peaks are lost, creating a dull, rolling appearance in even the most jagged and extreme terrain. This high-resolution terrain upgrade brings out the sharp relief by increasing the resolution to 153 meters between elevation points, creating a much more realistic and often spectacular representation of the real world terrain.
Advise: Mesh scenery replaces the default scenery and you need a fast PC (P500+)to run it. Download one scenery first and test the result, before you download and install all files!
There are a few people around making mesh scenery's for the United States. The largest collections have been made by Justin Tyme (not free) and by Eddy Denney, the latter are free and downloadable on this page. A review of Eddie Denney's scenery can be found here.
