Guam 3m Terrain Mesh SP2

Developed by Chris Britton for FSX, P3Dv2, P3Dv3 and P3Dv4.

Emerald Scenery Design is proud to present to you: the entire Island of Guam in super high resolution 3 meter/px Terrain Mesh. As an added bonus, we have also thrown in the Northern Mariana Islands for Free!

Now in Service Pack 2, we have reworked the entire scenery. All data has been reprocessed and exported at double the bit depth to allow for super smooth elevation transitions. We have also added a configurator to better handle 3rd party scenery compatibility.

What is Terrain Mesh?

The world is filled with dips, hills, mountains, and valleys. Without these features, our planet would be rather flat and boring. Terrain Mesh is rendered from Digital Elevation Models that are acquired from the scanning of the earth's surface. These models depict all the land features of earth, which we then convert to a format in which FSX can read. In turn, this recreates all the crisp land features that we see every time we fly.

Please note that due to this terrain data being very high resolution, airport plateaus cannot be completely fixed. We have made adjustments to help lessen these effects and find a balance in elevation, however this does not completely fix the issue.
