When starting to make scenary it's important to know scenary types and in which order they are shown.

Terrain mesh is the shape of the ground. It is the mountains, the valleys and the plains. Other elements of the terrain engine include phototextures, flatten polygons, and various lines and polygons, such as transportation elements, lakes, streams, coastlines, and airport property polygons. They all work independently and are blended together at runtime to create the scene out your window at any given moment, and FS does this many times a second. We will be focusing only on the terrain mesh portion of that mixture.

The resolution of the terrain mesh generally determines its detail and accuracy. Very low-resolution terrain has a much farther distance between elevation points, sometimes up to a kilometer, which results in rounded approximations of even the most craggy mountain ranges. As the distance between elevation points decreases, the detail and accuracy increases. This is due to an exponential increase in the number of elevation points as the distance between them decreases from 1226m to 612m to 306m to 153m to 76m to 38m to 19m to 10m. It is at the lower resolutions (38m, 19m and 10m) where detail and accuracy are brought into a sharp focus and your enjoyment of the FS environment is brought to a new level. The higher the resolution, the more detailed and accurate the terrain (output being as good as the source data). The lower the resolution, the less detailed the terrain.
