Snow Accumulation
Snow Accumulation Overview
The purpose of the snow accumulation feature is to visually represent accumulated snow throughout the entire global database. This feature affects the visual representation of the terrain texture as well as the material returns.
| Visual Examples | ||
|---|---|---|
Snow Accumulation at 0%
| Snow Accumulation at 50%
| Snow Accumulation at 100%
