  • The simplification always returns a valid geometry.
  • Simplified geometries require less storage space and fewer spatial operations during geospatial manipulations. Consequently operations on simplified geometries generally perform faster.
  • Smaller tolerance values result in a geometry closer to the input geometry, but will remove fewer vertices. Larger tolerance values will remove more vertices, but the resulting simplified geometry will be less similar to the original input.
