Longley Rice Terrestial Propagation

The Terrain Type

The terrain type is derived from the calculation of the average height along the terrain profile.

Possible Terrains

Delta Elevation Terrain Type Value
Δ ≤ 10 Flat 0
Δ ≤ 50 and ≥ 10 Plains 30
Δ ≤ 500 and ≥ 50 Hills 90
Δ ≤ 2500 and ≥ 500 Mountains 200
Δ ≥ 2500 Rugged Mountains 500

Where:

Δ = elevation_sum / elevation.Length
