Topographic Roughness Index (TRI) in ArcGIS using DEM
The Topographic Roughness Index provides a quick and easy way to calculate a topographic roughness ratio using DEM. For each cell of the GRID model, the difference in altitude between the central cell and the other eight surrounding it is calculated. The Index's highest values are given by the sharp ridges and the slopes of the steep.
