Terrain Classification Index (25 m Grid Data) (WMS Service)

The Terrain Classification Index = (TCIlow) is a dimensionless index in the range of 0-2. It exaggerates the slightest elevation differences, especially in low ranges. Even with the slightest relief differences, clots and flat sinks are recognizable. In the vicinity of anthropogenic structures such as dikes, dams or heaps, residues or artifacts can distort the values. The relief classification index TCIlow is based on the corrected and thinned grid (DGM25) and is calculated from the complex relief parameters height over depth line, catchment area size and modified soil moisture index (BOCK & Böhner & CONRAD & KÖTHE & Ringeler (2007).
