Geomorphographic map of Lower Saxony (10 m grid data)
Description
The geomorphographic map (GMK10) is based on the generalized digital elevation model of Lower Saxony (DGM1) after 10 m.
The derivation was carried out on the corrected and thinned to 10 m grid without orders and levies (DGM10oAF). Simple relief forms are presented in accordance with the 5th edition of the soil mapping guide (Ad hoc AG Boden 2005). The depth ranges are shown from a catchment area size of 40 ha. They are broken down by catchment area size and a relative ‘height’ (lowering areas in the lowering area, crowning areas in the lowering area). The aim is to identify smaller channels and relative high altitudes in the main sink area. The slopes are divided into four groups of inclination classes (N 0-1 = flat to flat, N 2-3 = slopes with a clear tendency to erosion, but agriculturally usable, N 4 = arable no longer usable, N 5-6 = steep slopes with a clear tendency to gravitational slope movements). This summary is made with regard to the use for the BK50 of Lower Saxony. Vertex areas are flattened areas in high altitudes. Like the slopes, they are separated into two grades (N 0-1 and N 2-3). Gradual vertices are specially designated, as these are often extremely flat locations and/or the soluble main location is missing.
