SAGA.ta_morphometry.14: Relative Heights and Slope Positions

The tool allows one to calculate several terrain indices from a digital elevation model.<br/><br/>General information on the computational concept can be found in:<br/>- Boehner, J. and Selige, T. (2006): Spatial prediction of soil attributes using terrain analysis and climate regionalisation. In: Boehner, J., McCloy, K.R., Strobl, J.

Inputs

Élévation

Please set a value for DEM.

The parameter weights the influence of catchment size on relative elevation (inversely proportional).

number

The parameter controls the amount by which a maximum in the neighbourhood of a cell is taken over into the cell (considering the local slope between the cells). The smaller 't' and/or the smaller the slope, the more of the maximum value is taken over into the cell. This results in a greater generalization/smoothing of the result. The greater 't' and/or the higher the slope, the less is taken over into the cell and the result will show a more irregular pattern caused by small changes in elevation between the cells.

number

The parameter controls the position of relative height maxima as a function of slope.
