SAGA.ta_channels.3: Vertical Distance to Channel Network

This tool calculates the vertical distance to a channel network base level. The algorithm consists of two major steps:<br/> 1. Interpolation of a channel network base level elevation<br/> 2. Subtraction of this base level from the original elevations<br/>

Inputs

A grid that contains elevation data.

format
href
Please set a value for ELEVATION.

A grid providing information about the channel network. It is assumed that no-data cells are not part of the channel network. Vice versa all others cells are recognised as channel network members.

format
href
Please set a value for CHANNELS.

Maximum change in elevation units (e.g. meter), iteration is stopped once maximum change reaches this threshold.

number

Maximum number of iterations, ignored if set to zero

integer

Keep Base Level below Surface

boolean

Outputs

The resulting grid gives the altitude above the channel network in the same units as the elevation data.

transmission

This optional grid output contains the interpolated channel network base level elevations.
