Vertical Distance to Channel Network
(c) 2002 by O.Conrad
This module calculates the vertical distance to a channel network base level. The algorithm consists of two major steps:
1. Interpolation of a channel network base level elevation grid
2. Subtraction of this grid from the original elevations
Parameters
- Grid system
Grid system
- Grid system
- Elevation
Input Grid
- A grid that contains elevation data.
- Channel Network
Input Grid
- 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.
- Vertical Distance to Channel Network
Output Grid
- The resulting grid gives the altitude above the channel network in the same units as the elevation data.
- Channel Network Base Level
Output Grid
- This optional grid output contains the interpolated channel network base level elevations.
- Tension Threshold [m]
Floating point
-
- Keep Base Level below Surface
Boolean
