Description
A one-step tool for the creation of selected terrain parameters related to channels.For details look at the description of the tools used for processing:
- [ta_preproc] Sink Removal
- [ta_preproc] Fill Sinks (Wang & Liu)
- [ta_preproc] Breach Depressions
- [ta_channels] Channel Network and Drainage Basins
- [ta_channels] Watershed Basins (Extended)
- [ta_channels] Overland Flow Distance to Channel Network
- [ta_channels] Vertical Distance to Channel Network
