This Jupyter Notebook and data serve as an illustration for the evaluation of Height Above the Nearest Drainage (HAND) using TauDEM. This depends on TauDEM functions and a user either needs to install TauDEM (see http://hydrology.usu.edu/taudem) or use a platform where this is pre-installed such as CyberGIS Jupyter for Water (https://go.illinois.edu/cybergis-jupyter-water/) with a TauDEM Kernel.
How to run the Hand Workflow
This workflow has been developed and tested on the CyberGIS-Jupyter for Water platform linked to HydroShare using the TauDEM-2021-12 Kernel. To execute the workflow elsewhere you may need to account for differences between this platform and the platform being used.
STEP_0 Join the CyberGIS-Jupyter for Water HydroShare Group
To use the CyberGIS-Jupyter for Water platform you need to have a HydroShare user account be a member of the CyberGIS-Jupyter for Water HydroShare Group. - Create a HydroShare account at http://www.hydroshare.org - Request to become a member of the CyberGIS-Jupyter for Water (CJW) group at the CyberGIS-Jupyter for Water platform
Group membership is used manage the use of the community computing resources available in CyberGIS-Jupyter for Water
STEP_1 Open With CyberGIS-Jupyter for Water.
- Click the OpenWith button in the upper-right corner of this HydroShare resource webpage;
- Select "CyberGIS-Jupyter for Water";
- Authenticate and allow access to HydroShare content from CJW;
This should open the CyberGIS-Jupyter for Water Jupyter computing platform and transfer the files from HydroShare to the platform for work there. Note that the CJW file workspace is different from HydroShare resource file space, so any work you do in CJW would need to be copied back to HydroShare or elsewhere if you want to preserve or share it.
STEP_2 Execute HANDWorkFlow using HANDWorkFlow.ipynb
This notebook demonstrates the general procedure to calculate HAND (Height above the Nearest Drainage) using TauDEM (https://hydrology.usu.edu/taudem/taudem5/). Run all cells to completely execute the notebook, or run one cell at a time to see the process involved.
