Kickoff with lightning talks

    • Wednesday, November 6, 2024, 12:00 PM - 1:15 PM ET
      • Lead: Heather Savoy, Amy Hudson

This session will have an introductory presentation about the working group and workshop goals plus lightning talks by ARS researchers and SCINet fellows about their research.

Lightning talk presenters

  • Georgia Harrison: An Independent Accuracy Assessment of Satellite-Derived Rangeland Fractional Cover
  • Efrain Duarte: Application of remote sensing tools for monitoring soil moisture in semi-arid ecosystems
  • Mahesh Lal Maskey: A Tool to Extract Actual Evapotranspiration from the USGS MODIS Data Portal
  • Amitava Chatterjee: Soil Health Classification Framework for Florida Soils using K-Means Clustering
  • Andrea Albright: Irrigation pond water storage variability using in situ and UAS data
  • Kossi Nouwakpo: A deep learning approach for irrigation methods mapping

A recording of the session will be added after the workshop concludes.

Tutorial setup instructions

Steps to prepare for the tutorial sessions:

  1. Login to Ceres Open OnDemand at https://ceres-ood.scinet.usda.gov/. For more information on login procedures for web-based SCINet access, see the SCINet access user guide.

  2. Open a command-line session by clicking on “Clusters” -> “Ceres Shell Access” on the top menu. This will open a new tab with a command-line session on Ceres’ login node.

  3. Request resources on a compute node to avoid using the login node for data transfers by running the following command.

     srun --reservation=workshop -A geospatialworkshop -t 00:30:00 -n 1 --mem 8G --pty bash

  4. Create a workshop working directory and copy the workshop materials into it by running the following commands. Note: you do not have to edit the commands with your username as it will be determined by the $USER variable.

     mkdir -p /90daydata/shared/$USER/
 cd /90daydata/shared/$USER/
 cp -r /project/geospatialworkshop/2024/tutorial* .

  5. Create a symbolic link to the virtual environment. In the workshop project space, there is a grwg_2024_env virtual environment for the Python packages we will be using during the workshop tutorials.You will create a symbolic link to that virtual environment from your workshop working directory. You will then have a shortcut called my_grwg_2024_env in your workshop working directory that points to the virtual environment so you can easily access the virtual environment from VS Code.

     ln -s /project/geospatialworkshop/2024/grwg_2024_env/ /90daydata/shared/$USER/my_grwg_2024_env

  6. Setup the kernel for JupyterLab. You will create a kernel called grwg_2024_env to access from JupyterLab Server. Run the following commands to activate the workshop’s virtual environment and create a new kernelspec from it:

     source /project/geospatialworkshop/2024/grwg_2024_env/bin/activate
 ipython kernel install --name "grwg_2024_env" --user

  7. Stop the interactive job on the compute node by running the command exit.
