1 - Getting Started - CUDEM/Coastal Coupling Workshop 2026

Getting Started¶

Welcome to the NOAA NCEI/CIRES Coastal DEM Workshop.

In this module, we will get everyone into JupyterLab, confirm that the workshop tools are ready, and set up the workspace we will use for the exercises.

Goal: Get connected, open a terminal, confirm the tools, and prepare workshop data.

1. Open the workshop JupyterHub¶

Open the Coastal Coupling Workshop JupyterHub.

Enter a username that is unique from other participants.
Use the workshop password shared by the instructors in the chat.
Start your JupyterHub server.
Wait for JupyterLab to open.

For more detail on signing in and starting your server, see Starting your server.

2. Open a terminal¶

In JupyterLab:

Under Other, click Terminal.

You should now see a command prompt.

3. Confirm the workshop tools¶

The workshop environment already includes the four main tools we will use.

Run:

fetchez --version
transformez --version
globato --version
ivert --version

Each command should print a version number.

Tool	Role in the workshop
Fetchez	Orchestrate the workflow and discover and stream source data
Transformez	Support horizontal and vertical reference transformations
Globato	Provide elevation-specific tools for building the DEM
IVERT	Evaluate the DEM with independent observations

We will see how these tools work together as we build and evaluate the DEMs.

4. Set up your workshop workspace¶

The workshop datasets have already been prepared so we can spend our time building and exploring DEMs rather than waiting for large downloads.

Run:

bash ~/shared/setup_workshop.sh

When setup finishes, check the workspace:

ls ~/workshop

You should see:

ivert
newport_data
newport_dem
reference_outputs
sarasota_data
sarasota_dem

During the workshop, use ~/workshop for the prepared data, DEM outputs, and reference outputs.

Directory	Purpose
`~/workshop/newport_data`	Prepared Newport source-data cache
`~/workshop/sarasota_data`	Prepared Sarasota source-data cache
`~/workshop/ivert`	Prepared IVERT data used later for DEM evaluation
`~/workshop/reference_outputs`	Known-good Newport and Sarasota outputs available as workshop fallbacks
`~/workshop/newport_dem`	Your Newport DEM outputs
`~/workshop/sarasota_dem`	Your Sarasota DEM outputs

~/workshop points to /tmp/workshop, which is temporary storage attached to your JupyterHub server.

If your server is stopped and recreated, rerun:

bash ~/shared/setup_workshop.sh

Download or copy any DEM results you want to keep before ending your workshop server.
