NOAA NCEI/CIRES Coastal DEM Workshop

Open-Source Workflows for Coastal DEM Generation¶

Hosted by: NOAA NCEI and CIRES for NOAA’s Coastal Coupling Community of Practice (CC CoP) Bathymetric Data Working Group
When: Thursday, August 13, 2026, 2:00–4:00 p.m. Eastern
Where: Virtual workshop — Register here

Workshop abstract¶

Scientists from NOAA’s National Centers for Environmental Information (NCEI) and the Cooperative Institute for Research in Environmental Sciences (CIRES) will lead a hands-on introduction to open-source coastal DEM workflows.

Using a hosted JupyterHub environment, participants will inspect and run a reproducible workflow for generating 1/9 arc-second coastal DEMs for Newport, Oregon and Sarasota, Florida. The workshop will demonstrate how tools from the Continuous DEMs project support source-data access, processing, vertical datum harmonization, DEM generation, and independent validation.

This workshop builds on the April 16, 2026 webinar, “Open-Source Workflows for Coastal DEM Generation.”

Workshop goals¶

By the end of the workshop, participants will be able to:

• Build a coastal DEM from multiple topographic and bathymetric datasets.

• Understand how source data are discovered, standardized, filtered, prioritized, and combined.

• Understand why coastline masking and multiresolution interpolation are important for coastal DEM generation.

• Inspect DEM provenance and supporting outputs.

• Apply the same standardized recipe to another coastal region DEM.

• Independently evaluate the DEMs using ICESat-2.
