Upcoming Event

NOAA NCEI/CIRES Open-Source Workflows for Coastal DEM Generation

Thursday, April 16, 2026

2:00 PM to 3:00 PM Eastern

Speaker: Christopher Amante (NOAA/NESDIS/NCEI through CIRES)

Summary: This webinar will highlight open-source workflows for building coastal digital elevation models, from streamlined data discovery and processing to reproducible terrain generation. It will demonstrate how these modular approaches can integrate topographic and bathymetric datasets to support more reliable coastal water prediction and hazard applications.
