3D Nation Study Hub Site now available!

The 3D Nation Elevation Requirements and Benefits Study focuses on 3D elevation data on land and underwater.

A new ArcGIS Hub Site sharing the results of the 3D Nation Elevation Requirements and Benefits Study, which was published in September 2022, is now available. The site currently features a tool which allows users to filter business use ranks by each state. The site will be updated with more immersive dashboards as they become available. This study was sponsored by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS), and conducted by Dewberry. The study documents nationwide requirements and benefits of 3D elevation data both on land and underwater. The study also estimates the costs associated with meeting these requirements and evaluates multiple scenarios for enhancing national elevation mapping programs.

NOAA-NSF collaboration – evaluating coastal models utilizing Texas Advanced Computing Center services

The Unified Forecast System (UFS) is a proposed community-based earth modeling system that is designed to incorporate oceanographic forecast model core(s) into a simplified NOAA modeling suite. This simplification is intended to reduce the footprint of the number of NOAA models and thus reduce development, operations, and maintenance.

Introducing the Inland-Coastal Flooding Operational Guidance System (ICOGS)

Where the river meets the sea can be both a turbulent and vulnerable space, particularly during strong storms when heavy precipitation and storm surge intersect. This intersection is known as “compound inland-coastal flooding,” and until now, had not been carefully studied and implemented in forecasting centers for public guidance due to its inherent complexity. NOAA’s Office of Coast Survey and the Virginia Institute of Marine Science recently developed the Inland-Coastal Flooding Operational Guidance System (ICOGS), the world’s first three-dimensional integrated compound inland-coastal flooding guidance system.
