EOMF-22. Modern Map Viewers at NOAA's National Centers for Environmental Information

NOAA's National Centers for Environmental Information (NCEI) hosts and provides public access to a wide range of environmental data, including coastal, oceanic, geophysical, and atmospheric data. NCEI has long made many of these datasets publicly-accessible through interactive mapping applications utilizing the legacy ArcGIS API for JavaScript 3.x and ArcGIS Server map services. NCEI is now working to modernize these web applications by taking advantage of ArcGIS Online (e.g. hosted feature layers and web maps/scenes) and the latest ArcGIS API for JavaScript 4.x. The new, easy-to-use map viewers are implemented using current well-supported web technologies such as React, TypeScript, and MUI. This poster will cover four new web mapping applications developed over the past year: Tsunami Events (1850-Present) Time-Lapse Animation, Trackline Geophysical Data Viewer, Ocean Exploration Data Atlas (showcasing data from the NOAA Ship Okeanos Explorer), and Historical Magnetic Declination.
