Find and View Data, Reports, and Other Products
Information and products are organized within four coastal change hazard themes: 1) Present-day Storm Scenarios, 2) Observed Shoreline Change, 3) Future Shoreline Change, and 4) Future Coastal Hazards. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.

Data & Developer Access
All data in the portal are available in machine-readable form without a browser, API key, or login. Data are produced by the U.S. Geological Survey and, as works of the U.S. Government, are in the public domain.
Catalog
The full catalog is available as a single JSON document — every active item with its title, descriptive summaries, keywords, spatial extent, and map-service endpoints:
https://marine.usgs.gov/coastalchangehazardsportal/data/item/uber?subtree=true
A sitemap lists the page and JSON endpoint for every item.
Individual Items
Each item has a stable identifier and is available as both a citable web page and a
JSON record. Replace {id} with an item identifier:
- JSON record:
https://marine.usgs.gov/coastalchangehazardsportal/data/item/{id} - Web page:
https://marine.usgs.gov/coastalchangehazardsportal/ui/info/item/{id}
The per-item JSON record includes the data download link and the FGDC metadata link; these are trimmed from child items in the full catalog tree to keep it compact.
