National Risk Index (NRI)

This online mapping application from FEMA identifies communities exposed to 18 natural hazards, visualizing natural hazard risk metrics and including data about expected annual losses, social vulnerabilities, and community resilience. 

The National Risk Index's interactive web maps present data at the county and census tract level via geographic information system (GIS) feature services for custom analyses. These data layers offer a holistic view of community risk to natural hazards via online maps and data.

The NRI can assist communities in:

Chucktown Floods: Adapting to Flooding in Charleston

The Chucktown Floods site gives municipalities, stakeholders in business and industry, and individual homeowners a way to navigate available resilience tools and data relevant to flooding in the Charleston County area. The site is designed to reduce barriers to accessing data associated with flooding vulnerability and enhance decision making that results in improved resilience to future flooding events in the region.

Southern California Coastal Ocean Observing System (SCCOOS) | An IOOS Regional Data Portal

The Southern California Coastal Ocean Observing System (SCCOOS) works to collect and integrate oceanic and coastal data into viable observations and products. Users can browse through information on several different topics, including water quality, salinity levels, currents, etc. Such data can serve a great number of stakeholders, area managers, decision makers, scientists, and the general public.

Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) | An IOOS Data Portal

The Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) brings weather and ocean data for fisheries, commercial ships, and emergency weather services together for public safety. The organization works to improve the monitoring of water quality, algal blooms, flooding and erosion. Users can search through a variety of data services and products, including buoy observations, historical data, weather forecasts and satellite information.

Northwest Association of Networked Ocean Observing Systems | An IOOS Regional Data Portal

The Northwest Association of Networked Ocean Observing Systems (NANOOS) represents an amalgamation of 65 separate products available for decision makers' use. This toolkit was created to unite the vast amount of individual pre-existing observing systems like ocean buoys, satellites, and tide gauges into one cohesive network, ensuring better communication between the systems. With this network, users can efficiently gather observational and model data that promotes the proper management of the oceans and estuaries in the Pacific Northwestern region.

Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) | An IOOS Regional Data Portal

The Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) gathers marine and coastal data and makes them available as accessible information products. MARACOOS focuses their research on coastal hazards, fisheries, maritime and commerce safety, energy ,and water quality, working to bolster the economy as well as local ecosystems and citizens. The group makes an effort to collaborate with people who work directly in the Mid-Atlantic area in order to ensure the quality of their data.

Great Lakes Observing System | An IOOS Regional Data Portal

The Great Lakes Observing System (GLOS) offers data on maritime safety, ecosystems and fisheries, public health, and climate adaptation and seeks to facilitate the gathering, administration, and dispensing of Great Lakes regional data. This data is visible through either the catalog or map view, both of which are good visualization methods depending on users' preferences. The tool is meant for scientists, managers, and industry stakeholders. 

Gulf of Mexico Coastal Observing System (GCOOS) | An IOOS Regional Data Portal

The Gulf of Mexico Coastal Observing System (GCOOS) coordinates information gathered by federal, state and private partners, ensuring that data are timely, reliable, accurate and available to everyone — from weather forecasters to Coast Guard first responders — to ensure a healthy, productive ocean and resilient coastal communities for the Gulf’s 14 million residents and the $234 billion annual economic benefit it provides to the U.S. economy.
