StormVia aggregates public, partner, and commercial data sources for operational awareness. This page is the canonical inventory for what each source powers, the attribution text it requires, and any restrictions on how StormVia should use it.
StormVia Use
Forecasts, alerts, observations, hazardous weather outlooks, AFDs, DSS-linked products, and weather maps.

StormVia Use
Convective outlooks, mesoscale discussions, watches, categorical risk context, and severe-weather product links.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: NOAA Storm Prediction Center
Restrictions
Use official SPC graphics and text for authoritative probabilities. StormVia timing graphics are generated separately and labeled as non-official.
StormVia Use

License / Posture
Publicly accessible academic/public-service data
Required Attribution

License / Posture
USDM courtesy-required data product
Required Attribution
Map courtesy of the U.S. Drought Monitor, produced by the National Drought Mitigation Center at the University of Nebraska-Lincoln, USDA, and NOAA.
Restrictions
Weekly situational-awareness product. Courtesy line should appear anywhere drought maps or summary statistics are surfaced prominently.
StormVia Use
Backlog target for national flood outlook polygons and rainfall/flood support layers.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: NOAA Weather Prediction Center
Restrictions
Backlog item; add layer-specific attribution before shipping public-facing map use.
StormVia Use
Official AQI summary and forecast context in StormVia map and operations surfaces.
License / Posture
Public-sector API with key requirement and attribution requirement
Required Attribution
Air quality data provided by AirNow.
Restrictions

StormVia Use
Live map-native PM2.5 sensor layer for localized AQ detail.
License / Posture
PurpleAir data license / attribution required
Required Attribution
Sensor data courtesy of PurpleAir.
Restrictions
Crowd-sourced sensor network. Display as observational detail, not an official regulatory AQ designation.
StormVia Use
Smoke plume polygons and smoke-air-quality correlation context.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: NOAA Hazard Mapping System
Restrictions
Interpretive smoke product; pair with AQ and fire sources for operational context.
StormVia Use
Satellite fire detections and fire-support overlays.
License / Posture
NASA open data / public use
Required Attribution
Source: NASA FIRMS
Restrictions
Hotspots indicate detections, not confirmed incident perimeters or suppression status.
StormVia Use
Kp forecast, geomagnetic storm level, and quiet/elevated space-weather status cards.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: NOAA Space Weather Prediction Center
Restrictions
Situational-awareness context only in StormVia v1; not mapped as a geographic operational layer.
StormVia Use
Backlog target for significant earthquake points and impact context.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: U.S. Geological Survey Earthquake Hazards Program
Restrictions
Backlog item; event significance filtering should be applied before enabling by default.
StormVia Use
Disaster declarations and all-hazards support datasets.
License / Posture
Public Domain (17 USC § 105)
Required Attribution
Source: OpenFEMA / FEMA
Restrictions
Use for situational context, not incident command authority.
StormVia Use
Road conditions, incidents, closures, RWIS, traffic cameras, and construction context.
License / Posture
State government data
Required Attribution

Map imagery and basemap © Mapbox and OpenStreetMap contributors.
Restrictions
Must follow Mapbox attribution and logo requirements wherever their styles or tiles are displayed.
New StormVia data layers should not ship until they declare their source, usage, attribution text, and any commercial or operational restrictions. This registry is intended to keep the public-facing product, internal planning, and future backlog work aligned.
