Sources and transparency
ATLAS has an informational and educational purpose: it makes recent natural events easier to understand through a global representation. It is not an alert, forecasting, operational-monitoring or emergency-response system. Sources are identified in event details and on this page.
The table includes sources queried for events, complementary cyclone-status checks, and separate layers or resources. NOAA/NWS and JTWC advisories confirm activity only; they do not supply the card's time-specific observation.
| Source | Use in ATLAS | Nature |
|---|---|---|
| NASA EONET | Wildfires, cyclones and volcanic activity when recent records exist. | Open, non-exhaustive catalogue of curated natural events. |
| USGS Earthquake Hazards Program | Recent earthquakes, magnitude, depth, position and updates. | Public GeoJSON feeds. |
| Copernicus EMS Rapid Mapping | Configured query for recent emergency-mapping activations related to wildfires; floods remain planned and are not advertised as operational; if the service cannot be reached from the browser, it contributes no situations. | An activation is an official mapping request: by itself it does not confirm the phenomenon, its full extent or continuing status. For floods it is not presented as a global observation of inundated extent. © European Union; attribution required. |
| Copernicus EFFIS | Recent MODIS/VIIRS NRT-derived burned-area perimeters with dates, area and administrative location. | ATLAS queries the official WFS, preserves geometry and applies a 100 ha and seven-day threshold. A derived burned area does not by itself confirm an active wildfire, its cause or local impacts. |
| Natural Resources Canada · CWFIS (Canadian Forest Service) | Active Wildfires in Canada, layer public:cwfif_national_activefires: active fires reported by Canadian agencies, with identifier, control status, reported area and status date. | ATLAS normalizes and adapts the data, excludes prescribed burns and records below 100 ha, and applies the recency window to the status date. The location is approximate and does not necessarily represent the perimeter. |
| INPE · Programa Queimadas | Eventos de Fogo: ATLAS autonomously queries the official active-events KML through a function that delivers only events explicitly classified by INPE as Incêndio. | ATLAS normalizes the records, preserves the KML SHA-256, and checks the freshness of the file and each last hotspot. Isolated hotspots, possible starts and anthropogenic activity are excluded. Classification is provisional and the point is not a confirmed perimeter. |
| ACT Emergency Services Agency | GeoRSS of current Australian Capital Territory incidents, restricted to vegetation fires. | ATLAS retains the incident ID and dates and excludes planned burns and non-fire services. The incident feed, distinct from the warning feed, is attributed to ACT ESA under CC BY 4.0; the location is indicative. |
| NSW Rural Fire Service | New South Wales Bush Fire and Grass Fire incidents; planned burns and other incidents excluded. | CC BY 4.0; © State of New South Wales (NSW Rural Fire Service). Locations are approximate. |
| NOAA IBTrACS v04r01 | Global tropical-cyclone tracks from the ACTIVE subset, consolidated with NASA EONET and, where applicable, JMA by system identity, time and position. | Provisional best track updated several times per week. Track, intensity and status may be revised; systems marked as dissipated do not remain in the active selection on their own. |
| Japan Meteorological Agency (JMA) · RSMC Tokyo (cyclones) | Current analyses of Western North Pacific cyclones: position, 10-minute sustained wind, classification and time from the same observation. Forecasts are not treated as observations. | A newer compatible observation can replace an earlier EONET or IBTrACS observation without mixing time-specific fields. JMA information adapted by ATLAS under the Public Data License 1.0, unless otherwise indicated. |
| NOAA/NWS (NHC, CPHC and Guam) and JTWC | Operational advisories checked when ATLAS opens and periodically, only to determine whether a cyclone can appear under “Active situations”. | ATLAS requires a recent tropical confirmation linked to the system identifier or a current JMA tropical analysis; a later final advisory prevents it being presented as active. If a service does not respond, the last confirmation remains valid only until 12 hours after issuance. These advisories do not replace the card's position, wind and time observation. |
| USGS Volcano Hazards Program | Official notices for U.S. volcanoes with level, colour and latest update. | A notice may describe a pause or a level change and does not necessarily imply an ongoing eruption. |
| GeoNet · Earth Sciences New Zealand | Current official status of New Zealand volcanoes with an alert level above zero. | The level describes volcanic unrest; it does not confirm an eruption. Retrieval time is not presented as onset or observation time. GeoNet data adapted by ATLAS under CC BY 3.0 New Zealand, acknowledging the programme and its sponsors. |
| Japan Meteorological Agency (JMA) · volcanoes | Japanese volcanic alerts and activity explanations with alert level, plus explicitly observed eruptions, preserving volcano, identifier, issue time, target time and observation time where available. | ATLAS distinguishes notices from observed eruptions and excludes ash forecasts as evidence of eruption. JMA information adapted by ATLAS under the Public Data License 1.0, unless otherwise indicated. |
| Copernicus GDO · Meteorological Drought Tracking 2.0.0 | Planned territorial meteorological-drought layer, not advertised as operational; its design considers only clusters explicitly marked on-going by the source. | SPI-3 ERA5 product clustered with DBSCAN, CC BY 4.0. It is not a point event or a direct observation of local impacts; consolidated polygons are excluded. |
| Natural Earth 1:50m · Admin 0 Map Units and Tiny Countries | Land, offshore, open-ocean, country, territory and region geoclassification. | Public-domain data, reproducibly simplified. Cartographic boundaries do not express a political position by ATLAS. |
| NASA Blue Marble | Daytime Earth texture. | Earth-observation imagery. Credit: NASA Earth Observatory. |
| NASA Black Marble | Nighttime Earth texture and lights. | Night-light imagery. Credit: NASA Earth Observatory. |
| CountryInfo | Localized names and search focus points; it is not used as the worldwide geometry for event association. | Open dataset distributed under the MIT License. |
| geoBoundaries gbOpen | Multipart territorial geometries in the local catalogue for Spain, Portugal and Fiji. | Open geographic data; attribution and conditions are documented in the local credits. |
Retained snapshots without current data
Local files from the following sources retain their attribution, but their August 2026 copies no longer feed visible situations. ATLAS requires a snapshot less than 24 hours old; an old incident or notice date is not treated as a current status.
| Source | Retained scope | Terms |
|---|---|---|
| Emergency Management Victoria · VicEmergency | Victoria vegetation-fire incidents identified by official type and ID. | CC BY 3.0 Australia; State of Victoria, Australia. CAP warning level is not physical fire intensity. |
| Queensland Fire Department | FIRE VEGETATION records; FIRE PERMITTED BURN and other types excluded. | CC BY 4.0; Queensland Fire Department. Positions indicate the general area. |
| INGV · Osservatorio Etneo | Public notice and VONA metadata for Etna, Stromboli and Vulcano. The date is official publication, not physical onset; VONA is an aviation code only. | CC BY 4.0; INGV-OE. PDF contents are neither read nor reused. |

What you can do
The general guidance in “What you can do” is supported by the following official resources:
- Wildfires: WHO and IFRC.
- Cyclones: IFRC.
- Earthquakes: USGS and WHO.
- Volcanic activity: USGS, WHO and IFRC.
- Planning reference, with no advertised operational coverage. Floods: WHO and IFRC.
- Planning reference, with no advertised operational coverage. Droughts: WHO and IFRC.
Visual resources
The stars are a visual background generated in code and do not represent real astronomical positions. The clouds are a procedural visual representation and do not show current cloud cover. The oceans are enhanced in the shader from the daytime texture; no water layer or additional API is used. The daytime and nighttime textures are credited to NASA Blue Marble and NASA Black Marble.
NASA EONET is a catalogue that aggregates events from different sources. ATLAS preserves original links when available, normalizes geometries and dates, and uses a representative location for the marker; that location does not always describe the full affected extent.
Each provider adapter is queried independently. ATLAS publishes one provisional selection and one final selection of up to 250 events so that a slow or unavailable source does not block the globe. ATLAS distinguishes instrumental observations, curated events, official mapping activations, agency-reported active fires, provider-classified events, derived burned areas, provisional cyclone tracks, official volcano notices and official volcanic operational communications. A Copernicus Rapid Mapping activation or EFFIS perimeter is not presented as confirmation of an active wildfire. Volcanic activity does not automatically mean eruption. When two sources match strongly in space, time and meaning, one situation is retained with a primary source and supporting sources; uncertain cases are not merged.
Updates and cache
ATLAS requests the feeds when the experience opens. Timestamps from Copernicus EMS Rapid Mapping and the USGS Volcano Hazards Program that are documented as UTC are interpreted as UTC even when the source string omits a time-zone suffix. If a source fails, it may temporarily use a recent copy stored on the device and identifies this on screen. Old responses are not silently presented as current.
For INPE, a function queries the official KML when needed, checks its modification time and delivers a compact dataset. The response is cached briefly; only events with active fronts and a recent last hotspot are shown. If the file stops updating, it is not reused as though it were current. The August snapshot remains a historical file, not a source of current events.
The GDO layer is transformed at build time from an official archive pinned by URL and SHA-256. Each release preserves the observed period, production time and excluded counts; it does not update by itself between ATLAS releases.
The INGV-OE snapshot is generated locally from two public HTML tables and preserves each response's UTC date and SHA-256. It only reuses volcano, publication date, public communication type and VONA colour code. A later end or return-to-normal communication excludes the earlier signal. Its current copy has expired and contributes no situations; the browser does not query INGV and no PDF contents are accessed.
NSW RFS is queried directly from the browser when ATLAS opens and, while visible, at most every 30 minutes after a valid response. Planned burns, other incidents and closures are excluded. The validated backup expires after 60 minutes; a failure is not interpreted as an absence of fires. Publication and administrative update times are retained: they do not establish a new physical observation or the exact fire front. © State of New South Wales (NSW Rural Fire Service). For current information go to www.rfs.nsw.gov.au. Data transformed by ATLAS under CC BY 4.0.
VicEmergency and Queensland QFD snapshots are generated locally; the browser does not query their feeds. Their current copies have expired and contribute no incidents. Australian coverage is neither national nor complete.
Rules, selection and interpretation
The advertised operational phenomena are earthquakes, tropical cyclones, wildfires and volcanic activity. Floods and droughts remain planned. ATLAS distinguishes start date, last meaningful update, last observed activity and status. Seven days identify new or recently updated situations but are not a universal expiry. The window applies to the last meaningful update: 7 days for earthquakes, 21 for cyclones, 45 for wildfires and 90 for volcanic activity; the internal 30-day flood window is retained for planning. These windows retain prolonged activity only when there is a recent meaningful update and reduce old notices without new information.
The final selection deterministically applies evidence, recency, relevance and source quality. It then progressively reduces the marginal gain of further records from the same source within a category and of phenomena in the same category that occupy a 4-degree cell or lie within 100 km of events already selected. There are no continental quotas, automatic rewards for empty regions or hard provider caps. The global limit is set to 250 events after comparing 200, 250 and 300 with the current sources; 250 preserves fluidity and avoids the spatial concentration observed at 300. This priority organizes the visual narrative; it is not an official risk classification.
Visible titles are built from the original name without repeating the category, preserving place names when no safe translation exists. A coordinate is a reported or representative location, not necessarily the centre or full extent of the event. Territorial relations use simplified geometry and do not equal an official impact assessment.
Countries and cross-border effects
A point event is considered to occur in a country when its coordinate falls inside the simplified boundary. When that geometry cannot resolve a discontinuous territory, ATLAS may use a country or unambiguous region explicitly provided by the source and, finally, a local table of verified regions. Maritime events are not attributed by proximity alone. Tracks and polygons may associate a phenomenon with other territories. “Affects or is related” indicates an available geometric relationship, not an official impact assessment.
Day, night and rotation
Lighting approximately calculates solar declination, the equation of time and the subsolar point from UTC. Earth rotates at real speed; during a short visit the movement may be practically imperceptible.
Sources evaluated but not integrated
| Source | Assessment | Current decision |
|---|---|---|
| Copernicus GWIS NRT | Vector polygons of estimated burned area, derived from MODIS/VIIRS with fire IDs and dates. They are not confirmed incidents. | Not integrated yet: useful records exist in Africa and Siberia, but broad global queries can be truncated or return malformed responses; complete retrieval, deduplication and mobile cost must be secured before displaying them as estimated areas. |
| GDACS · wildfires | Derived alerts and episodes, often associated with the same GWIS areas or EONET events. | Not integrated: centroids and green-level notices should not be interpreted as locally confirmed wildfires; incremental value does not yet outweigh duplication and ambiguity risks. |
| NASA FIRMS | Near-real-time thermal detections; the API needs a free key and can return tens of thousands of hotspots per day. | Not currently integrated: each hotspot is not a wildfire. ATLAS has a local preprocessor that queries 13 controlled regions for 1–5 days, rejects low-confidence detections or records without positive FRP, and groups observations that are close in space and time. It could only publish a static snapshot labelled as an ATLAS-inferred entity; neither the browser nor a new Function would query FIRMS. Real execution remains pending a local FIRMS_MAP_KEY. |
| Copernicus GFM / GloFAS | GFM produces observed/derived-observed flood extent from Sentinel-1; GloFAS provides hydrological forecasts. | Not integrated. The queried STAC catalogue declares a proprietary license; its polygons are tile footprints and the observed extent is stored in GeoTIFF, so a correct territorial layer requires license clarification and server-side vectorisation/filtering. GloFAS forecasts must remain separate and be labelled as forecasts. |
| NASA LANCE MODIS/VIIRS Global Flood | Near-real-time global raster masks of observed water and flooding, distributed as tiles. | Not integrated: automated download requires Earthdata Login, the product does not supply a flood-episode entity, and turning GeoTIFF tiles into usable areas requires substantial local mosaicking, filtering and vectorisation. |
| NOAA VIIRS Global Flood Map | Observed global flood-water fraction in a daily 375 m product. | Not integrated: it is distributed as large NetCDF/TAR sets and does not provide consolidated episodes or vector geometries; its recurring transformation exceeds the volume and processing that are reasonable for this release's zero-cost static workflow. |
| UNOSAT flood products | Emergency-specific satellite flood analyses, often with downloadable geometries. | Not integrated: the catalogue is episodic rather than a uniform operational worldwide feed, and licensing and source-imagery terms must be verified for each individual product. |
| Other GDO / EDO indicators | CDI, soil moisture and agricultural impact risk, among other territorial indicators. | Not currently integrated. ATLAS uses only Meteorological Drought Tracking 2.0.0 as a separate territorial layer and does not reinterpret other indicators. |
| Smithsonian GVP | Global Weekly Report and documentary WFS for volcanoes and eruptions. | Not integrated: the published terms authorize personal, educational and other non-commercial uses and require prior permission for other uses. ATLAS does not presume broader reuse permission. |
| NOAA Tsunami Warning System | Official CAP/Atom advisories. | Not integrated directly because of CORS restrictions. ATLAS does not infer a tsunami from an earthquake. |
Hosting, privacy and artificial intelligence
ATLAS is published primarily as a static site and PWA on Netlify. The browser directly queries the identified external providers. Two serverless functions, with no secrets or database, complement the site: one compacts INPE's current KML for event selection and the other resolves the Open Graph metadata of shared links from official event identifiers. The sharing function does not participate in selection or transform the application's operational data. ATLAS does not expose private keys. The availability, frequency and terms of those services may change. Optional location is used locally once and is not displayed, stored or transmitted by ATLAS.
Generative artificial intelligence has supported development, language review and documentation. It does not decide in real time what is an emergency or generate events: the application applies deterministic adapters and rules to data from identified providers. Editorial and technical responsibility remains with the creator.
