PhotoRadar World Map: Live Flights, Fire Hotspots, Natural Events & More

PhotoRadar World has grown from a webcam and satellite tracker into a full live global intelligence surface. Four major new data layers have been added: real-time flight tracking, NASA wildfire detection, NASA natural event monitoring, and UNHCR displacement data. This guide walks through every new feature and how to use them effectively.

The Redesigned Sidebar

With nine active data layers, the previous flat sidebar became hard to navigate. The sidebar has been rebuilt using an accordion layout with six collapsible groups:

• Cameras — live webcams and traffic cameras, with country/category filters and search
• Sky & Space — ISS live tracking and satellite orbital presets
• Earth Events — earthquakes (USGS), fire hotspots (NASA FIRMS), and natural events (NASA EONET)
• Environment — weather grid, cloud overlay, day/night terminator, GDACS alerts
• Human Data — UNHCR global displacement choropleth
• Visual Mode — default, analyst, and other display modes

Opening one group collapses the others, keeping the interface clean even when all layers are active. Camera filters (country, category, search) now live inside the Cameras group and only appear when that group is expanded.

Live Flight Tracking (OpenSky Network)

The new Live Flights layer pulls real-time aircraft data from the OpenSky Network. Aircraft positions are shown as directional markers on the map, rotated to match their current heading.

What you can see

Click any aircraft to open a detail popup showing:

• Callsign and ICAO transponder code
• Current altitude (in feet) and vertical rate
• Ground speed (in knots) and true track heading
• Origin airport ICAO code
• Aircraft on-ground status

Clicking an aircraft also renders a dashed flight track line on the map, showing the recent path pulled from OpenSky's historical state data for that ICAO address.

Performance design

Flights are fetched only for the current map viewport — not globally. This keeps the layer fast even over dense airspace like Western Europe or the US East Coast. The layer refreshes every 15 seconds and pauses when the browser tab is hidden to avoid unnecessary API calls.

NASA FIRMS Fire Hotspots

The Fire Hotspots layer displays active fire detections from NASA FIRMS (Fire Information for Resource Management System). Data comes from the VIIRS sensor aboard the Suomi-NPP and NOAA-20 satellites, which provide near-real-time global fire detection with 375-meter resolution.

How it renders

Fire data is visualized in two complementary ways simultaneously:

• Heatmap layer — a smooth density overlay that shows fire concentration at a glance, especially useful when zoomed out to regional or continental scale.
• Point layer — individual hotspot markers that appear as you zoom in, each clickable for exact coordinates, detection time, and confidence level.

Like flights, fires are fetched viewport-by-viewport and refresh every 15 minutes. The data covers the last 24 hours of VIIRS detections.

Use case: wildfire monitoring

Enable Fire Hotspots together with webcams to get both the satellite detection and a live camera view of the same area. During major wildfire events, many regions have public road cameras or weather cams that can confirm visible smoke or flame even when official reports are delayed.

NASA EONET Natural Events

NASA EONET (Earth Observatory Natural Event Tracker) monitors significant natural events globally. The World Map shows active events as emoji-icon markers categorized by type:

• 🌋 Volcanoes — ongoing volcanic activity and eruptions
• 🌀 Tropical storms — active hurricanes, typhoons, and cyclones
• 🌊 Floods — significant flooding events
• 🔥 Wildfires — EONET-tracked fire events (distinct from FIRMS hotspots)
• 🧊 Sea ice — polar ice extent anomalies
• 💨 Dust and haze — large-scale dust storms and smoke plumes

Each event marker is clickable. The popup shows the event title, category, start date, and current status (open or closed). The layer refreshes every 10 minutes and is served through a Supabase Edge Function with in-memory caching to respect NASA's rate limits.

UNHCR Refugee and Displacement Data

The Human Data layer visualizes UNHCR 2023 displacement statistics as a country-level choropleth overlay. Countries are colored by total displacement figures using a logarithmic scale, so both small and large numbers remain legible at the same time.

Click any country to see the raw numbers: total refugees hosted, internally displaced persons (IDPs), and asylum seekers. The layer is fetched once when enabled and cached in memory for the session — no repeated API calls on map movement.

This layer is designed for journalists, researchers, and educators who need geographic context for humanitarian stories. It pairs well with the EONET natural events layer, since many displacement events are driven by or correlated with natural disasters.

Combining Layers for Maximum Context

The real power of World comes from stacking layers. Here are three combinations that work particularly well:

1. Wildfire intelligence stack

Enable Fire Hotspots + EONET Natural Events + Webcams. NASA FIRMS gives you the satellite-detected fire locations. EONET shows which are tracked as significant events. Webcams give you a ground-level view. Together, you get satellite, categorical, and visual confirmation in one viewport.

2. Breaking news stack

Enable Live Flights + Earthquakes + EONET + Webcams. When something happens in a region, you can see how flight traffic responds (diversions, groundings), what seismic or natural event context exists, and what live cameras in the area are showing right now. This is a fast first-pass for situational awareness before deeper investigation.

3. Humanitarian context stack

Enable UNHCR Refugees + EONET Natural Events + Earthquakes. This combination surfaces the intersection of natural hazards and human displacement — useful for understanding which populations are most exposed when a new event occurs.

Analyst Mode

Analyst mode is unchanged in its core function but now has access to all new layers. Append ?mode=analyst to the URL or select it from the Visual Mode accordion in the sidebar. The HUD coordinate readout, reduced visual clutter, and focused interface work equally well with flights, fires, and natural events active.

Performance and Data Architecture

Several engineering decisions ensure the new layers don't degrade performance:

• Viewport-based fetching — OpenSky flights and NASA FIRMS fires are only requested for the bounding box currently in view. Moving the map triggers a debounced re-fetch.
• Tab-aware polling — all polling intervals pause when the browser tab is hidden (via the visibilitychange API) and resume when the tab becomes active again.
• Edge Function caching — NASA FIRMS (15 min TTL), EONET (10 min TTL), and UNHCR (1 hour TTL) responses are cached in Supabase Edge Function memory to minimize outbound API calls.
• Lazy layer loading — each layer's data is only fetched the first time you toggle it on, not on page load.

Combine with Other PhotoRadar Tools

World is most powerful when paired with the rest of the PhotoRadar platform:

• AI Location Search — geolocate an image from a wildfire zone or flood region, then verify it against FIRMS hotspots and EONET events on the World Map.
• EXIF Viewer — extract GPS coordinates from a news photo, then drop into the World Map and check what events or cameras exist at that precise location.
• Reverse Image Search — identify where an image was shared online, then use World to cross-reference with live data layers for that location.
