TL;DR: The map above shows NASA FIRMS active fire detections from VIIRS (375m, ~12h latency, 3 satellites) and MODIS (1km, ~1-2 day latency, 2 satellites), served via NASA GIBS WMS — free, no login, no API key, with historical dates back to 2000. For burn-scar mapping (NBR), imagery overlays, and continuous area monitoring, open the full workspace.

5 Satellites

VIIRS on Suomi NPP, NOAA-20, NOAA-21 plus MODIS on Terra and Aqua for near-continuous global coverage.

Near Real-Time

VIIRS fire detections available within ~12 hours of satellite overpass. Track active wildfires as they develop.

No API Key Required

Available Sensors

VIIRS (Recommended)

375m I-band resolution. Available on S-NPP (2012+), NOAA-20 (2018+), and NOAA-21 (2023+). Best for detecting smaller fires and recent events.

MODIS (Long-Term Record)

1km resolution from Terra (2000+) and Aqua (2002+). Longest continuous fire record available. Note: ~2-day processing delay for recent dates.

Applications

Wildfire Tracking

Monitor active fire fronts and track daily progression of wildfire events

Deforestation Fires

Detect illegal burning and agricultural fires in tropical forests

Disaster Response

Support evacuation planning and resource allocation during fire emergencies

How It Works

1

Choose Sensor & Date

On the map above, select VIIRS (375m) or MODIS (1km) and pick any date — today back to 2000.

2

Zoom Into a Region

Fire hotspots appear as colored dots. Red = high confidence, orange = nominal, yellow = low.

3

Track Progression

Step the date back and forth to follow how a fire front develops day by day.

Frequently Asked Questions

Can I use this fire map without an account?
Yes. The live map on this page is completely free and anonymous — no login, no API key, no usage limits. An account is only needed for deeper analysis such as burn scar mapping, imagery overlays, and continuous area monitoring.
What is NASA FIRMS?
NASA FIRMS (Fire Information for Resource Management System) distributes near real-time active fire data detected by VIIRS and MODIS thermal sensors on polar-orbiting satellites. Operated by NASA LANCE.
What is the difference between VIIRS and MODIS?
VIIRS detects fires at 375m resolution with ~12-hour latency from 3 satellites (Suomi NPP, NOAA-20, NOAA-21). MODIS detects at 1km resolution with ~1-2 day latency from Terra and Aqua satellites, but has a record going back to 2000.
Do I need an API key?
No. Off-Nadir Delta displays FIRMS data via NASA GIBS WMS, which is freely accessible without any API key or authentication.
How often is fire data updated?
VIIRS data is typically available within 12 hours of satellite overpass. MODIS has a longer processing pipeline of approximately 1-2 days.
What do the confidence levels mean?
Each fire detection is assigned a confidence level — High (red), Nominal (orange), or Low (yellow) — based on the thermal anomaly algorithm. High confidence detections are most reliable.
Can I view historical fire data?
Yes. Select any past date to view fire detections for that day. This is useful for tracking fire progression over time.
