Fire data is available for download or can be viewed through a map interface. All maps are not to scale and for illustrative purpose only.
The red dot icon represents a hotspot detected in the last 12 hours.
Fire map hotspot. There are two major types of current fire information. Reprocessed satellite data will be availed at a later timing. The colour of the icon does not indicate the severity of a fire.
We ultimately decided on providing the hotspot deliverables in 2 ways. The hotspots depicted in the map are derived from the noaa satellite and they represent locations with possible active fires. Other icons show hotspots detected 12 to 72 hours ago.
Nasa lance fire information for resource management system provides near real time active fire data from modis and viirs to meet the needs of firefighters scientists and users interested in monitoring fires. This small file can be loaded into most gis software such as arcgis avenza maps google earth and handheld gps units. Satellites detect heat sources above a certain temperature.
These data are used to make highly accurate perimeter maps for firefighters and other emergency personnel but are generally updated only once every 12 hours. While hotspots do not always indicate a fire they provide accurate information about the locations and directions of possible fires and fire risk. Hotspots may go undetected due to cloudy conditions or partial satellite pass.
Fire perimeter data are generally collected by a combination of aerial sensors and on the ground information. For low cost sensor data a correction equation is also applied to mitigate bias in the sensor data. Fire perimeter and hot spot data.
The hotspot map updates every 2 to 4 hours depending on satellite availability. The fire and smoke map shows fine particulate 2 5 micron pm 2 5 pollution data obtained from air quality monitors and sensors information is shown on both the epa s air quality index scale using the nowcast aqi algorithm and also as hourly pm 2 5 concentration values. This map contains live feed sources for us current wildfire locations and perimeters viirs and modis hot spots wildfire conditions red flag warnings and wildfire potential each of these layers provides insight into where a fire is located its intensity and the surrounding areas susceptibility to wildfire.
Managing fire risk using data from satellites we worked with the department of defence and geoscience australia to develop sentinel hotspots a web based platform that enables users to identify the. Many bc fire personnel used the avenza maps app due to the ability to upload a custom basemap. Each viirs active fire thermal hotspot location represents the center of a 375m pixel.
Download active fire products from the moderate resolution imaging spectroradiometer and visible infrared imaging radiometer suite 375 m vnp14imgtdl nrt and vj114imgtdl nrt for the last 24 48 hours and 7 days in shapefile kml wms or text file formats viirs data complement modis fire detections but the improved spatial resolution of the 375 m data provides a greater response over fires. 1 a kml file containing the hot spots locations. The viirs data complement the modis fire detections but the improved spatial resolution of the 375 m data provides a greater response of fires over relatively small areas and has improved nighttime performance read more on viirs active fire products.
