One of the main advantages of remote sensing is its ability to detect fires in near-real time and over large areas. Remote sensing sensors can capture various wavelengths of electromagnetic radiation, such as visible, infrared, thermal, or microwave, that can indicate the presence and intensity of fires. For example, thermal sensors can measure the heat emitted by fires, while infrared sensors can detect the smoke plumes. Remote sensing data can be processed and transmitted to fire agencies, emergency services, and the public, to alert them of fire locations and spread. Remote sensing can also complement other fire detection methods, such as human reports, ground sensors, or fire towers.

Early detection is a major factor in controlling Wildfire spread. The second factor is response to this. The infamous CampFire event in Paradise, California was first noticed at 6:30 but not reported to the local fire authorities until 8:20 am. Actual containment action came even later. Rapidly spreading Wildfires, such as the August 8 Lahaina, Maui, cause horrific loss of life and property. The lack of early detection and notification of the people affected are heart-breaking.

This is a wonderful use-case for Remote Sensing using Satellites, Aircraft, Drones, In-place ground sensors, etc. Space and aerial applications have been in practice for quite a while already and the availability, technology and ability to process and use the data quickly is improving. For example, manned aircraft are in the air during and after thunder storms and scan entire states in a flight looking for lightening strikes in many states. Thousands of enlarged fires are extinguished each year with this method. Drones are currently in used during and post active fire events to detect movement of fire line as well as flareups in areas that were thought extinguished. Thermal and SWIR sensors are the most common sensors currently

As we project the future 5 to 7 years from now, our objective is to deploy swarms of advanced drones equipped with TK-7 or PT-8DN technology from Overwatch Imaging across managed forests during high-risk seasons. These drones will adeptly detect potential wildfire threats and promptly dispatch First Responder units to address emerging situations. Leveraging a cloud-based API, our aim is to provide nearly real-time access to First Responders, enabling them to monitor & proactively manage potential hazards. Our operational strategy involves dispersed pilots stationed in different states, overseeing drone rotation, fuel replenishment, and maintenance. This approach ensures the establishment of a robust & responsive wildfire management system.
Another benefit of remote sensing is its capacity to monitor the evolution and behavior of fires over time and space. Remote sensing data can provide information on fire size, shape, perimeter, direction, speed, and intensity, as well as environmental factors that influence fire activity, such as vegetation, fuel, moisture, wind, and topography. Remote sensing data can also be integrated with fire models and simulations, to forecast fire scenarios and outcomes. Remote sensing can help fire managers and responders to assess the fire situation, plan strategies, allocate resources, and evaluate risks.

Manned aircraft and long endurance drones are showing themselves very effective in fire monitoring during the night while the fire crews and equipment are resting. This data captured at night is made into a specific map formats for the fire crews early in the morning to understand where the fire is as they send out crews in the morning. TFR's are in place during fires, so the fire airspace manager is in charge of the airspace and these operations within the TFR are not FAA managed.

1/2: Agree with Daniel especially the long-enduring fixed-wing drones because copter drones typically suffer from speed and endurance. Manned-aircraft emmits lots of CO2e. For example, it's worth noting that a traditional DHC-2T aircraft consumes nearly 4,000 liters of fuel to provide reconnaissance over one million hectares (or 10,000 km2), resulting in an emission of ~9,885 kg (less than 10 tons) of Carbon Dioxide equivalent (CO2e). In stark contrast, a fixed-wing drone with fuel injection tractor propeller, produces a mere 21.5 kg of CO2e for the same area, significantly reducing its environmental footprint. A DHC-2T can't fly 30 hours straight and can't fly into smokes or at night. Satellite imaging qualities are coarse,

2/2: low resolution due to high altitude, have limited frequency, large volume datasets, slow processing, prone to cloud blockage and smokes, passing overhead once or twice a day, limited flexibility and availability, dependence on spectral radiance, reduced temperature tensitivity, conversion challenges and practical limitations, and expensive. According to LAND Info satellite images can go up to $34 US per square kilometer plus additional fees for post processing (i.e. GeoEye-1 satellite images cost $25 US/sq.km if minimum order quantity is met).

Remote sensing tracks wildfires by capturing infrared radiation, detecting heat sources, and monitoring smoke plumes via satellites like Landsat or Sentinel-2. Indicators include sudden increases in temperature in specific areas, visible flames, and the emergence of smoke columns. These anomalies, especially in vegetated regions, signal potential fire outbreaks. Remote sensing also identifies fire scars post-blaze, aiding in damage assessment and ecosystem recovery monitoring. Real-time observations facilitate timely intervention, enabling authorities to prioritize firefighting efforts, safeguard communities, and mitigate environmental impacts caused by wildfires.
A further advantage of remote sensing is its potential to map the extent and severity of fire impacts on the landscape. Remote sensing data can reveal the spatial distribution and magnitude of fire effects, such as burned area, fire severity, vegetation change, soil erosion, carbon emissions, and biodiversity loss. Remote sensing data can also be used to compare pre- and post-fire conditions, to measure the recovery and resilience of ecosystems. Remote sensing can support fire assessment and restoration, by providing data for damage estimation, compensation, mitigation, and rehabilitation.

With our fixed-wing drones equipped with Overwatch Imaging sensors, fire mapping is a click away. We focus on early detection of hotspots as small as 10'x10', providing real-time heat detection displayed on a user interface with geolocated imagery layered over Google Earth terrain maps. Within 5min, a mosaic is generated, stitching image data in-flight to create a single, multispectral composite. 10min, Fire Mapper outputs are generated, processing image data to produce a transfer-optimized map with vector point polygons delineating fire boundaries and heat intensity. Within 15min, a publication-ready map is created by operators using Overwatch and GIS tools, ensuring accuracy and transfer to the ground within 1/2hr of the initial fly-over.

Due to the SWIR being sensitive to surface and canopy moisture, the addition of this spectral band on sensors such as Landsat and Sentinel-2 make these useful sensors for fire scar mapping, aided by the fact that this band range is less sensitive to small particles (smoke plumes). There is also a correlation between spectral change and burn severity, however this can be saturated and is dependent on accurate baselining. As with all multispectral analysis, this is dependent on cloud and haze. There are applications of SAR to fire mapping, however this is not as straightforward and requires more expert guidance.
A further benefit of remote sensing is its possibility to predict the occurrence and susceptibility of fires in the future. Remote sensing data can help identify and quantify the drivers and indicators of fire risk, such as climate variability, drought, temperature, precipitation, lightning, vegetation type, fuel load, land cover, and human activities. Remote sensing data can also be used to create and update fire danger rating systems, that classify the fire potential based on weather, fuel, and fire history. Remote sensing can assist fire prevention and preparedness, by providing data for fire hazard mapping, early warning, education, and regulation.

Wildfires can be predicted by monitoring vegetation health, moisture content, and thermal anomalies. Indices like NDVI analyze vegetation vigor and dryness, crucial for fire risk evaluation. Thermal infrared sensors detect temperature changes, identifying hotspots in drought-affected areas prone to ignition. Additionally, monitoring weather patterns, terrain characteristics, and historical fire data aids in predictive modeling. Integrating these factors through satellites like Landsat or Sentinel-2 enables the creation of fire risk maps, helping authorities anticipate fire-prone regions. This proactive approach enhances preparedness, allowing for preemptive measures to mitigate potential wildfire outbreaks.
A final advantage of remote sensing is its role in fire prevention and mitigation. Remote sensing data can help design and implement fire management practices, such as prescribed burning, fuel reduction, fire breaks, and landscape planning. Remote sensing data can also help monitor and evaluate the effectiveness and impacts of these practices, by measuring changes in fire behavior, fuel characteristics, vegetation structure, and ecosystem services. Remote sensing can contribute to fire conservation and sustainability, by providing data for fire ecology, biodiversity, and carbon management.
