Drone flying at night detects spot fire

Firefighters were alerted, found it and put it out

In 2010 I wrote an article on Wildfire Today about the two military surplus Cobra helicopters the U.S. Forest Service operates. The ships are still with the agency and are used on fires when the electronic systems are working.

These “Firewatch Cobras” have infrared sensors that can detect heat from fires. There is video in the article in which the pilot directs firefighters on the ground to a hot spot near the line on the Jesusita fire near Santa Barbara on May 12, 2009. The heat source is so small that the firefighters walked past it and over it several times, but the pilot could easily see it using the infrared equipment.

That video was filmed during daylight hours. Eight years later we now have the ability to have an unmanned aerial vehicle with sophisticated sensors orbit continuously over a fire, day and night, for 18 to 20 hours depending on the weight of its payload. If an incident management team on a fire activates a couple of these using the recently awarded Call When Needed contract, firefighters can have greatly enhanced situational awareness with near real time video.

Insitu was one of four companies that won CWN contracts in May. On the Taylor Fire in southwest Oregon on August 5, firefighters requested that the company’s ScanEagle aircraft monitor an overnight burn operation they were conducting along a ridge top road. As it orbited in the darkness at 8,500 feet, the sensors and the pilot detected a spot fire about 100 feet outside the fireline in the “green” unburned area.

The pilot talked directly with firefighters in an engine, telling them where it was.

Engine 66 stop there, spot fire is out your passenger door, 100 feet.

As you can see in the video below, the firefighters, it looked like at least three of them, searched the area and found the spot fire, which they said was about one foot square.

Depending on your taste in music, you will either want to turn up the sound in the video, or turn it off. I doubt if there’s any middle ground. There is no narration, so you won’t miss anything with the sound off.


The ScanEagle was launched from and recovered within the Temporary Flight Restriction over the fire. It was flown beyond visual line of sight in accordance with the 2015 FAA/Department of the Interior Memorandum of Understanding.

This is not the first time a drone has detected a spot fire during conditions when most aircraft are unable to fly. In 2017 on the Umpqua North Fire Complex in Southern Oregon a drone found a spot fire when smoke reduced the visibility to only 100 feet, keeping all other aircraft on the ground.

We have often written about the Holy Grail of Wildland Firefighter Safety — knowing in real time the location of the fire and the location of personnel. Many assumed the location of the fire would be the most difficult obstacle to overcome. But apparently the technology, suitable and practical enough to be used on a wildfire, is on a CWN contract.  BOOM!

The location of firefighters can also be solved. The technology exists now. Many agencies are using various systems, especially metropolitan law enforcement and fire organizations, but the federal land management agencies and most of the larger state fire organizations are dragging their feet. Earlier this year CAL FIRE took a step in the right direction when they issued a contract to provide technology in 1,200 state-owned vehicles that will facilitate mission critical data communications over a variety of networks (broadband, narrowband and satellite). This will include tracking the location of firefighting vehicles, but probably not dismounted personnel.

Complex terrain is one of the difficulties in continuously tracking the location of resources on a wildland fire, but there are ways to get around this, including putting radio repeaters in drones, perhaps the same one that is tracking the fire.

One of these days, drones will be on automatic dispatch along with engines, crews, and other aircraft. I know — a lot of deconflicting of aircraft has to be worked out, but it WILL happen.

Colorado developing drone system to enhance situational awareness

The state of Colorado is working on a system that would use drones to provide live video of wildfires to wildland firefighters’ cell phones. The Center of Excellence for Advanced Technology Aerial Firefighting is beta testing a DVI Mavic drone that would push the real time video to firefighters using software developed by the military, Android Team Awareness Kit (ATAK).

The program has the capability of displaying data from tracking devices carried by soldiers, or firefighters, and identifying their location on a map, which in this case could also show the fire in real time.

If they are successful in developing and implementing a system that can provide to fire managers real time information about the location of a wildfire AND firefighting resources, it would achieve what we call the Holy Grail of Wildland Firefighter Safety — knowing those two elements of information.

The DJI Mavic can only stay in the air for 20 to 30 minutes before having to return to base to replace the battery. So this beta test is probably only a proof of concept attempt, perhaps leading to a more robust drone, rotor or fixed wing, that could stay in the air for a much longer period of time.

Colorado already has the ability to transmit near real time imagery of fires from their two MultiMission Aircraft, Pilatus PC12’s. They are integrated with the Colorado Wildfire Information System, a geospatial database that displays incident images and details to local fire managers through a web based application.

A new app to predict wildland fire behavior

Wildfire Analyst Pocket appTechnosylva has released a new free app for smart phones that can help predict fire behavior. It is called Wildfire Analyst Pocket and is available for Android phones. It will soon be on the Apple app store as well.

In a video filmed May 21, 2018, the president of the company, Joaquin Ramirez, introduces us to the app.

Technosylva is one of the companies that produce systems available now that could lead toward the Holy Grail of Wildland Firefighter Safety, tracking in real time the location of firefighters and a wildfire.

Legislation would provide “Holy Grail” for wildland firefighters

Senate Bill 2209 would enhance situational awareness for firefighters

Two U.S. Senators are co-sponsoring a bill that would enhance the safety and situational awareness of wildland firefighters. Senate Bill 2290 would be an important step toward what we have called the “Holy Grail of Firefighter Safety”. This concept would provide the real time location of a wildfire and the resources working on the incident. Too often fatalities have occurred when firefighters did not know where the fire was or overhead personnel were not aware of the position of firefighters who were endangered by the quickly spreading fire. Or both at the same time.

The legislation would require the Departments of Interior and Agriculture to jointly develop and operate “a tracking system to remotely locate the positions of fire resources assigned to Federal Type 1 Wildland Fire Incident Management Teams”.

A complimentary requirement in the bill is “unmanned aircraft systems to [supply] real-time maps, detect spot fires, assess fire behavior, develop tactical and strategic firefighting plans, position fire resources, and enhance firefighter safety”.

The sponsoring Senators are a Democrat and a Republican, Maria Cantwell (D-WA) and Cory Gardner (R-CO). Since the bill was introduced January 10, 2018 no further action has taken place and no additional Senators have signed on, so it appears there is not much momentum pushing it through the process.

Here are the first two paragraphs in a press release issued by Senator Gardner’s office:

Washington D.C. —U.S. Senators Cory Gardner (R-CO) and Maria Cantwell (D-WA) introduced the Wildfire Management Technology Advancement Act of 2017, a bill designed to bring firefighting agencies into the 21st century.

This bill will increase firefighter safety by requiring the Forest Service and the Department of the Interior to begin providing GPS locations for crews on wildfires and to begin using Unmanned Aircraft Systems to scout out and map wildfires in real-time. Wildfire Today refers to the simultaneous use of mapping aircraft and GPS locators as the ‘Holy Grail’ of firefighter safety.

It is nice to see that at least two Senators are thinking about firefighter safety.

Thanks and a tip of the hat go out to Bean.

CAL FIRE to procure mobile data systems with location tracking capability

The system will enhance situational awareness for 1,200 firefighting resources.

(Originally published at 10:50 a.m. MT February 15, 2018)

The California Department of Forestry and Fire Protection (CAL FIRE) has signed a contract to provide technology in 1,200 state-owned vehicles that will facilitate mission critical data communications over a variety of networks (broadband, narrowband and satellite).

Under the agreement, RadioMobile will provide a centralized location tracking application within a mobile data terminal solution. The system receives incident information, provides mapping, and enables vehicle operators to communicate via a touchscreen application interfacing with their computer aided dispatching (CAD) system. The company will also provide the equipment, services, and support needed to implement a statewide VHF mobile data system and integrate network switching between broadband/cellular, VHF and satellite for CAL FIRE mobile resources.

We have been an advocate for the Holy Grail of Wildland Firefighting, which is knowing the real time location of firefighters and the fire. This system will implement a portion of that, tracking the location of firefighting vehicles and other mobile equipment (but probably can’t track dismounted personnel). It will also have the capability of displaying a map, and when data is available it could show the location of the fire. For example, it could show a sketched-out hand drawn map of the fire, or live video from an air attack ship or drone orbiting 10,000 feet over the fire. And, importantly, it could indicate the location of all firefighting resources that have location tracking enabled.

When these functions are implemented, it will enhance the situational awareness of firefighters. Congratulations to CAL FIRE for taking a step to make their personnel just a little bit safer.

Field tests of tracking devices for firefighters

We have often advocated the Holy Grail of Wildland Firefighting, which is knowing the real time location of firefighters and the fire.

There are many different technologies and platforms for collecting and displaying data about the location of the fire, but the information collected has yet to become commonplace in the hands fireline supervisors on the ground.

A similar situation exists for tracking the location of firefighting resources — personnel and equipment. The technology has existed for years, but the “deciders” in the National and State capitals have not recognized its importance for providing situational awareness, so it is only being used in a few scattered areas.

The Colorado Center of Excellence for Advanced Technology Aerial Firefighting (yes, they are still using that name) recently evaluated and tested two consumer-level personal tracking devices, the SPOT Gen3® and the Garmin inReach® (formerly known as the DeLorme inReach).

The executive summary from their report is below. The full document can be downloaded HERE.


Executive Summary
Wildland firefighters frequently operate in remote areas and are often a significant distance away from their supervisors or other nearby units. Additionally, wildland firefighters typically communicate with voice radios operating in analog mode, which does not facilitate location tracking or other digital situational awareness. One technology proposed to overcome these limitations and provide GPS location tracking and messaging for firefighters is satellite messengers. The Center of Excellence for Advanced Technology Aerial Firefighting (CoE) was requested to conduct a study of these devices to analyze their utility for firefighters. This study illustrated the technical specifications of two consumer-grade satellite messengers, the SPOT Gen3® and the Garmin inReach® (formerly known as the DeLorme inReach), and provided information on service options and costs. The study also assessed the capabilities of the SOS feature common to both devices and employed field trials to evaluate the performance of the devices in various types of vegetation and terrain.

SPOT Gen3The CoE found that the SPOT device provides a one-way flow of information from the device user to others using predesignated email addresses, text messages, or website access. This device requires programming ahead of use to designate the time interval for location tracking, as well as the content of the three types of messages it can send. The inReach device provides a two-way flow of information, with others able to communicate with the device user via email, text message, or website.

The SPOT device successfully transmitted a test SOS message from a meadow with a clear view of the sky, which then led to the Colorado Division of Fire Prevention and Control Duty Officer being notified of the SOS within 3 minutes. The SOS testing scenario was on a prescribed pile burn under the control of the area interagency fire management unit and the plan was for the Duty Officer to contact the interagency dispatch center regarding the SOS and have them establish radio contact with the unit in distress. Unfortunately, the phone system at the dispatch center was down during the test and no notification could be made. The CoE recommends that for mission-critical applications like wildland fire, the SOS feature be tied directly into relevant computer-aided dispatch systems—a complex requirement for interagency centers that frequently host firefighters from off-unit and from a variety of agencies.

Garmin inReachTo determine the utility of the satellite messengers for personnel tracking, six field trials were conducted—two each in minimal, moderate, and heavy forest canopy. For each level of canopy, one test was conducted in rolling terrain and one in rugged terrain. These tests sought to establish the rate at which the location of a firefighter walking the perimeter of a simulated 100-acre fire with both devices set on a 5-minute tracking interval would be known to a supervisor watching in real-time via an Internet connection.

The CoE determined that both devices can transmit location information successfully with minimal delays when used under minimal and moderate forest canopies. However, under a heavy forest canopy the devices experienced difficulties. The SPOT device failed to transmit 20% of points and the inReach device took more than 5 minutes to transmit 50% of points (and during one test, failed to transmit 35% of points). The CoE recommends shortening the tracking interval when operating under heavy forest canopies to increase the odds of successful transmissions and cautions against relying solely on these devices to achieve situational awareness for firefighters operating under heavy forest canopies.
