AeroScope addresses safety, security and privacy concerns while protecting drone pilots
DJI has unveiled AeroScope, its new solution to identify and monitor airborne drones with existing technology that can address safety, security and privacy concerns.
AeroScope uses the existing communications link between a drone and its remote controller to broadcast identification information such as a registration or serial number, as well as basic telemetry, including location, altitude, speed and direction.
Police, security agencies, aviation authorities and other authorized parties can use an AeroScope receiver to monitor, analyze and act on that information. AeroScope has been installed at two international airports since April, and is continuing to test and evaluate its performance in other operational environments.
“As drones have become an everyday tool for professional and personal use, authorities want to be sure they can identify who is flying near sensitive locations or in ways that raise serious concerns,” said Brendan Schulman, DJI’s vice president for policy and legal affairs. “DJI AeroScope addresses that need for accountability with technology that is simple, reliable and affordable — and is available for deployment now.”
DJI demonstrated the system Oct. 12 in Brussels, Belgium, showing how an AeroScope receiver can immediately sense a drone as it powers on, then plot its location on a map while displaying a registration number. That number functions as the equivalent of a drone license plate, and authorities can use it to determine the registered owner of a drone that raises concerns.
In March 2017, in response to growing calls by governments worldwide for remote identification solutions, DJI released a white paper describing the benefits of such an approach to electronic identification for drones.
AeroScope works with all current models of DJI drones, which analysts estimate comprise more than two-thirds of the global civilian drone market. Since AeroScope transmits on a DJI drone’s existing communications link, it does not require new on-board equipment or modifications, or require extra steps or costs to be incurred by drone operators. Other drone manufacturers can configure their existing and future drones to transmit identification information in the same way.
Because AeroScope relies on drones directly broadcasting their information to local receivers, not on transmitting data to an internet-based service, it ensures most drone flights will not be automatically recorded in government databases, protecting the privacy interests of people and businesses that use drones. This approach also avoids substantial costs and complexities that would be involved in creating such databases and connecting drones to network systems.
This system is consistent with DJI’s problem-solving approach to drone regulation, which aims to strike a reasonable balance between authorities’ need to identify drones that raise concerns and drone pilots’ right to fly without pervasive surveillance.
DJI has led the industry with safety and security advances such as geofencing and sense-and-avoid technology, and believes the rapid pace of innovation provides the best means to address new policy concerns.
Drone identification settings will be included in DJI’s initial drone software to allow customers to choose the content of their own drone’s identification broadcast to match local expectations both before and after identification regulations are implemented in different jurisdictions.
To protect customers’ privacy, the AeroScope system will not automatically transmit any personally identifiable information until regulations or policies in the pilot’s jurisdiction require it.
“The rapid adoption of drones has created new concerns about safety, security and privacy, but those must be balanced against the incredible benefits that drones have already brought to society,” said Schulman. “Electronic drone identification, thoughtfully implemented, can help solve policy challenges, head off restrictive regulations, and provide accountability without being expensive or intrusive for drone pilots. DJI is proud to develop solutions that can help distribute drone benefits widely while also helping authorities keep the skies safe.”
Using live data from USGS and Waze, a new Esri interactive map visualizes active wildfire locations and traffic alerts for Northern California.
The map incorporates a new mapping technique to group traffic alerts at locations where there is a high density of alerts. This method enables faster and more effective visual analysis in areas where there are many alerts that would normally overlap.
Active fire data displays the locations of large fire incidents in Northern California. Data is provided by the U.S. Department of Agriculture Forest Service and The Geospatial Multi-Agency Coordination Group, and is intended to give near real-time understanding of the situation on the ground.
Location and status of active fires is updated throughout the day as new information is gathered by first responders.
Data from Waze is reported by users of Waze and updated every two minutes. This data, provided by Waze through the Connected Citizens Program, contains filtered data for affected area including system-generated traffic jams and user-reported traffic incidents (including jams, accidents, hazards, construction, potholes, roadkill, stopped vehicles, objects on road, and missing signs).
DigitalGlobe releases images of Northern California wildfires
DigitalGlobe has released high-resolution satellite images of the wildfires burning in Northern California. These wildfires have killed at least 21 people, destroyed at least 3,500 structures, and burned more than 115,000 acres.
The Oct. 10 images were collected using the Shortwave Infrared (SWIR) sensor on DigitalGlobe’s WorldView-3 satellite, which is uniquely able to pierce through the wildfire smoke to see where the fires are burning on the ground. For comparison, the ground and the fire line are completely obstructed by smoke in the natural color image of the same area (see the larger overview image on the first slide).
The Oct. 11 images were taken by DigitalGlobe’s GeoEye-1 satellite. Some of these are natural color, while others are shown in the Very Near Infrared (VNIR), where burned areas appear gray and black and healthy vegetation is red.
Additionally, DigitalGlobe has activated its Open Data Program, which provides imagery to support recovery efforts in the wake of large-scale natural disasters. Pre- and post-wildfire imagery of the affected areas are available to emergency responders on the Santa Rosa wildfires page.

Old Faithful is Yellowstone National Park’s most famous landmark. Millions of visitors come to the park every year to see the geyser erupt every 44 to 125 minutes. But despite Old Faithful’s fame, relatively little was known about the geologic anatomy of the structure and the fluid pathways that fuel the geyser below the surface. Until now.
University of Utah scientists have mapped the near-surface geology around Old Faithful, revealing the reservoir of heated water that feeds the geyser’s surface vent and how the ground shaking behaves in between eruptions. The map was made possible by a dense network of portable seismographs and by new seismic analysis techniques. The results are published in Geophysical Research Letters.

For Robert Smith, a long-time Yellowstone researcher and distinguished research professor of geology and geophysics, the study is the culmination of more than a decade of planning and comes as he celebrates his 60th year working in America’s first national park.
“Here’s the iconic geyser of Yellowstone,” Smith says. “It’s known around the world, but the complete geologic plumbing of Yellowstone’s Upper Geyser Basin has not been mapped nor have we studied how the timing of eruptions is related to precursor ground tremors before eruptions.”

Small seismometers
Old Faithful is an iconic example of a hydrothermal feature, and particularly of the features in Yellowstone National Park, which is underlain by two active magma reservoirs at depths of 5 to 40 km depth that provide heat to the overlying near-surface groundwater. In some places within Yellowstone, the hot water manifests itself in pools and springs. In others, it takes the form of explosive geysers.
Dozens of structures surround Old Faithful, including hotels, a gift shop and a visitor’s center. Some of these buildings, the Park Service has found, are built over thermal features that result in excessive heat beneath the built environment. As part of their plan to manage the Old Faithful area, the Park Service asked University of Utah scientists to conduct a geologic survey of the area around the geyser.
For years, study co-authors Jamie Farrell and Fan-Chi Lin, along with Smith, have worked to characterize the magma reservoirs deep beneath Yellowstone. Although geologists can use seismic data from large earthquakes to see features deep in the earth, the shallow subsurface geology of the park has remained a mystery, because mapping it out would require capturing everyday miniature ground movement and seismic energy on a much smaller scale. “We try to use continuous ground shaking produced by humans, cars, wind, water and Yellowstone’s hydrothermal boilings and convert it into our signal,” Lin says. “We can extract a useful signal from the ambient background ground vibration.”
To date, the University of Utah has placed 30 permanent seismometers around the park to record ground shaking and monitor for earthquakes and volcanic events. The cost of these seismometers, however, can easily exceed $10,000. Small seismometers, developed by FairfieldNodal for the oil and gas industry, reduce the cost to less than $2,000 per unit. They’re small white canisters about six inches high and are totally autonomous and self-contained. “You just take it out and stick it in the ground,” Smith says.
In 2015, with the new instruments, the Utah team deployed 133 seismometers in the Old Faithful and Geyser Hill areas for a two-week campaign.
The sensors picked up bursts of intense seismic tremors around Old Faithful, about 60 minutes long, separated by about 30 minutes of quiet. When Farrell presents these patterns, he often asks audiences at what point they think the eruption of Old Faithful takes place. Surprisingly, it’s not at the peak of shaking. It’s at the end, just before everything goes quiet again.
After an eruption, the geyser’s reservoir fills again with hot water, Farrell explains. “As that cavity fills up, you have a lot of hot pressurized bubbles,” he says. “When they come up, they cool off really rapidly and they collapse and implode.” The energy released by those implosions causes the tremors leading up to an eruption.
One scientist’s noise is another scientist’s signal
Typically, researchers create a seismic signal using an active source, such as swinging a hammer onto a metal plate on the ground or setting off an explosion. Lin and Wu developed the data analysis method that would help find useful signals among the seismic noise without disturbing the sensitive environment in the Upper Geyser Basin. Wu says she was able to use the hydrothermal features themselves as a seismic source, to study how seismic energy propagates by correlating signals recorded at the sensor close to a persistent source to other sensors. “It’s amazing that you can use the hydrothermal source to image the structure here,” she says.

When analyzing data from the seismic sensors, the researchers noticed that tremor signals from Old Faithful were not reaching the western boardwalk. Seismic waves extracted from another hydrothermal feature in the north slowed down and scattered significantly in nearly the same area suggesting somewhere west of Old Faithful was an underground feature that affects the seismic waves in an anomalous way. With a dense network of seismometers, the team could determine the shape, size, and location of the feature, which they believe is Old Faithful’s hydrothermal reservoir.
Wu estimates that the reservoir, a network of cracks and fractures through which water flows, has a diameter of around 200 meters, a little larger than the University of Utah’s Rice-Eccles Stadium, and can hold approximately 300,000 cubic meters of water, or more than 79 million gallons. By comparison, each eruption of Old Faithful releases around 30 m3 of water, or nearly 8,000 gallons. “Although it’s a rough estimation, we were surprised that it was so large,” Wu says.
Further work
The team is far from done answering questions about Yellowstone. They returned for another seismic survey in November 2016 and are planning their 2017 deployment, to begin after the park roads close for the winter. Wu is looking at how subsurface structure and hence the propagation of seismic waves can change with time. Farrell is using the team’s seismic data to produce even higher resolution subsurface images and predict how earthquake waves might reverberate through the region.
Smith is looking forward to conducting similar analysis in Norris Geyser Basin, the hottest geothermal area of the park. Lin says that the University of Utah’s research program in Yellowstone owes much to Smith’s decades-long relationship with the park, enabling new discoveries. “You need new techniques,” Lin says, “but also those long-term relationships.”

Drones are quickly becoming a staple of the maritime industry. In January, the European Maritime Safety Agency (EMSA) issued the largest ever civilian maritime drone contact, valued at €67 million.
Under the contract, drones will be used to assist with border control, search-and-rescue operations and monitoring of pollution, as well as the detection of illegal fishing and drug and people trafficking.
External Vessel Inspections. Big names in the maritime industry such as DNV-GL, Lloyds Register and Maersk have all shown strategic intent to revolutionize their operations by embracing drone technology, and many maritime operators are now following suit.
All ship owners know that traditional methods of external vessel inspection can be a costly affair. Now that high-definition, camera-equipped drones are widely available and affordable, it is becoming more common to use them for external vessel inspections to assess structural conditions. Identifying substantial corrosion, significant deformation, fractures, damage or other structural deterioration can be done quickly, easily and cost-effectively using drones.
Tank Inspections. The visual inspection of cargo tanks was traditionally performed by workers suspended on ropes to inspect the tank structure. The sheer size of modern-day vessels means that access methods including staging, rafting and climbing are often used by surveyors to access tanks.
In contrast, drone surveys require no human access to the tank and, since no access equipment is required, there are no setup costs, and inspections can be completed within a quicker timeframe.

Bathymetric Surveys. Accurate and reliable information on the features of water bodies and their shorelines is vital to navigational safety. Bathymetric surveys gather the information, which is then published for use on nautical charts. Rather than using a fixed-wing airplane or helicopter, bathymetric sensors developed for drones allow this type of survey to be carried out flexibly and at a fraction of the cost.
To operate effectively in the harsh maritime environment, the technology has been developed to withstand storm force wind and heavy rain, snow and salt spray.
As technology advances, so does the flight time available on drones, meaning more area can be covered in a quicker timeframe.
Floating Flare-Tip Inspections. Drone surveys typically exist to provide close visual and thermal inspections of high, live or difficult to access structures offshore, and there’s nothing more challenging to access than a flare tip, 70 meters above water, on a floating production facility.
Drone survey inspections for flare tips remove the need for a shutdown to inspect the flare and offer reduced costs compared to aerial surveys carried out by helicopter or plane.
Offshore Wind Energy. The wind energy sector is growing fast. Storm force winds, erosion, lightning strikes and even build-up of insects can have an impact on turbines, and blades need to be inspected for deterioration. Inspectors have traditionally had to scale the turbines with the help of ropes and cables.
The maritime surveying company Martek Marine uses a drone fleet designed for turbine-blade inspections onshore or offshore. Qualified and trained pilots quickly and accurately identify and assess faults.
Traditional surveying requires turbines to be offline for two hours up to a day, but Martek’s inspection process reduces this time to 45 minutes.
Following the inspection, the client can access the data through Martek’s secure, cloud-based asset management portal where they can download a detailed PDF report and access raw survey data.
Fully Autonomous Drones? Fully autonomous drones could be the next big thing for maritime surveying. The drones can be pre-loaded with a 3D model of the ship. This allows the drone to autonomously work its way around the vessel, stopping at points of interest to obtain detailed video or image data.
Advancing this further, a drone could be designed to create its own 3D map of the vessel before carrying out the survey independently.
