  • Surveyors, not the tools, define the profession

    Surveyors, not the tools, define the profession

    Many have debated how the surveying profession has morphed into something less than what our predecessors would have called surveying.

    In earlier times, the surveyor was an honored figure in the community and held in high regard, like the local doctor and clergy. Surveyors had the final word on boundaries and the limits of a family’s land holdings, so they were treated like royalty.

    Measuring devices were simple yet complicated enough for only the trained person to understand how boundary lines were determined. Surveyors during those times depended much on natural monumentation and terrestrial features; these items made for solid and definable boundaries. Measurements along these features were to be completed only by surveyors and their means of determining distances.

    Much has changed since those centuries past, including the reputation of the surveying profession. No longer are we mentioned in the same breath as doctors, clergy and lawyers. Even engineers are seen as “more professional” than surveyors. Many have debated how the surveying profession has been degraded from the noble status it once enjoyed and morphed into something less than what our predecessors would call surveying.

    There are many layers to each of the previously described professions, but they all have several things in common: each one relies on data collection, analysis, and professional opinion. Each of these steps requires a specific skill set that includes education and experience. Nowhere in this process does it allow for advancing technology to completely replace any of these steps.

    The evolution of technology and associated tools may help improve the profession, but it will not replace the knowledge necessary to be considered a true professional. Data collection within most professions is the biggest beneficiary of technology; surveying is a testament to these advancements. The breakdown, however, is the availability of the technology to the public and turning non-practitioners into low budget pseudo-surveyors.

    What makes us professionals

    Here is the abridged version of the definition of “professional” according to the Merriam-Webster Dictionary Online:

    professional (adjective)
    : of, relating to, or characteristic of a profession
    : engaged in one of the learned professions
    : characterized by or conforming to the technical or ethical standards of a profession
    professional (noun)
    : one who is professional
    : one who engages in a pursuit or activity professionally

    Similar professions have several examples of how the collection of data is a separate process and experience level from its analysis. Consider the following:

    MRI technicians train for their jobs through education, interning and experience. They know how to place patients within the equipment, shield them, apply the rays, and produce the scans as required by their job description. In simple terms, they are data collectors of patients’ medical conditions. Technicians do not analyze the scans nor offer any opinion on the prognoses of the patients. They are, however, relied upon to obtain the proper scans correctly and efficiently for review by doctors.

    Staff accountants or clerks are typically charged with data entry, maintaining ledgers and journals, and verifying data/entry accuracies. Often, clerks organize invoices, statements, and other receivables for input into clients’ accounts. Much of the work for this position is electronic and relies on the employees to be savvy with spreadsheets and able to import various data formats and spot suspect data. Once this work is completed, it become the responsibility of certified public accountants (CPAs) to review and certify the information. The key role here, however, is the accurate compilation of the accounting data.

    Paralegals play a key role in doing the heavy lifting of data collection for lawyers. Paralegals perform client and case research, interview witnesses, handle discovery of case information, and draft many of the documents needed by lawyers. They are tasked with assembling exhibits, delivering and filing necessary court documents, and helping with trial preparation. While they cannot express legal opinions on any case matter, it is the paralegals’ work that lawyers use to develop case strategies. Once again, the data collection is the key to the success of the lawyers’ work.

    Professional surveyors are no different from doctors, accountants, and lawyers in these examples. They rely on data collection obtained by experienced staff trained to operate sophisticated instruments and data collectors.

    Field technicians often serve as surveyors’ eyes, so specific training is necessary to ensure that they can accurately locate the required information. Technicians, however, cannot offer legal opinions on the location of land and parcel boundaries.

    This function is solely on the shoulders of land surveyors, who are licensed specifically in that jurisdiction to apply legal principles and case law to boundary issues.

    There is one in every crowd — the North Carolina lawsuit

    For those who are not paying attention, we are solidly in the 21st century and fully engulfed in the proliferation of geospatial data. Surveyors remain at the forefront of these technological advances with a plethora of tools and techniques being introduced on a regular basis.

    These tools and associated software are much advanced compared to their earlier surveying instrument counterparts, but through extensive programming and easy-to-use interfaces, this equipment may seem simple to use to the layperson. The elder surveying generation likes to refer to newer technicians as button pushers, because the users perform no true calculations.

    Yes, there are necessary checks and balances even with the new equipment, but the knowledge to operate these instruments is user-friendly and intuitive. So what happens when the technology is used by someone who is not a surveyor?

    Among the hazards of making these newer tools and software widely available is how they are used by the non-professional public. As many surveyors have already read about in the news and social media, a UAV operator in North Carolina has filed suit against the NC Board of Examiners for Engineers and Surveyors.

    The board previously ordered the operator to discontinue his UAV flights that engaged in mapping, surveying and photogrammetry services. The operator had been providing images to realtors and homeowners that depicted graphical lines representing property lines, but also included a disclaimer that the product was not intended for surveying purposes. The board ruled he was surveying without a license. The operator is now suing the board and accusing them of violating his First Amendment rights of free speech.

    This case is a high-tech example of what surveyors have faced in the past with overzealous owners of metal detectors. Many instances of low-budget outfits and even fence installers have been brought before state licensing boards because they misrepresented surveying services.

    It should also be noted that survey field crews who use their equipment during off hours to help family or friends with property location without their licensed supervisor’s knowledge face the same consequences. While the “corner finders” are somewhat harmless and get a slap on the wrist from licensing boards, it is the high-tech offenders who are creating much of the harm to the public.

    These situations with unlicensed surveying practices have greatly increased simply because of the available technology and low cost of entry. While GNSS receivers, robotic total stations, and associated data collectors are still quite expensive, new remote-sensing applications are being produced using consumer-grade equipment and advancing software. As technology continues to increase based upon miniaturization and capability, the costs also continue to decrease based upon volume of sales.

    Can I get that UAV in purple like my phone?

    Leading the charge into non-licensed use of new technology is the UAV and the new standard use of GPS technology within its guidance system of reasonably priced units. Hobby planes and helicopters have been around for years but required lots of skill and space to fly and were quite expensive. The invention of the multi-rotor UAV with integrated GPS has created an easy-to-fly vehicle with lots of capability.

    Couple this new vehicle with a high-resolution camera for photos and video; now it allows amateurs to be aerial cinematographers. Image storage space is not an issue due to increased SD card capacity and speed.

    A well-built UAV with all these capabilities is now very affordable and available everywhere. This revolution has led to larger format platforms with more rotors and heavier payloads for more sophisticated cameras and sensors. Once you have the photos and video, now you must do something with them.

    The advancement of software technology for processing photos, video, and remote sensing modules has become the hottest ticket in site modeling. The combination of the UAV’s capability and the software’s output enables trained pilots and software technicians to provide orthometric-based imagery. This imagery was previously completed by airplanes and cameras costing hundreds of thousands of dollars and processed by technicians on high-end computers using years of skill and experience.

    This entire operation can now be completed by one person with less than a $5,000 initial investment. This is a far cry from the funding needed in years past to outfit a survey vehicle with the necessary equipment and personnel to do this same project.

    Enter the FAA and new rules for flying unmanned aircraft. After much consideration, the FAA instituted guidelines for flying UAVs along with requiring a pilot’s certification to fly for commercial purposes. They also specified limits to UAV sizes and payloads, and limited flights to 400 feet above the ground.

    Many companies have purchased UAVs to provide aerial photos of their own facilities and projects, but fail to realize that publishing their images or videos qualifies them as a commercial user. Unfortunately, these regulations are much like driving a car without a license or insurance — it is only against the law if one is caught.

    The iPhone 12 Pro’s lidar scanner

     

    Another technology that will be catching on soon is lidar imagery from smartphones. The Apple iPhone 12 Pro and Pro Max contain sensors capable of capturing lidar data that is easily imported into computer drafting software. Several phone apps are also available for integrating this data into survey drawings. Geospatial data is literally at your fingertips.

    50 states, 50 rulebooks

    Rules and policies are put in place to regulate various professions and surveying is no different. The goal of these rules is simply to protect the public. Unlawful practice by non-licensed and/or non-qualified persons is a detriment to public safety.

    The question is often raised about professional surveying licensure and the ability to practice in multiple states. Each state differs in statutory rules regarding boundary surveys. The colonial states (and Texas) follow a metes-and-bounds standard while the remaining states generally adopt a PLSS rule. Local surveying methods, terrain challenges and early settlers often affected the statutes enacted by each state, therefore variations in licensing must be applied to applicants.

    However, the guiding principles for land surveyors remain the same in all states to protect the public. Boundary establishment and retracement is the sole responsibility of licensed land surveyors.

    The tools of the trade are a completely different matter. Controlling the surveying services would be easier if the equipment and supplies necessary to do the work were only available to licensees, but the free market will never let that happen. If a company has $30,000 and wants a robotic total station but has no surveying license, the dealer will not stop the sale. When we drop the price tag to an $800 UAV purchase for performing aerial photography, no one bats an eye. As the cost of equipment continues to fall, the number of unlicensed users will climb.

    ‘Men have become the tools of their tools’ (Henry David Thoreau)

    The point of this topic is that surveying is not about the tools necessary to complete the task. Surveyors carried out their work for thousands of years before electronic instruments and can continue to do so if they choose. The advancement of the equipment and the technology has made it easier for surveyors to do their work, but the true meaning of the task lies within the profession.

    Boundary analysis and determination is the responsibility of land surveyors. Data collection for that analysis can be completed by technicians using a variety of measuring tools. The team works together to complete the surveying process.

    Anyone can buy the tools; that, however, does not make them qualified to use them properly. It is not reasonable for one to buy a scalpel and offer brain surgery with a disclaimer. Ask any surveyor; there are some boundary retracements that are the equivalent of brain surgery. And we do not get to put a disclaimer on it.

  • British Army Light Dragoons demo anti-jam technology

    British Army Light Dragoons demo anti-jam technology

    NATO forces are deployed in some of the world’s most aggressive electronic-warfare (EW) environments. Intentional interference comes both from “personal protection” devices and large, high-powered EW assets.

    To navigate despite EW, armed forces need reliable and resilient GNSS/GPS positioning with anti-jam technology. The Light Dragoons — a light cavalry regiment of the British Army — are in a perfect position to test anti-jam technology for assured positioning, navigation and timing (A-PNT).

    The Light Dragoons were deployed as the United Kingdom’s Light Cavalry contribution to “Battlegroup Poland,” part of NATO’s enhanced Forward Presence. On the front line, the Light Cavalry engage in reconnaissance, mark targets for indirect fires, and prepare routes for the rest of the force. In this role, being prepared for EW is essential.

    To test A-PNT technologies, the Light Cavalry took part in Project Thundercat, a light cavalry capability investigation run by the Armoured Trials and Development Unit (ATDU). A Hexagon | NovAtel GPS anti-jam technology (GAJT) antenna, the GAJT-410ML, was fitted to a Jackal high-mobility transporter and integrated with its onboard positioning system.

    GAJT successfully defeats jamming on GPS L1 and L2 and Galileo E1 frequencies. When interference is detected, GAJT recognizes the unwanted interference and reduces reception in that direction. The result is a more resilient GNSS solution, protected measurements and A-PNT.

    The Light Dragoons found that GAJT successfully protected their positioning system despite experiencing interference. The GAJT-410ML antenna was easy to install in a simple plug-in-and-go process.

    In upcoming experiments, the British Army will use NovAtel technology to gain electronic situational-awareness data to characterize the radio frequency environment.

    GAJT systems are offered by NovAtel with customized offerings for land, marine and air applications.

  • Quantum positioning system could fill GPS gaps for aviation

    Quantum positioning system could fill GPS gaps for aviation

    The High-BIAS2 project advances cold-atom quantum gyroscope

    The High-BIAS2 (high-bandwidth inertial atom source) project today announced new milestones that move the industry closer to safer skies with more precise inflight navigation systems. The project has advanced its development of a cold atom-based quantum positioning system (QPS), which enables vehicle navigation without a GPS or GNSS signal.

    Reducing the reliance on GPS and GNSS technologies is critical for scenarios where signals from these systems are not available, such as underwater or in space, or when they suffer disruptions due to technical issues, cyberattacks and atmospheric or reflection effects.

    High-BIAS2 is designed to demonstrate the rapid commercialization of quantum technologies for real-world applications.


    “Inertial navigation systems enhanced by ColdQuanta’s Cold Atom Quantum Technology hold the promise of navigation in the absence of GPS and GNSS.”


    Inflight Trials. The project will culminate with inflight trials via BAE Systems’ test aircraft to validate the gyroscope’s use for aerospace applications. The airborne technology demonstrator will consist of a quantum gyroscope sensor and control system, reference gyroscope and commercial navigator system.

    “Gyro technology is a key aspect of navigation for airborne platforms. Improving performance whilst still being compatible with the aerospace environment is something that BAE Systems sees as important in aiding navigation when GNSS signals aren’t available,” said Julia Sutcliffe, air chief technologist, BAE Systems. “We can see exciting applications across our defense, security and commercial businesses including land, sea and air environments for the quantum devices being developed in the High-BIAS2 project.”

    UK Backing. High-BIAS2 is partially funded by the United Kingdom’s government through the National Quantum Technologies Programme, which is focused on accelerating the translation of quantum technologies into the marketplace and securing the UK’s status as a world leader in quantum science and technologies.

    High-BIAS2 is backed by UK quantum end users and supply-chain partners. Technology, application and commercialization development partners include:

    Cold atom quantum technology serves as the foundation for the project’s gyroscope and QPS. Its quantum sensor uses tightly confined ultra-cold atoms, which are cooled to a billionth of a degree above absolute zero and organized in a novel configuration. This approach to harnessing cold atom quantum technology is crucial to success in aerospace applications where motion sensing in highly dynamic environments is the norm.

    “High-BIAS2 is a huge step forward in developing practical use cases for quantum sensors and will showcase the real power of quantum in action,” said Dan Caruso, CEO and executive chairman of ColdQuanta. “Inertial navigation systems enhanced by ColdQuanta’s cold atom quantum technology hold the promise of navigation in the absence of GPS and GNSS. This technological breakthrough benefits a wide range of billion dollar industries including aerospace, autonomous vehicles, marine transportation, oil and gas excavation and more.”

    Image: Air Force Research Laboratory

    The NTS-3 experimental satellite will be launched in 2023, according to reports from C4ISRNET and Space News. The United States military will use the satellite for positioning, navigation and timing (PNT) as a supplement to GPS.

    The satellite was originally set to launch in 2022.

    The Air Force Research Laboratory (AFRL) plans to use the additional time to reduce risks and conduct more ground testing.

    Navigation Technology Satellite 3 will help guide future GPS satellites, a priority area for the military as the technology has become easier to spoof and jam. Among other features, NTS-3 will have steerable beams for regional coverage and a software-defined payload that can be reprogrammed on orbit.

    AFRL discussed the delay in a media roundtable held Wednesday, reports C4ISRNET. AFRL Commander Brig. Gen. Heather Pringle said that shift was out of the lab’s control since the satellite will launch as a rideshare with a U.S. Space Force payload, and that launch had been pushed back.

    AFRL plans to experiment with the satellite in geosynchronous orbit for one year, testing PNT signals and architectures as well as ground-based command and control systems and software-defined radios. Following testing, NTS-3 will transition to the U.S. Space Force and integrate into the service’s other PNT capabilities.

    In February 2020, L3Harris Technologies passed the NTS-3 project’s preliminary design review. L3Harris is the project’s prime contractor.

  • Emlid offers two PPK modules for cm-accurate drone mapping

    Emlid offers two PPK modules for cm-accurate drone mapping

    Reach M+ and M2. (Photo: Emlid)

    Emlid is offering two positioning modules for mapping with unmanned aerial vehicles (UAVs). Both the Reach M+ and Reach M2 provide centimeter-level accuracy in real-time kinematic (RTK) and post-processed kinematic (PPK) modes, enabling precise UAV mapping with fewer ground control points.

    The Reach M+ single-band receiver has a baseline up to 20 kilometers in PPK. The Reach M2 is a multi-band receiver with a baseline up to 100 kilometers in PPK.

    Usually autopilot triggers the camera and records the coordinate it has at that moment. When the drone is flying at 20 m/s and GPS works at 5 Hz, the UAV autopilot will have position readings only every four minutes, which is not suitable for precise georeferencing. In addition, there is always a delay between the trigger and the actual moment the photo is taken.

    Reach solves this problem by connecting directly to the camera’s hot-shoe port, which is synced with the shutter. The time and coordinates of each photo are logged with a resolution of less than a microsecond. Reach captures flash sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory. This method allows ground control points to be used only to check accuracy.

    The Reach RS2. (Photo: Emlid)

    The Reach M2 PPK UAV mapping kit consist of the Reach M2 multi-band GNSS receiver onboard the aircraft that records the location of each photo at a frequency of 20 Hz. It is combined with the Reach RS2 GNSS multi-band receiver on the ground, drastically reducing the number of ground control points and simplifying the setup process on site, while maximizing the accuracy to centimeter levels even in remote areas.

    The M2 tracks GPS/QZSS (L1, L2), GLONASS (L1, L2), BeiDou (B1, B2), Galileo (E1, E5) and SBAS (L1C/A), and receives a fixed solution almost instantly.

  • Emcore SDI500/505 IMU receives non-ITAR status, company gets defense nods

    Emcore SDI500/505 IMU receives non-ITAR status, company gets defense nods

    The non-ITAR status greatly increases the marketability of the SDI500/SDI505 IMUs to international customers. Plus, Emcore releases new SDI170 IMU and is awarded defense contract.

    Emcore’s dual-use SDI500/SDI505 Revision F inertial measurement units (IMUs) have received a determination that they are not subject to the International Traffic in Arms Regulations (ITAR) administered by the U.S. Department of State. Emcore has likewise determined that its SDN500 inertial navigation system (INS) is not subject to ITAR.

    The determination of non-ITAR status is expected to dramatically increase the size of the market that Emcore can address with its quartz micro-electro-mechanical systems (QMEMs) IMU and INS devices.

    Ranked Top in Trade Study. The SDI500/505 IMU was ranked first in overall accuracy, reported Emcore, in a U.S. military-commissioned trade study of 19 IMUs being evaluated as an alternative to the Honeywell HG1700 for various weapons systems.

    The objective of the third-party independent study was to deliver a comprehensive report to the government and make a recommendation supported by clear and compelling technical, financial, and other relevant data collected regarding the most advantageous IMU products and services available in the market today. 19 IMUs of various technologies, complexity, cost, and developmental status, from leading manufacturers, were evaluated in short and long flyout simulations against the HG1700.

    The dual-use non-ITAR SDI500/505 IMUs are designed to achieve the demanding performance levels required in sophisticated systems, including weapons guidance and targeting, commercial and defense fixed-wing aircraft and helicopters, unmanned autonomous vehicles (UAVs), and a wide variety of other high-precision commercial, industrial, marine, defense and space applications. They leverage quartz MEMS technology to deliver angle random walk (ARW) values of 0.02°/√hr with 1°/hr bias stability.

    Defense Contract Award. In March, Emcore was awarded a development contract valued at $1.1 million by a major U.S. prime contractor to design and manufacture a high-end IMU for tactical intelligence and reconnaissance systems. The prototype phase has been successfully completed and as part of the contract in this follow-on phase, Emcore will deliver initial production units that will be used for proof of manufacturing and system level qualification.

    The custom IMU will be based on Emcore’s proprietary closed-loop fiber-optic gyro (FOG) technology that delivers proven CSWaP (cost, size, weight and power) and performance advantages over other FOGs and competing technologies. It is designed to deliver the highest level of performance in Emcore’s tactical IMU product line, exceeding Emcore’s EN-300. Emcore’s FOG IMU technology delivers ten times the bias performance of legacy systems in compact form-, fit- and function-compatible packages.

    New SDI170 IMU. Emcore also launched a replacement IMU. The new SDI170 quartz MEMS tactical-grade IMU is designed as a form-, fit- and function-compatible replacement for the HG1700-AG58 ring-laser gyroscope (RLG) IMU, but with superior overall performance, versatility and a significantly higher mean time between failures (MTBF) rating over ruggedized environments.

    The SDI170 IMU is suitable for continuous-use applications with no wear-out components and delivers highly linear accelerometer performance and longer life compared to the HG1700 IMU. It is not ITAR controlled and has completed extensive internal and external customer testing to confirm compatibility to replace legacy products.

    The unit is designed for a wide range of high-precision, integrated commercial and defense applications including aircraft Attitude Heading Reference Systems (AHRS), GPS-aided navigation, ground surveying, mobile mapping, ROVs, autonomous vehicles, tactical weapons, and stabilization platforms.

    Non-ITAR Determination. As a result of this Commodity Jurisdiction (CJ) determination concluded by the U.S. Department of State, EMCORE’s SDI500/SDI505 Revision F commercial off-the-shelf (COTS) offerings were confirmed to be subject to the Export Administration Regulations (EAR) administered by the Department of Commerce (DOC). EAR classification typically results in fewer export-related restrictions and requirements. For this reason, this CJ determination for the SDI500/SDI505 will greatly increase the marketability of these IMUs to international customers.

    The SDN500 is Emcore’s most advanced QMEMS INS/GPS tactical-grade system, combining the latest generation quartz gyros and accelerometers from the SDI500/SDI505, with high-speed signal processing and a 48-channel coarse/acquisition code GPS receiver into a powerful, tightly coupled guidance and navigation system.

    “We would like to thank the U.S. Department of State for its evaluation of our commodity jurisdiction request and conclusion that our dual-use SDI500/SDI505 IMUs are not subject to ITAR,” said David Hoyh, Emcore’s director of sales and marketing for navigation products. “The determination of EAR status under the DOC enables more customers worldwide to benefit from these important, high-precision Emcore products.”

    Adva has launched the OSA 5405-MB, a compact outdoor precision time protocol (PTP) grandmaster clock with multi-band GNSS receiver and integrated antenna.

    Part of the OSA 5405 series of smart synchronization devices for indoor or outdoor deployment, the OSA 5405-MB ensures timing accuracy by eliminating the impact of ionospheric delay variation. This empowers communication service providers and enterprises to deliver the nanosecond precision needed for 5G fronthaul and other emerging time-sensitive applications.

    The GNSS receiver and antenna enable the OSA 5405-MB to meet PRTC-B accuracy requirements (+/-40 nanosec0nds) even in challenging conditions. For the first time, the technology is available in an edge timing device with minimal footprint, helping operators achieve unprecedented accuracy and reliability as they roll out wide-spread small cell networks.

    “Our multi-band, multi-constellation GNSS receiver provides an extremely cost-efficient way to achieve PRTC-B UTC-traceable network timing with the levels of accuracy needed for next-generation use cases,” said Gil Biran, general manager, Oscilloquartz, Adva. “By adding this technology to our versatile, small-form-factor OSA 5405 series, we’re offering a route to precision synchronization at the network access without significant investment.”

    “A ruggedized design and minimal visibility make our OSA 5405-MB easy to install in almost any outdoor location,” Biran said.  “With the power to compensate for ionospheric delay variations and resilience against jamming and spoofing, our compact edge solution really is the key to 5G synchronization.”

    The OSA 5405 series is a versatile timing solution for deployment deep in urban canyons, where advanced end applications require stringent synchronization. With its small form factor, the OSA 5405-I indoor variant can be positioned on windows to avoid multipath signal interference.

    Offering both electrical and optical interfaces and with cost-effective Ethernet cabling, the OSA 5405 series avoids RF feeds of traditional GNSS installations by integrating an antenna, receiver and PTP grandmaster in a single device.

    Ionospheric Delays. With multi-band GNSS technology, the OSA 5405-MB also protects against timing inaccuracies caused by ionospheric disturbance. By receiving GNSS signals in two frequency bands and using the differences between them to calculate and compensate for delay variation, the OSA 5405-MB eliminates inaccuracy and ensures ultra-precise synchronization whatever the space weather conditions.

    It can work with up to four GNSS constellations concurrently (GPS, Galileo, GLONASS and BeiDou), increasing the number of observable satellites in urban canyons. A comprehensive set of Syncjack PTP and GNSS jamming and spoofing monitoring features in combination with Adva’s Ensemble Controller and Sync Director assures high synchronization quality and provides transparency for simple operation of large synchronization networks.

    The OSA 5405-MB also offers network-delivered timing backup to further mitigate GNSS vulnerabilities and make synchronization more robust and resilient.

  • Parrot partners with Rapid Imaging on live AR mapping

    Drone company Parrot is partnering with Rapid Imaging, a technology provider delivering geospatial augmented reality (AR) and situational awareness solutions to government and enterprise users.

    The partnership pairs Parrot ANAFI USA platform drones and the FreeFly SDK with Rapid Imaging’s SmartCam3D SDK, a geospatial augmented reality and situational awareness platform for unmanned aircraft systems.

    SmartCam3D overlays geospatial data such as street vectors, road names, points of interest, polygons and other pertinent map entities onto real-time, full-motion video (FMV) provided by ANAFI USA’s 4K HDR video, 32x zoom and live video streaming capabilities. This provides mission personnel with advanced situational awareness as they perform critical drone operations.

    SmartCam3D also allows end-users to interact with live drone video in the same ways they would a map display, such as dropping a pin to mark a location or geocoding a selection from the real-time video stream.

    These situational awareness capabilities provide opportunities across a variety of mission sets: airborne law enforcement, insurance, industrial inspections, natural disaster response, real estate and search-and-rescue operations.

    The SmartCam3D SDK is a turn-key solution for UAS platform providers seeking to enrich their offerings with geospatial augmented reality and situational awareness tools. Features include geospatial AR, allowing users to enjoy a “Google Maps” type experience but with live drone video as the background layer rather than a satellite image. Granular declutter options allow users to select the types of map entities displayed on their live video feed.

    Custom GIS data integration allows users to import their own geospatial data to display. Pin-dropping allows users to mark locations within the live video with AR annotations and communicate those locations to a map display.

    Also, forward- and reverse-geocoding allow professional drone pilots to designate a point in the video and immediately receive the geospatial data associated with that point (lat/long or address) or designate a location and mark the location with an AR annotation within the video display.

    Finally, cross-Cuing allowing end-users to simultaneously navigate a full-motion-video display and map display.

    “Leveraging Parrot ANAFI USA’s precise GPS coordinates and advanced flight features, SmartCam3D® provides first responders and military personnel with up-to-date geospatial AR overlays on live video, combining the benefits of both a 2D map display and a Full-Motion-Video display into a single operating picture.” said Jerome Bouvard, director of Strategic Partnerships, Parrot. “This new partnership will provide easy-to-comprehend data to better assist first responders into making quick and accurate decisions during high-stress missions.”

    All data captured through SmartCam3D during sensitive missions is secure, as Parrot drone users must opt-in to share flight data with Parrot’s secure to store footage. Parrot ANAFI USA also features secure digital (SD) card encryption, which ensures complete protection of photos and videos if the drone or the SD card is lost.

    The SmartCam3D SDK is available for Android, iOS, Linux, and Windows systems for use with ANAFI and ANAFI USA platform drones.

  • Sinkhole detection feature uses satellite data analysis

    In recent years, sinkholes have been occurring around the world. A new service offers a sinkhole detection prediction tool using satellite imagery analysis.

    Synspective Inc., a satellite data and analytic solution provider, has released a sinkhole detection feature that predicts ground sinking area.

    Sinkholes are often caused by human activities (underground tunneling, oil/gas pumping, underground coal drilling, groundwater pumping, etc.). When these sinkholes occur in residential areas, they can cause significant damage to buildings and sometimes even loss of life.

    The sinkhole detection function developed by Synspective is a unique prediction algorithm that uses data science and machine learning to combine and detect the characteristics of spatial and temporal variations. With this technology, it is possible to identify areas where sinkholes are likely to occur in advance, areas where cave-ins have occurred, and areas where cave-ins are in progress after they have occurred.

    This function will be implemented in Land Displacement Monitoring, a solution service announced in 2020 that analyzes ground deformation over a wide area using satellite data. The input data is automatically updated, and the platform handles the processing and analysis of the complex satellite imagery. Since it can be viewed in a web environment, it can be checked at any time from the office as well as from the field.

    This new service’s expected use is multifaceted — it can be applied in many land risk-management projects such as construction projects, airport maintenance projects, and subway development projects, among others.

    In addition, remote area/site surveying can be extremely relevant in disaster struck areas where human access is restricted or dangerous, or where social movement is restricted due to the COVID-19 virus impact.
