  • Fugro uses airborne RAMMS to acquire land and sea data

    Fugro has completed a landmark data acquisition campaign over the Turks and Caicos Islands, marking the first commercial success of its new Rapid Airborne Multibeam Mapping System (RAMMS).

    Working under contract to the United Kingdom Hydrographic Office (UKHO), the company acquired more than 7,400 square kilometers of integrated, high-resolution bathymetric, topographic and image data. The resulting deliverables will support updated nautical charts and coastal zone management activities in the region.

    Launched in August 2018, RAMMS is a highly efficient, next-generation airborne bathymetric mapping system that uses multibeam laser technology to deliver depth penetration and point densities, the company said. The compact sensor is deployed from small aircraft and can be integrated with other remote sensing technologies for simultaneous collection of multiple complementary datasets.

    For the Turks and Caicos project, this approach made it possible to acquire near-shore (bathymetry) and coastal (topography and imagery) data in a single deployment, producing a cost-effective solution and advancing Fugro’s sustainability goals by significantly reducing fuel consumption.

    “After years of development, it’s extremely gratifying to operate RAMMS commercially and to demonstrate to clients the value that this cutting-edge technology can bring,” said Mark MacDonald, Fugro Americas Marine Division hydrographic service line director.

    He pointed to the massive Turks and Caicos project as an example. “The system’s multibeam lidar capability allowed us to achieve point densities that otherwise would have required vessel-based surveys. With RAMMS, we were able to avoid that additional time and expense, and significantly reduce health and safety exposure.”

    Fugro is working on three additional RAMMS projects in the Americas region, one for UKHO in Belize, and two for the Canadian Hydrographic Society, in Quebec and Atlantic Canada. These projects are similar in scope to that of the Turks and Caicos project, combining bathymetry, topography and imagery for maximum value to clients, serving both navigation and coastal applications.

    Based on steady interest in RAMMS, Fugro and technology partner Areté Associates are building an additional system to meet anticipated contracting volumes in 2019.

    Fugro is also finalizing a cloud-processing capability, which will further improve client delivery by streamlining data review and approvals, and ultimately making data available for download-on-demand.

    Additionally, Fugro aims to operate the unmanned aerial vehicle-proven system autonomously in 2019, providing further operational efficiency gains and increasing access to remote project areas.

  • Lidar data fused for understanding of tropical forests

    A University of Queensland, Australia, environmental project fused data from terrestrial and UAV lidar collections to estimate forest biomass.

    Forest ecosystems contain more biomass than any other ecosystem. Estimating biomass — a critical endeavor to detect the health of ecosystems — can be difficult. Traditional methods can be destructive, such as harvesting trees to measure the weight of the different components.

    “We know that forest ecosystems contain more carbon biomass than any other above-ground ecosystem on the planet,” said Kim Calders, Ghent University, on the TERN website. TERN is Australia’s land ecosystem observatory, under the University of Queensland.

    It’s estimated that Australian forests store about 10 billion tonnes of carbon, but calculating an exact figure without cutting down trees is difficult. “Traditional methods of estimating aboveground biomass are based on volumes calculated from cut trees and expensive field measurements of tree diameter and height,” Calders said.

    Enter 3D-FOREST

    The three-year 3D-FOREST project is funded by the Belgian Federal Science Policy Office led by Calders and Hans Verbeeck from Ghent University, partnering with Harm Bartholomeus and Martin Herold from Wageningen University.

    Tracking progress towards meeting major global environmental agreements and targets, such as the United Nations’ Sustainable Development Goals and The Paris Agreement, require detailed accounts of carbon stocks and how they’re changing over time.

    To meet this need, the 3D-FOREST project is developing new on-ground remote sensing techniques to measure biomass and forest structure and validate global-scale satellite measurements.

    “The concept of the project is to capture data to create ‘virtual forests’ with high level detail,” Calders said. “The combination of ‘bottom-up’ terrestrial laser scanning (TLS) and ‘top-down’ UAV lidar data improves biomass estimates and knowledge on how we can upscale plot-based measurements to the landscape level.”

    Harvesting virtual forests

    Representatives of the 3D-FOREST team undertook terrestrial laser scanning and UAV lidar data collection at three TERN sites: the TERN Litchfield Savanna SuperSite in the Northern Territory; the TERN Robson Creek SuperSite and the affiliate TERN Daintree Rainforest SuperSite in Queensland.

    Back in the lab, virtual 3D forests created from the lidar data are then ‘virtually harvested’. Quantitative structure models (QSM) digitally weigh individual trees by calculating their volume and converting this to carbon mass.

    “These 3D structural metrics and biomass estimates allow us to scale-up the spatial patterns of tree structure and evenness from the 1-hectare plot scale to entire forests,” Calders said. “This information is crucial for more efficient forest management, but also for better understanding of the spatial variation of forest structure in ecosystem models.”

    Scaling up to global carbon budgets

    As Europe’s, America’s and India’s space agencies get ready to launch satellites to measure and map the planet’s forests in high-resolution 3D, the value of on-ground and UAV lidar data collected by Calders’ team at TERN sites is even more apparent.

    The data from 3D-FOREST will be used to calibrate, validate and improve the accuracy of global bio-geophysical satellite data delivered by space missions including the European Space Agency’s BIOMASS, NASA’s GEDI, and the joint Indian Space Research Organisation and NASA NISAR.

    “The ability for these space missions to scale-up estimates of forest biomass to the global carbon budget and monitor ecosystem disturbances is dependent on the high-quality ground reference measurements collected at ecosystem research infrastructure sites, including TERN’s,” Calders said. “The emerging methods and technologies for data collection, and the speed of their development, are truly exciting.”

    The field campaign was made possible thanks to collaborations with the CSIRO, James Cook University and the Australian Government Department of Environment and Energy.

  • Anti-jam antennas advance aboard army observation vehicles

    Anti-jam antennas advance aboard army observation vehicles

    NovAtel’s GPS Anti-Jam Technology (GAJT) now rides into battle and military exercises aboard the Canadian Army’s Artillery Observation Post Vehicles (OPV) that have been fitted with the GAJT‑710ML antenna.

    OPVs are highly mobile vehicles that perform observation, reconnaissance and patrolling missions, surveying and acquiring strategic targets and relaying instant, accurate target coordinates acquisition to artillery fire command systems. With their exposed position on the frontlines of the battlefield, OPVs can encounter severe GPS jamming aimed at crippling their capabilities. OPVs require reliable Position, Navigation and Timing (PNT) not only to safely and effectively navigate on the battlefield, but to provide reliable information to artillery in the rear.

    GAJT provides protection for GPS navigation and precise timing receivers from intentional jamming in electronic attacks, ensuring that the satellite signals necessary to compute position and time are always available.

    “GAJT allows us to have confidence that the position information from the GPS constellation is assured.” said Major Mike Moulton, the project manager in the Directorate of Land Communication Systems Program Management.

    NovAtel’s GAJT is a retrofittable system. A military-off-the-shelf (MOTS) product, it comes in versions suitable for land or sea applications and smaller platforms such as unmanned aerial vehicles (UAVs). The antenna works with an array of military and civil receivers, including the Army’s handheld Defense Advanced GPS Receiver (DAGR), other military receivers using SAASM and M-Code, and with civil receivers.

    “GAJT scrubs off unwanted signals. It differentiates between what we can recognize as a signal coming from a satellite and something anomalous, which could be interference or deliberate jamming,” explained Peter Soar, NovAtel’s Business Development Manager for defence. “GAJT does not contain a GPS receiver, but works with the receiver that’s already installed. So GAJT faithfully passes the good satellite signals to the receiver which then operates functions such as integrity monitoring in its normal way. GAJT is in use operationally and has been shipped to 16 allied nations around the globe.”

    GAJT is a null-forming antenna system that ensures that satellite signals necessary to compute position and time remain available. There is no need to replace the GPS receiver that’s already installed, as GAJT works with both civil and military receivers operating in the GPS L1 and L2 bands. It is ready for M-Code, is a non-ITAR product and is readily available to authorized customers.

    Trials with the Canadian Army’s testing unit validated the technology, maintaining access to the GPS signal in an adverse signal environment. It also gave NovAtel engineers a detailed unclassified report on the trial findings and recommendations. The feedback helped NovAtel modify GAJT into a stronger product. The GAJT-710ML antennas were delivered earlier this year, and the Army worked with General Dynamics Missions Systems Canada, the prime contractor for the mission systems on the OPV, to integrate the antenna aboard the vehicle.

    “GAJT is a Canadian success story. It is 100 percent produced in Canada and sourced from Canadian components. I think that the Directorate of Land Communication Systems Program Management have shown there is excellent technology in Canada that can be leveraged to meet the Army’s requirements in a very rapid manner,” added Moulton.

    This story uses some quotes that first appeared in “Out of a Jam,” an article by Chris Thatcher in Canadian Army Today.

  • Autotalks launches vehicle-to-everything chipset

    Graphic: Autotalks
    Graphic: Autotalks

    Israel-based Autotalks has launched what it calls a global V2X (vehicle-to-everything) chipset.

    The chipset supports both dedicated short-range communications (DSRC) and cellular vehicle-to-everything (C-V2X) technology — both allow vehicles to share their location and speed to help prevent accidents and improve the safety of autonomous driving systems, the company said.

    The chipset’s processor also could allow customers to switch between the two standards. It minimizes development, testing and certification efforts for a V2X system to be deployed anywhere via a software-defined toggle between the two V2X technologies.

    Two competing standards

    Automakers have announced intentions to equip their new car models with V2X technology. In recent years, V2X has diverged into two different solutions, DSRC and C-V2X.

    While DSRC-based V2X is deployed in the U.S., Europe and Japan, C-V2X is gaining momentum in other regions. Its fundamentally different architectures have made it difficult to harmonize a single global solution.

    Autotalks’ response is to equip its second-generation chipsets with C-V2X in addition to native support of DSRC.

    Autotalks’ deployment-ready, second-generation V2X chipset supports both DSRC and C-V2X direct communications (PC5 protocol) at the highest security level. According to the company, the chipset supports DSRC based on 802.11p/ITS-G5 standards and C-V2X based on 3GPP specifications.

    Autotalks said its chipsets were designed to meet V2X market requirements and standards, including security, environmental, quality, thermal and other requirements.

  • Farewell to the Golden Age of GPS

    Farewell to the Golden Age of GPS

    One remark in particular caught my eye as I read the press release précis of the European GNSS Agency’s 2018 GNSS User Technology Report. In point, “Today only around 30 percent of receivers use GPS only.”

    “What?!?” methought. Incredulously, I downloaded the 92-page document, so easily done at www.gsa.europa.eu, and scrutinized it closely. Surely the GPS-only installed base out there is wider, vaster and deeper (it’s certainly older!) than could have been overtaken already by the wave of multi-constellation devices.

    Yes, they are clearly the future. But is the past already gone? That golden age when GPS was all that anyone lived, positioned and navigated by — vanished into the mist?

    Only earlier this very year was I upgraded from an iPhone 3 to an 8, with Galileo onboard for the first time. “Hip, but by the skin of my teeth,” I breathed.

    Chart: GSA report
    Chart: GSA report

    In the fine print on page 20 of the report lay clarification for my consternation. “For the analysis, each device is weighted equally, regardless of whether it is a chipset or receiver and no matter what its sales volume is. The results should therefore be interpreted as the split of constellation support in manufacturers’ offerings, rather than what is in use by end users.”

    Of the roughly 500 chipsets and modules tallied by the GSA, 30 percent of those models are GPS-only. That’s a number of quite a different color. See the chart for fuller information.

    Better minds than this can take a stab at how many devices in the hands end users on this day are still GPS-only. I’d put it above 50 percent.

    The writing’s on the wall for the GPS-only artifact, but a good many of those veterans are still out there, working hard in the marketplace. Their reign as the majority may be limited, especially with the rising global tide of multi-constellation smartphones, but let’s honor them one last time before consigning them to the museum.

    The GSA’s report, by the way, is a remarkably good and valuable read. No one can know it all, but this slim volume packs a remarkable and essential density of key facts, trends, issues, markets and more.

  • J-Mate combines GNSS/terrestrial for accuracy

    J-Mate combines GNSS/terrestrial for accuracy

    Javad GNSS has taken the power of its Triumph system and expanded to ground-based measurement technologies (versus satellite-based positioning) with the J-Mate.

    The J-Mate is a new measurement module that combines conventional measurement via laser scanning and photographic imagery with the multi-constellation location accuracy of the Triumph-LS receiver.

    Unlike most conventional total stations, J-Mate does not contain optics for manual use. It does, however, utilize precision horizontal and vertical encoders for angular measurement while the high-definition camera and laser module combine to locate the USB-powered target for accurate measurements, the company said.

    The target rest on top of the receiver and lights up for better visibility to the camera and sensor. The lighting power comes through the USB cord connected to the receiver.

    Coupled with the onboard data collector screen of the Triumph-LS, operation of the module is done visually with the LS mounted on top of the module or remotely on the J-Pod pole used for GNSS data collection.

    Setup of the module for survey data collection can be accomplished by several different methods: Backsight, Resect or Astro-Seek.

    The Backsight method of station establishment, while following in the manner of traditional total stations, can be accomplished by several different methods utilizing the J-Mate and Triumph-LS.

    • The first option is to occupy a known station with pre-established horizontal and vertical values, and then proceed to orient the instrument to another known station.
    • The second option is using the Triumph-LS GNSS engines to establish a station coordinate value, perform the same procedure on the reference station, and use the J-Mate software to calculate backsight azimuth for orientation.
    • The last option is to use a combination of the known coordinates or collect GNSS-derived values for either station or backsight point and complete the station setup.

    The Resect method is utilized when occupied station cannot use GNSS-observed coordinate values but can view two or more stations with known values. Once the user has measured all the visible know stations, the data-collection software provides geometric precision analysis and a coordinate solution if tolerances are acceptable.

    The last method of orientation, Astro-Seek, can observe solar or lunar positions to accurately determine the location and orientation of the station. The user installs a darkening filter for solar observations and starts the Astro-Seek process; the module automatically makes necessary remaining measurements and calculations.

    The J-Mate system is equipped with system parameters that allows the user to customize a variety of settings, including minimum and maximum collection distance, windowing of project area, and edge definition tolerance to fine tune scanning small objects. Also definable within the window area is the scan spacing variable, used to minimize the number of data points where needed.

    According to Javad GNSS, the range of the J-Mate is rated at 100 meters (328 U.S. survey feet) using the Javad target and to most white surfaces, while the rating for darker surfaces is 50 meters (164 U.S. survey feet). Three precision vials are placed around the top for visual verification of levelness in addition to the electronic leveling mechanism, giving the user on-the-fly notification of any unstableness of the instrument.

    The J-Mate isn’t exclusively a data collection system, though; this module and software is also designed to be an efficient staking application. Taking advantage of robust servos and effective targeting system, this system performs dutifully for staking applications where accuracy and precision are required.

  • Volcanic GIS: Mapping and imaging the Kilauea eruption

    A number of geospatial companies played a key role in the government’s response to the Kilauea Volcano eruption. The volcano on the Big Island of Hawaii began erupting May 3, and while quiet for more than a week, it could resume erupting at any time.

    Mapping the flow. As a resident of Hawaii, Brennan O’Neill, Hawaiian branch manager of Frontier Precision, was in a unique position to offer support. Frontier Precision provided free access to technology and expertise to assist in mapping the lava flow.

    “I had to help out,” O’Neill said. “It was tearing at my soul. For a geologist, it’s even more powerful than that. The lava flow is like a living mass that has a mind of its own, creeping, glowing — an upside-down conveyor belt surging forward and burning everything in its path.”

    Through Frontier Precision, O’Neill offered high-tech mapping equipment, his own expertise, and the help of Nathan Stephenson, an applied geospatial engineer working in the company’s Denver office.

    “We used a combination of Trimble R10s and Trimble R8s to gather accurate data points on the ground,” Stephenson said.

    This thermal map shows the fissure system and lava flows as of 6 a.m. on Saturday, Aug. 11. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.

    The mapping team flew UAS drones over the flow to gather visual imagery data, matched it to the ground reference points, stitched the photos together and draped it over county maps. The process was repeated as often as needed — daily, and sometimes even hourly — to show the speed and direction of the flow.

    Stephenson isn’t new to mapping lava flows. As a graduate student at the University of Hawaii – Hilo, he worked on collecting data on the Pahoa eruption in 2014, and he’s seen advances in technology in just a few years.

    “One thing we have now that we didn’t have in 2014 was a thermal radiometric camera that helps us map more accurately at night and enables us to capture large heat signatures.”

    The collected data helps Hawaii Civil Defense and other agencies keep the public informed and safe, and in the long term it also contributes to the store of scientific knowledge about eruptions and lava flow behavior.

    Airborne lidar insights. Another technology that aids in volcano response is lidar. High-resolution lidar surveys help first responders, scientists and government agencies monitor Kilauea conditions and predict future lava flows.

    Independent geospatial data firm Quantum Spatial Inc. (QSI) has conducted high-resolution lidar surveys of areas surrounding the Kilauea volcano eruption in Hawaii.

    The emergency response effort was part of the U.S. Geological Survey’s (USGS) Rapid Response Imagery Products (RRIP) in support of the Kilauea’s 2018 East Rift Zone – Remote Sensing Acquisition Requirement.

    The USGS Hawaiian Volcano Observatory (HVO), along with emergency responders, government agencies and academics, will use the data to better understand the conditions and characteristics of the volcano, and help planners model potential lava flows, which may better predict and respond to future flows and enhance safety of residents.

    The QSI team, which included GEO1 and Windward Aviation, deployed within days to acquire high-resolution lidar at point densities averaging from 40 to 80 ppsm, with up to 150 ppsm in select areas and 100-mp digital imagery using a Riegl dual VUX-1 LR sensor pod equipped with ABGPS/IMU mounted on a Hughes 500D helicopter.

    The project required 11 missions over the course of six days, operating at times as low as 500 feet above the ground and above active flows and nearby erupting calderas. With a need for a quick turn around, QSI deployed an analyst with the flight crew to post process each mission within hours of collection.

    The data was uploaded to the Geospatial Repository and Data Management System (GRiD) interface, developed by the U.S. Army Corps of Engineers (USACE), where additional data products have been developed and provided to the response team that includes FEMA, Hawaii’s Emergency Operations Center (EOC) and the Hawaii County Civil Defense.

    After data collection, QSI measured topographic shifts during the processing by comparing new data with a 2011 lidar collection from the same area. Survey specialists and USGS experts confirmed within hours of processing QSI’s lidar data that areas within the site had shifted up to 1.5 meters east, 2 meters to the north and 1 meter in elevation.

    USGS scientists will continue to examine the new topographic data to better understand the nature of these shifts, and integrate it into lava flow models for more accurate predictive modeling.

    The eruption in action. Using small unmanned aerial systems (sUAS) together with air-quality sensors, advanced imaging tools and Esri’s spatial analytics and mapping, a team from the Center for Robot-Assisted Search and Rescue (CRASAR) provided real-time aerial views of the eruption.

    The five volunteers armed with drones, advanced sensor systems and GIS technologies joined the response effort May 14-19 at Kilauea Volcano Lower East Rift Zone to assist in tracking and predicting the ongoing volcanic eruption. The team supplemented the University of Hawaii Hilo’s (UHH) sUAS capabilities, allowing UHH sUAS operators to focus on geographical and volcanology.

    The CRASAR team identified a new fissure not visible from the ground, projected the lava flow rate during the night when manned helicopters were not allowed to fly, and provided ongoing data collection from new thermal sensors technology.

    After the project, CRASAR published lessons learned on its blog:

    • Night flights of UAVs are very effective.
    • Rotorcraft UAVs can effectively sample gas.
    • Rotorcraft UAVs with thermal sensors are very effective.
    • Rotorcraft UAVs provide a quick look at lava flow rates.
    • Plumes will interfere with photogrammetric mapping.
    • Hanger 360 (software) rapidly produced panoramas.

    During the six-day Leilani deployment, the CRASAR team flew 44 sUAS flights, including 16 at night, using DJI 200, 210, Inspire, and Mavic Pro drones. Esri’s Drone2Map for ArcGIS together with Hangar’s Enterprise Platform for 360-degree imaging enabled rapid 360-imaging for situational awareness.

    DJI’s new XT2 thermal sensor provided unprecedented drone-based air-quality monitoring. Video and data were shared with local first responders using FirstNet, the first high-speed, nationwide wireless broadband network dedicated to public safety.

    The CRASAR response marks the first known use of sUAS for emergency response to a volcanic eruption and first known use of sUAS for sampling air quality.

    The GIS mapping and imaging technologies responders used on the scene at Kilauea Volcano Lower East Rift Zone are available here.
