A Dam Problem Solved

Lake Sarez, deep in the Pamir mountains of Tajikistan, was created only a century ago when a strong earthquake triggered a massive landslide. The area experiences considerable seismic activity, which could result in massive flooding downstream should a landslide dam break. With the help of 40 donkeys, 10 scientists and 30 staff from the National Time Service Center of the Chinese Academy of Sciences transported and installed a BeiDou-based deformation monitoring system at the dam. The team had to resolve technical problems in the rugged area, such as providing sufficient solar power and communications. With the system now operating, the dam is being monitored in real time down to the millimeter.

Photo: Geometer International

Geometer International, a Ukrainian developer of GNSS/RTK instruments and applications for satellite positioning, has introduced the Walker RTK, a dual-frequency L1, L2 RTK receiver in the compact form factor of a portable RTK device.

The Walker RTK is a lightweight, small-sized, affordable and full-featured device for collecting, storing and processing geo-referenced data on the survey site. According to the developer, a GNSS receiver in a convenient and affordable format will significantly expand the use of RTK technology. The new technology will be suited to most tasks requiring centimeter precision positioning and measurements in a 3D coordinate system.

Compact and lightweight, Walker RTK is the ideal solution for field workers working away from the office. The new device can be operated with just one hand, significantly improving the productivity of service personnel.

Possible applications for GNSS Walker RTK include surveying, utilities, solar power plant engineering, trenching and pipeline installation, drilling, forestry and municipal infrastructure control.

What’s under the bonnet of Walker RTK?

The Walker RTK is built around a 2-frequency L1/L2 184 channel board and a sensitive Helix antenna, satisfying up to 90% of basic user requirements. The tube-shaped housing geometry allows it to fit with any universal mount. The receiver weight is only 0.25g (0.470 with smartphone holder) due to the aluminum alloy housing with a protective coating. The Walker RTK has a built-in Li-Ion battery with enough power for 24 hours of continuous operation without additional recharging. The new energy-efficient architecture of the unit achieves this.

The GNSS receiver has the minimum amount of leading interfaces, resulting in high IP67 dust and waterproof rating. The device can be paired with a smartphone or tablet via Bluetooth, while connection via Bluetooth low energy is also planned for a future release.

Compatible with satellite systems

Walker RTK can track and determine geo-position using signals from all known existing satellite systems. This feature makes it possible to achieve the centimeter-level accuracy of an RTK solution within seconds.

GNSS signals processed by the Walker RTK GNSS receiver:

• GPS (L1C/A, L2C)
• GLONASS (L1OF, L2OF)
• GALILEO (E1B/C, E5b)
• BEIDOU (B1I, B2I)
• QZSS (L1C/A, L1S, L2C)
• SBAS (L1C/A)

Thanks to NMEA messaging, the Walker RTK GNSS receiver is fully compatible with any professional or freeware geolocation software, providing high accuracy and reliable RTK-corrected positioning.

Precisely GIS software used by UK police at G7 Summit

Precisely, a software company specializing in data integrity, announced that Devon and Cornwall Police leveraged its GIS software to enhance safety measures during the 2021 G7 Summit – an annual gathering of policy leaders from seven of the world’s major democracies.

The police force’s GIS team recognized that mapping software could play an important role to bring together data from a variety of sources and data formats, providing critical context in the assessment of safety protocols leading up to and throughout the Summit. The local force combined MapInfo Pro, a desktop mapping solution that provides location-based context from data, with third-party 3D visualizations to create a digital twin that enabled precise contingency planning. This model had an accuracy of up to five millimeters.

“We had two major hurdles we had to cross during the planning phase for the G7 Summit,” said Robert Goldsmith, GIS and Mapping Manager, Devon and Cornwall Police. “The first challenge was managing the sheer volume of security protocols needed for such a high-profile event, particularly given that the Summit was hosted in two locations. This meant that safety measures were required for different venues, as well as for each of the world leaders, as they traveled back and forth. The second was giving visibility to our security partners around the world, especially as the pandemic limited the ability for teams to travel to the site in the run-up to the event.”

Goldsmith and his team used MapInfo Pro to generate 2D gridded map books of the venues and enriched them with points of interest (POI) data, such as footbridges, cell masts, bus stops, and officer and partner locations. The team used aerial drone footage to build out an initial 3D model using capabilities provided by third-party providers. This was further augmented with 360-degree visualizations, using video footage that was captured by scanning more than 140,000 square meters of the Summit venues.

The resulting digital twin enabled Devon and Cornwall Police and their partners to anticipate security issues and create contingency plans using virtual reality headsets to remotely access locations during the planning phase. This removed the need to have more individuals on the ground than necessary in the run-up to the event, while still enabling highly accurate contingency planning to take place.

The G7 Summit went off without a security hitch, with GIS technology widely credited as being central to its success.

Mosaic debuts Mosaic X, compatible with REIGL mobile laser scanners

Photo: Mosaic

Mosaic, a geospatial imaging company, announced that its new Mosaic X high-resolution, spherical camera is now compatible with RIEGL’s mobile mapping systems.

The development of the Mosaic X focused on delivering a high-resolution, global-shutter, 360-degree camera with precise GNSS time stamping to achieve extreme visual clarity and accuracy at once. These qualities fit the requirements to be integrated with mobile laser scanning systems such as the RIEGL VMX, VMQ and VMY series.

Mobile mapping has uses across many industries and sectors, including private and public organizations. The two most consistent demands when mapping infrastructures are high-resolution, photo-realistic imagery and highly accurate data. Cameras such as the Mosaic 51 and Mosaic X capture road infrastructure with photo-realistic accuracy, which is more understandable to the human eye than a point cloud from a laser scanner.

“The pairing between 360-degree imaging systems and mobile laser scanning systems results in high precision LiDAR-based point clouds, colorized by photo-realistic images,” says Mosaic co-founder and VP of engineering, Rostislav Lisovy. “This outcome will then have the benefit of both a precise point cloud and panoramic images – for precise measurements and evaluation of textures.”

The push for sensor integration came from the customers, Mosaic CEO and co-founder Jeffrey Martin states. “We have had many requests from our customers who are looking to use RIEGL and Mosaic products in unison. The Mosaic X impresses with high-resolution panorama images and offers precisely time-stamped single-lens imagery for the purpose of point cloud coloring as well as the generation of undistorted, geo-referenced high-resolution imagery with 12 [megapixels] per lens.”

The RxLeverArm software tool aids integration of GNSS receivers that include inertial navigation systems (GNSS/INS). RxLeverArm is part of Septentrio’s RxTools software package included with every Septentrio GNSS/INS receiver. The new tool visualizes, validates and automatically calibrates the exact distance between the INS sensor and the antenna, removing the need for accurate distance measurements with complex instruments. For lever-arm compensation, users only need to measure the rough distance between the INS sensor and the main GNSS antenna reference points on the vehicle. Data is then logged under open-sky conditions, which allows the RxLeverArm tool to optimize the initial rough distance measurement and prevent common errors such as sign inversion.

How navigation data is used for video game development

News from OxTS

The possible applications for 3D point clouds are almost endless. When you think of lidar, the mind naturally wanders to applications of the autonomous vehicle navigation or geospatial survey type. In fact, navigation and lidar data are useful for all manner of applications—including video game development.

When a new technology, such as lidar, is first brought to market, a number of factors affect its price. Initially, the cost-per-unit is likely to be high to ensure recovery of research and development costs. However, as technology ages and manufacturers innovate and bring out new versions, price invariably comes down.

As this process occurs, it puts the technology into the hands of a much wider audience, increasing the number of new and innovative use cases.

Point clouds are useful for many wide and varied applications. Autonomous vehicle developers may use point clouds to aid object detection and avoidance, while geospatial surveyors could use a point cloud to determine road degradation over time or monitor the rate of coastal erosion.

These are however some of the more common use cases. But how can navigation data be used in applications such as video game development? Let’s first look at how navigation data works alongside lidar.

Lidar and Inertial Navigation

To create a 3D point cloud, users must combine the position, navigation and timing measurements from an inertial navigation system (INS) with raw lidar data. Without accurate INS data, it is impossible to create a point cloud. This is because the lidar sensor needs to know its position in space and time and its orientation.

To avoid complicated software engineering work, simple-to-use software such as OxTS Georeferencer is available to georeference the lidar data. Once georeferencing is complete, OxTS Georeferencer will create a PCAP file that users can view in many point cloud viewer software applications.

Enter Dronezone

As lidar technology becomes more accessible, new and inventive ways to use point clouds are coming to light. OxTS partner Dronezone is one such company finding new uses for lidar.

Dronezone builds and hires out professional unmanned aerial vehicles (UAVs). They build UAV payloads with Velodyne VLP-16 lidar sensors and OxTS INS devices they sell or rent to customers.

Cover: Kunos Simulazioni

Dronezone’s customers have used the payloads for a variety of projects. One used a payload to scan an aging railway bridge looking for possible weaknesses and deterioration over time. Besides geospatial mapping projects, Dronezone is seeing an increasing need to cater to niche applications.

Dronezone undertook surveying the Transylvania Motor Ring racetrack for a video-game developer Kunos Simulazioni, which publishes racing simulator “Assetto Corsa.” The company wanted an accurate digital representation of the track contours. The results, which you can see in the video and screenshots, are particularly impressive.

Racing Simulator

For this project, Dronezone moved away from traditional UAV-based mapping. To survey the track precisely, the company used the flexibility of its UAV payload by repurposing the hardware for use on a car. With many off-the-shelf solutions, this wouldn’t have been possible. The setup enabled Dronezone to complete multiple laps of the track and create a high-density point cloud.

“Using different components to build a UAV payload meant that Dronezone could reuse the hardware and build a different setup suitable for use on a car,” said Paris Austin, head of new product technology, OxTS. “It’s this flexibility that allows Dronezone to serve multiple applications.”

To further improve results, Dronezone used the Boresight Calibration feature within OxTS Georeferencer to calibrate the coordinate frames of the lidar sensor and INS. This process, which involves a short survey of two retro-reflective targets, increases the clarity of the final results and eliminates blurring and double vision.

The quality of the data produced has given Dronezone confidence it can win more business from the same customer to map further tracks for the game.

This is just one example of the new and unique applications we’re developing alongside our customers.

NGS will soon compute third multi-year CORS solution
On Aug. 5, the National Geodetic Survey (NGS) stated it will be updating the NOAA CORS to be aligned with the latest International Terrestrial Reference frame, ITRF2020 (see below). As stated in the announcement, NGS will soon compute a third multi-year continuously operating reference station (CORS) solution, MYCS3.

The last multi-year CORS solution, MYCS2, was performed by NGS in 2019. I discussed the MYCS2 in my February 2019 and April 2019 columns. This new multi-year CORS solution will be important to the 2022 modernized National Spatial Reference System (NSRS), because NGS will establish a strict mathematical relationship between the 2022 NSRS frames and the ITRF2020 frame. This will allow direct access to the NSRS (NOAA Technical Report NOS NGS 67).

NGS Aligns National System to Global Reference Frame

August 5, 2022

The International Global Navigation Satellite System (GNSS) Service, which provides GNSS data products globally, recently released a new GNSS-only version of the International Terrestrial Reference Frame. This provides GNSS users access to the reference frame through coordinate functions for a global set of reference stations. In response, NGS will soon compute the multi-year Continuously Operating Reference Station (CORS) Solution 3, which will modernize the National Spatial Reference System. Aligning the National Spatial Reference System with the updated global reference frame will allow greater access for the global community of scientists, educators, and commercial users of location science.

For more information, contact: Phillip McFarland

As in the past, the multi-year CORS solution will mean that the NOAA CORS coordinates will be updated to be consistent with the latest International Terrestrial Reference Frame of 2020 (ITRF2020). The International GNSS Service provides information about its GNSS products and services. Readers can find information on the latest International Terrestrial Reference Frame 2020 here. This column will provide basic information on the ITRF2020. Please note: NGS stated that it will soon start computing the third multi-year CORS solution, but — as of October — all NOAA CORS coordinates are still based on MYCS2 and provide coordinates in ITRF2014 epoch 2010.00 and NAD 83 (2011, MA11, PA11) epoch 2010.00. As in the past, NGS will provide advance notice before publishing the results of its third multi-year CORS solution.

A document on the ITRF website stated the ITRF2020 is expected to be an improved solution compared to the previous solution, ITRF2014. It listed several innovations introduced in the ITRF2020 processing.
Description from ITRF2020 Document

ITRF2020 is the new realization of the International Terrestrial Reference System. Following the procedure already used for previous ITRF solutions, the ITRF2020 uses as input data time series of station positions and Earth Orientation Parameters (EOPs) provided by the Technique Centers of the four space geodetic techniques (VLBI, SLR, GNSS and DORIS), as well as local ties at colocation sites. Based on completely reprocessed solutions of the four techniques, the ITRF2020 is expected to be an improved solution compared to ITF2014. A number of innovations were introduced in the ITRF2020 processing, including:
- The time series of the four techniques were stacked all together, adding local ties and equating station velocities and seasonal signals at colocation sites;
- Annual and semi-annual terms were estimated for stations of the 4 techniques with sufficient time spans;
- Post-Seismic Deformation (PSD) models for stations subject to major earthquakes were determined by fitting GNSS/IGS data. The PSD models were then applied to the 3 other technique time series at earthquake colocation sites.
The box below provides a good summary of the International Reference Frame and why it’s important to the scientific community as well as the surveying and mapping community. Readers can download the article from the June 2022 International GNSS Service Issue 4 newsletter. Users also can sign up to receive notices and newsletters from the International GNSS Service.

ITRF2020: A new release of the International Terrestrial Reference Frame By Zuheir Altamimi

What is the current rate of sea level rise in different regions of the globe? How does our Earth deform under the effect of plate tectonics, seismic phenomena, or the melting of ice caps? How the Earth’s center of mass is varying? How to determine the position of a point on the surface of a constantly deforming Earth and compare it to positions estimated decades apart? The answers to these fundamental questions for understanding the dynamics of our planet require the availability of a global, long-term stable terrestrial reference frame, but preferably a standard reference so to ensure interoperability and consistency of various measurements collected by sensors on the ground, or via artificial satellites. The International Terrestrial Reference Frame (ITRF) is the standard reference recommended by a number of international scientific organizations, including the International Union of Geodesy and Geophysics (IUGG) and the International Association of Geodesy (IAG) for earth science, satellite navigation and operational geodesy applications. The ITRF is an international effort that is built on the investments of space and mapping agencies, universities and research groups in operating geodetic observatories, archiving and analyzing the collected geodetic observations to derive not only the ITRF, but also critical geodetic products for science and society.

The ITRF integrates and unifies technique-specific reference frames provided by the four IAG’s international services of space geodetic technique (DORIS/IDS, GNSS/IGS, SLR/ILRS, VLBI/ IVS). It is supplied to the users in the form of temporal coordinates of more than 1500 stations, Earth Orientation Parameters, as well as parametric functions describing nonlinear station motions: seasonal signals due to mainly loading effects and post-seismic deformations for sites subject to major earthquakes. It is necessary to regularly update the ITRF (approximately every 5 years) in order to benefit from continuous observations so to improve its accuracy, considering station position temporal variations due to geophysical phenomena.

The ITRF is maintained by a research group at IGN-France and IPGP (Institut de Physique de Globe de Paris), and whose new release called ITRF2020 was published on April 15 and accessible here: https://itrf.ign.fr/en/solutions/ITRF2020. The ITRF2020 brings significant improvements compared to previous achievements: it confirms the estimate of the position of the center of mass of the Earth as it was determined in 2016, but also provides its seasonal variations; it improves the accuracy of the scale of the frame at the millimeter level, which represents a gain in precision of a factor of 8 on the measurement of the size of the Earth (compared to that determined in 2016); it provides a precise quantification of co- and post-seismic displacements caused by devastating earthquakes, such as that of Sumatra in 2004, Chile in 2010 and Japan in 2011. The IAG Services rely on the ITRF to align their geodetic products to it, and therefore disseminate it widely among the various users. In particular, using the IGS products, such as the orbits, allows a universal access in space and time to the ITRF.

As stated in the article by Zuheir Altamimi, ITRF2020 involves IAG’s international services of four space geodetic techniques: DORIS/IDS, GNSS/IGS, SLR/ILRS, VLBI/ IVS. Computing an International Terrestrial Frame is very complex and requires analyses of difference types of geodetic and geophysical data. It is beyond the scope of this column, but online is more detailed technical information.

For this column, I downloaded the station lists from the four space geodetic techniques and provided a few plots that depict the location and velocities of these sites. The box below depicts the location of the space geodetic techniques around the world. As indicated in the plot, some locations have more than one technique collocated at the same site.

Altamimi’s article on the ITRF2020 stated it is “necessary to regularly update the ITRF (approximately every 5 years) to account for station position temporal variations due to geophysical phenomena.” My February 2022 column discussed the tectonic plates and why is it necessary to account for movement in a geodetic reference frame. As I stated then, coordinates basically change because the Earth’s surface is moving due to the movement of major tectonic plates. See the box titled “What is Tectonic Shift?” for information about why it is called plate movement or tectonic shift. The world’s geodesists understand this and are attempting to manage the changing coordinates by providing a time-dependent component of the international terrestrial reference frame.

The box below depicts the horizontal velocities in the North America. These vectors look very similar to the velocities reported in my February 2022 column.

For a comparison to North America vectors, the box below depicts the velocity vectors in Europe.

Plot of the Horizontal Velocity Vectors in Europe based on the ITRF2020 Velocities

They are similar in magnitude, but not in direction. Once again, looking at the map of tectonic plates, North America is located mostly on the North American plate and Europe is on the Eurasian plate.

Australia is on the Indo-Australian plate and has some fairly large horizontal velocities vectors. See the box below.

So, what’s the difference between ITRF2014 and the new ITRF2020? The box below provides the 14 transformation parameters from ITRF2020 to ITRF2014. These transformation parameters have been estimated using 131 stations located at 105 sites. See the box “Plot of the Stations used in the Transformation Parameters from ITRF2020 to ITRF2014” for the location of these stations. Notice that the translation values in X,Y,Z are very small (<1.5 mm) between the two reference frames.

As previously stated, the third multi-year CORS solution will be important to the new 2022 modernized National Spatial Reference System (NSRS) because NGS will establish a strict mathematical relationship between the 2022 NSRS frames and the ITRF2020 frame. This will allow direct access to the NSRS, according to NOAA Technical Report NOS NGS 67. Again, there will not be any changes to NGS’s NOAA CORS coordinates due to ITRF2020 until NGS completes its third multi-year CORS solution.

Where have all the flowers gone? Mapping tool shows crop devastation of Ukraine war

Photo: Alter_photo/iStock/Getty Images Plus/Getty Images

Sunflowers — soniashnyk in Ukrainian — have been grown in Ukraine since the mid-18th century. Besides being a popular snack, growing the flower for export helps fuel Ukraine’s economy. Before the war, Ukraine and Russia supplied up to 80% of the world’s sunflower oil exports.

With the Russia invasion, however, sunflower and other crops have suffered, with growth of spring crops declining as much as 40% in the eastern Donbas region hit especially hard by the war.

OneSoil Map, by OneSoil, is a new, powerful data visualization and mapping tool that combines proprietary artificial intelligence (AI) with satellite imagery to map crops worldwide. It enables agricultural businesses to visualize massive datasets and deliver insights on a global scale. Another tool, the OneSoil application, helps farmers remotely monitor crop health, detect issues and apply fertilizers and seeds, increasing yields and boosting sustainable farming practices.

In Ukraine, satellite imagery and AI-based technologies are helping farmers face shortages and a population confronting food insecurity. OneSoil compared 2021 and 2022, and found the area used for the country’s spring crops — corn and sunflower — have decreased by 40% in wartorn regions, with the greatest decrease in Kharkiv (–59%), Donetsk (–58%), Luhansk (–57%) and Zaporizhia (–43%).

Corn is an export crop that accounts for 16% of the global market. OneSoil Map showed its overall acreage in the main corn production areas (Chernihiv, Poltava, Sumy) has dropped by 19% to 36%, depending on the region.

The above sample of sunflower crops in the Luhansk Oblast region — part of the wartor — shows the decrease in crop fields from 2021 (top, 1.5M acres). (Image: OneSoil)
