A major use of remote sensing data is to compare images of an area taken at different times and identify the changes it underwent. With a wealth of long-term satellite imagery in open use, detecting such changes manually would be time-consuming and most likely inaccurate.
To address this, EOS Data Analytics has introduced an automated Change Detection tool to its flagship product LandViewer, a cloud tool for satellite imagery search and analysis in today’s market.
Unlike the methods involving neural networks that identify changes in the previously extracted features, the change detection algorithm implemented by EOS is using a pixel-based strategy, meaning that changes between two raster multi-band images are mathematically calculated by subtracting the pixel values for one date from the pixel values of the same coordinates for another date.
This new signature feature is designed to automate a change detection task and deliver accurate results in fewer steps and in a fraction of the time needed for change detection in most image-processing software.

Applications from farming to environmental monitoring
One of the main goals set by EOS team was to make the complex process of change detection in remote sensing data equally accessible and easy for non-expert users coming from non-GIS industries.
With Land Viewer’s change detection tool, farmers can quickly identify the areas on their fields that were damaged by hail, storm or flooding. In forest management, satellite image detection of changes will come in handy for estimation of the burned areas following the wildfire and spotting the illegal logging or encroachment on forest lands.
Observing the rate and extent of climate changes occurring to the planet (such as polar ice melt, air and water pollution, natural habitat loss due to urban expansion) is an ongoing task of environmental scientists, who may now have it done online in a matter of minutes. By studying the differences between the past and present using the change detection tool and years of satellite data in Land Viewer, all these industries can also forecast future changes.
Top change detection use cases: Flood damage and deforestation
A picture is worth a thousand words, and the capabilities of satellite image change detection in Land Viewer can be best demonstrated on real-life examples.
Forests that still cover around a third of the world’s area are disappearing at an alarming rate, mostly due to human activities such as farming, mining, grazing of livestock, logging, and also the natural factors like wildfires. Instead of massive ground surveying of thousands of forest acres, a forestry technician can regularly monitor the forest safety with a pair of satellite images and the automated change detection based on NDVI (Normalized Difference Vegetation Index).
How does it work? NDVI is a known means of determining vegetation health. By comparing the satellite image of the intact forest with the recent one acquired after the trees were cut down, Land Viewer will detect the changes and generate a difference image highlighting the deforestation spots, which can further be downloaded by users in JPG, PNG or TIFF format. The surviving forest cover will have positive values, while the cleared areas will have negative ones and be shown in red hues indicating there’s no vegetation present.

Another widespread use case for change detection would be agricultural flood damage assessment, which is of most interest to crop growers and insurance companies. Whenever flooding has taken a heavy toll on your harvest, the damage can be quickly mapped and measured with the help of NDWI-based change detection algorithms.

How to run change detection in Land Viewer
There are two ways you can launch the tool and start finding differences on multi-temporal satellite images: by clicking the right menu icon “Analysis tools” or from the Comparison slider ‒ whichever is more convenient. Currently, change detection is performed on optical (passive) satellite data only; addition of the algorithms for active remote sensing data is scheduled for future updates.

On May 22, Lockheed Martin delivered the GPS III Contingency Operations (COps) software upgrade to the U.S. Air Force’s current GPS ground control system.
The upgrade will enable the Air Force to start commanding the new, next-generation GPS III satellites now coming off the production line and beginning to launch.
And the new GPS III satellites are coming. The first GPS III satellite launched in December 2018; the second GPS III shipped to Cape Canaveral in March for a July launch; and on May 17, the Air Force declared the third new GPS III “Available for Launch” next.
Ground System. The challenge was modernizing the current ground system — formally known as the GPS Architecture Evolution Plan Operational Control System (AEP OCS) — to fly the legacy constellation, as well as the new, modern GPS III satellites, until the next generation Operational Control System (OCX) Block 1, still in development, is delivered.
To address this, in 2016, the Air Force contracted Lockheed Martin to develop the GPS III COps program. Currently, the AEP OCS controls 31 GPS IIA, IIR, IIR-M and IIF satellites launched between 1993-2016. With the AEP OCS’ new GPS III COps upgrade, the Air Force will be able to command and control both the legacy satellites, as well the more powerful GPS III satellites.

“Positioning, Navigation and Timing is a critical mission for our nation and COps will allow the Air Force to gain early access to its new GPS III satellites,” said Johnathon Caldwell, Lockheed Martin’s vice president for Navigation Systems. “We just finished Final Qualification Testing and delivery on COps, and it will be integrated and installed on the AEP OCS over the summer. We look forward to the Air Force ‘flying’ a GPS constellation on the COps OCS which includes the new GPS III satellites, later this year.”
Meanwhile, the first GPS III space vehicle (GPS III SV01), launched in December 2018, is finishing up pre-operational on-orbit check-out. It continues to be controlled by OCX Block 0 software installed at Lockheed Martin’s GPS III Launch and Checkout Center at the company’s Denver facility. GPS III SV01 is expected to be “handed over” to the COps OCS later this year after the legacy constellation is moved over to the updated AEP OCS.
Lockheed Martin has sustained the AEP OCS since 2013. In November 2018, the company completed the AEP 7.5 upgrade — the largest architectural change in the systems history — replacing significant code, hardware and software to improve the system’s cybersecurity capabilities and positioning the Air Force to better operate in contested, degraded and operationally limited environments.
In December 2018, the Air Force awarded Lockheed Martin the GPS Control Segment Sustainment II (GCS II) contract to continue to further modernize and sustain the AEP OCS through 2025. In 2020, the AEP OCS is expected to receive the M-Code Early Use (MCEU) upgrade, which will allow control of M-code, an advanced, new signal designed to improve anti-jamming and anti-spoofing, as well as to increase secure access to military GPS signals for U.S. and allied armed forces.
Lockheed Martin is under contract to develop and build up to 32 GPS III/IIIF satellites. GPS III will deliver three times better accuracy and provide up to eight times improved anti-jamming capabilities. GPS III’s new L1C civil signal will make it the first GPS satellite to be interoperable with other international global navigation satellite systems. Additional “IIIF” capabilities, beginning at the 11th satellite, will include a fully digital navigation payload, Regional Military Protection, an accuracy-enhancing laser retroreflector array, and a Search & Rescue payload.
Aerial imagery business Nearmap has launched its new 3D product to streamline the way industries such as urban planning, architecture, construction, government and councils view and shape cities across Australia and the U.S.
The company is also previewing its groundbreaking artificial intelligence (AI) technology at its customer event Navig8.
Nearmap 3D allows customers to stream and export 3D imagery on demand at massive scale through its proprietary MapBrowser web application. Because the imagery is updated frequently, businesses can work with the most current information to make more informed decisions.
Nearmap’s new AI technology is turning millions of aerial images — captured over a decade and multiple times a year — into valuable datasets. The datasets can be used to more accurately and efficiently measure change and quantify attributes, such as solar panels, pools, roofs or construction sites.
Organizations ranging from small businesses to large companies and cities will be able to take advantage of AI-driven location intelligence.
“Product innovation is in our DNA. Everything we do has the customer at the core,” said Tony Agresta, executive vice president of product at Nearmap. “Our customers’ worlds are evolving every day. We need to keep innovating to continue to give our customers a competitive advantage through technology breakthroughs like the ones we are sharing today at Navig8.
“Nearmap 3D is the result of a significant investment in R&D, but also listening to our customers and what they need to transform the way they work,” Agresta said. “Accessing 3D imagery up to now has typically been an arduous, time-consuming and expensive process — but not anymore. This represents the single largest, most frequently updated footprint of 3D accessible through a browser. The ability to measure in 3D space, size up an area and then export Nearmap 3D for use in other platforms will transform the aerial imagery market.
“The AI technology that we’re working on will allow organizations to identify locations with specific attributes and in so doing, reduce site visits, generate more leads, and eliminate the time involved to inspect properties manually. Nearmap AI does the heavy lifting so you don’t have to,” Agresta said.

Instant access to 3D through MapBrowser
Nearmap is making 3D imagery accessible to anyone, in the same way it has with 2-D. While Nearmap has offered 3D imagery since 2017, this new iteration of the technology allows users to instantly stream 3D content at massive scale via its MapBrowser web application.
The lightweight platform offers customers an immersive 3D experience, allowing them to visualize cities in 3D from any direction, measure distances, and immediately export a custom area in a variety of 3D formats at unprecedented speed — the download time is a matter of minutes for most requirements and only a few hours for very large footprints.
“It’s like switching from DVDs to streaming services,” said Tom Celinski, executive vice president of technology and engineering at Nearmap. “Our camera technologies have been capturing 3D since 2017, but now our secret sauce is bringing it onto MapBrowser, allowing users to easily and instantly stream this content with many export options. Now users can visualize, measure, define a custom area, export our 3D and use it in their workflows with other commercial platforms and tools. We’re helping 3D experts and novices alike access reality like never before, and this is an important next step in our Reality as a Service journey.”
Nearmap 3D comes with an extensive library, covering more than 400,000 square kilometers. It is updated once a year and covers major urban areas in Australia and the U.S.
“We live in a 3D world, we think in 3D, and so we have to ensure that our products give the closest representation of reality as possible,” Celinski said. “That means businesses that rely on visualizing 3D content, like architects, for example, can now access up-to-date 3D models instantly and export them in just minutes. In a tender process, for example, that can be the difference between winning a new project or not. The opportunities for Nearmap 3D are endless.”

A living data set
Nearmap AI technology is the result of more than two years’ worth of research and development, and a team of close to 20 data scientists and machine learning engineers. The team, led by Dr. Michael Bewley, is using the petabytes of imagery that the business has captured over the past 10 years and turning it into a living dataset to accurately identify changes or quantify attributes from the Nearmap library of aerial imagery.
Nearmap has built highly accurate machine learning models and deployed them on a massive scale. The automated process, and the constantly learning engine, means that the AI technology can be applied to any new geography. Nearmap also applies the models to new surveys, generating fresh results with current imagery.
To date, Nearmap has performed analysis on over 1 million square kilometers of imagery across Australia and the U.S. (which constitutes about 80 million properties) and is performing more analysis every day. Nearmap is now inviting customers to take part in a beta program to experiment with various use cases.
“We don’t prescribe how our technologies or content can be used by our customers,” said Michael Bewley, director of AI systems at Nearmap. “Our solar customers could use the AI technology to easily identify where and when solar panels have been installed for maintenance jobs, to prospect new clients in an area where solar energy’s popularity is on the rise; or a government entity that previously had the arduous task of tracking swimming pools or construction in their jurisdictions will be able to do it automatically.”
“But this is the tip of the iceberg — we’re just getting started. This technology is going to profoundly change the way that cities are built,” Bewley said. “Our plans include delivering AI results in many forms, much the same way we deliver our imagery today.”
Both technologies will be presented at Nearmap’s flagship event, Navig8, in Perth on June 6, Melbourne on June 11 and Sydney on June 13.

Protection from jamming has emerged as the key concern of of both national and organizational/corporate infrastructures. The world abounds in bad actors, and systems based on GNSS signals are uniquely vulnerable. A basic component of any anti-jamming (AJ) strategy is a shielded antenna. An upcoming webinar, June 27, gives a primer and several advanced looks at developing such an antenna-based AJ campaign. Register here for the complimentary webinar.
Anti-jam antennas use techniques, such as nulling or beam-forming, to mitigate the effects of interfering signals. (Image: Orolia)
Controlled reception-pattern antennas (CRPAs) are advanced, multi-element antenna solutions that protect a GNSS/GPS receiver from jamming sources. When combined with antenna electronics, they form an anti-jam antenna system (AJAS). These systems utilize several available technologies and vary in the number of elements.
CRPAs will play an increasing role in the GPS/GNSS landscape. Initially developed in the military domain, they are now entering the civilian market and are poised to bring their benefits to the fields of aerospace, ground transportation, autonomous driving and others. Engineers working with GNSS systems that employ CRPAs and multi-element antennas need special test systems since they need to replicate very specific test conditions that are impossible with live signals.
These complex antenna systems require advanced GNSS simulation equipment in order to be designed and validated, as well as to test their performance. These test systems come in two forms — an anechoic chamber system used to test the CRPA antenna over the air, and a wavefront simulator used to test the antenna electronics with a direct cable connection.
