AI model for satellite imagery analysis

Satellite imagery analysis is fast becoming a highly lucrative business model for both commercial players and defense contractors. Just last month, Airbus launched a new geospatial tool which would make planet-wide change detection possible in near-real-time. And now, Lockheed Martin has announced a satellite imagery recognition system which uses open-source deep learning libraries to identify and classify large datasets quickly.

Called Global Automated Target Recognition (GATR), the artificial intelligence model uses Maxar’s Geospatial Big Data platform to access the latter’s 100 petabyte treasure trove of satellite imagery library and millions of curated data labels. The Cloud-based system promises to save image analysts the trouble of spending countless hours manually categorizing and labeling items within an image.

During a public demo at GEOINT 2019 conference, GATR was able to search the entire state of Pennsylvania – 120,000 square kilometers – for fracking sites in only 2 hours. So, even if someone who is not an expert on oil production sites is looking for information on the same, they can leave the traditionally-manual process to GATR.

Lockheed Martin says the system can identify characteristics of an object area or target with an accuracy of over 90%. The self-learning model can recognize ships, airplanes, buildings, seaports, and many other commercial categories, freeing up analysts for higher-level tasks.

Mark Pritt, a senior fellow at Lockheed Martin and principal investigator for GATR, adds, “This system teaches itself the defining characteristics of an object, saving valuable time training an algorithm and ultimately letting an image analyst focus more on their mission.”

Lockheed Martin insists that it has an advantage over other players offering imagery analysis because its system uses commercial imagery from vendors like Maxar and Planet to ensure global coverage. “With our tool, the user can draw a box anywhere in the world and hit the button,” Pritt tells SpaceNews in an interview. “The system will go search for objects of interest such as fracking wells, airplanes or refugee camps.”

Helping farmers move from analog to digital farming with drones and remote sensing

The $5T global farming industry still relies on the observations of human scouts to determine crop conditions. This labor-intensive and error-prone method contributes to >50% over-application of costly and environmentally harmful inputs, missed indicators of emergent conditions that suppress yields, and a limited ability to forecast crop performance or optimize farming practices.

SlantRange solves the agricultural information problem with its patented technologies in low-altitude remote sensing and edge analytics; enabling more efficient, automated, and environmentally responsible farming through targeted crop measurement and data delivery.

We interviewed Matt Barre, Director of Strategic Development at SlantRange to learn more about their vision, their business and what makes them a successful remote sensing startup. Enjoy reading the interview 🙂


  1. Matt, SlantRange founder’s all have prior experience working in the defense sector building sensors for a totally different kind of drone. What made them take the leap of faith into entrepreneurship and start SlantRange?

Our two co-founders, Mike Ritter and Mike Milton, as well as myself and several other colleagues here at SlantRange, had been working together at General Atomics for almost a decade designing, testing, and deploying a variety of remote sensing and advanced analytics solutions for the Predator family of unmanned systems in defense applications. This included hyperspectral, multispectral, thermal, LIDAR, active/passive imaging systems as well as all of the data processing and visualization tools required to support these sensors.

About 6 years ago, Ritter and Milton saw the increasing trend of using drones for commercial applications as an excellent opportunity to apply their expertise in remote sensing and analytics to address a new market. While there were several verticals to explore, agriculture represented a massive market opportunity where this new technology could bring valuable new information and new levels of efficiency to tasks that were currently being conducted with manual labor.

They quickly developed a few prototypes and began testing them with a small network of corn and soybean growers in Nebraska. Those growers were immediately impressed, became the initial investors, and SlantRange was born.

  1. SlantRange’s main product is your multispectral sensor (backed by your suite of remote sensing analytics products). Multispectral sensors aren’t something new though. How is the SlantRange sensor different and better?

Indeed, multispectral sensing has been used in agriculture for quite some time, primarily from satellites. The various biochemical characteristics of plants that can be inferred from spectral signatures and indices are very well established. However, relatively recent advancements in camera technology have enabled these sensors to be small enough, light enough, and cheap enough to be practical for use on small low-altitude drones.

At SlantRange, we are strongly committed to the accuracy of our sensors as the value of the data products we produce are of course completely dependent on the accuracy of the raw data from our sensors. One example is our radiometric calibration, the process we use to normalize our measurements under changing sunlight conditions. Our sensors measure the amount of light that is reflected by a plant in multiple narrow spectral bands to derive various metrics about the health of the plant. But in order to do this accurately, we need to know the intensity and spectral content of the incident sunlight. We achieve this with our Ambient Illumination Sensor (AIS), which is mounted on top of the aircraft and measures the sunlight characteristics in real-time during the flight. These measurements are used to calibrate the reflectance measurements from the crop, producing completely normalized measurements that can be compared over time.

As an example, if you collect a map of a field without this sunlight calibration technique and then collect another map a week later and the crop looks different, you don’t know if the crop health has actually changed or if the differences are just due to different sunlight conditions. With our calibration technique, all of the measurements are on a normalized scale and can be accurately compared over time, allowing our customers to conduct more advanced analysis, such as evaluating trends, forecasting, etc.

We now have 3 issued patents on this calibration technique and we consider it a foundational technology for airborne imaging and analytics in agriculture.

  1. At a time when every single company out there is trying to get their application running on the cloud, SlantViewTM – your analytics platform is something that doesn’t even need the internet to work. Why is that?

Aerial imaging systems generate large volumes of data very quickly. Even when a high-speed internet connection is available, it can take quite a long time to upload the imagery for processing in the cloud. And within the agriculture sector, you simply can’t rely on the availability of an internet connection at all. So very early on, we decided to pursue an edge-compute architecture for our solutions. This includes some pre-processing that is completed on the sensor itself (each of our sensors include a Qualcomm Snapdragon processor) with the balance of the analytics completed in SlantViewTM, running completely offline on a laptop or tablet.

This edge-compute processing model has been at the core of our analytics engine since the beginning has been a big contributor to our market traction across the globe. We’re now operating in over 45 countries, including many locations that don’t have access to high-speed internet connections.

However, it’s important to note that we certainly appreciate the value and power of cloud-based analytics when a connection is available. We have integrated with several cloud-based farm management platforms that allow users to aggregate our data with other farm data such as soil data, weather data, and satellite data to establish more comprehensive insights about their operations.

We have also partnered with Microsoft to integrate their Azure IoT Edge services into our platform to seamlessly ingest, manage, and analyze data from large networks of distributed sensors. Custom analytics, as well as automated machine learning and artificial intelligence algorithms, can be deployed both in the cloud and at the edge with this new architecture.

  1. SlantRange has been working quite closely with DJI and recently you launched the 3PX sensor that is specifically meant for DJI drones. Could tell us more about the sensor and your partnership with DJI.

We announced our partnership with DJI in March of 2018 with the launch of our 3PX sensor. DJI approached us several months earlier to be a launch partner for their Payload SDK, which allows 3rd party payloads to integrate seamlessly with the DJI Matrice 200 Series drones, their workhorse platform for enterprise applications. The 3PX uses the DJI SKYPORT, a custom mounting interface, to mount directly to the drone just like any other DJI camera. The interface also provides power to the 3PX, eliminating the need for any external power cables or batteries to power the sensor. And most importantly, the interface includes a real-time data connection between the 3PX sensor and the operator on the ground, using the existing data link between the drone and controller.

You can learn more about the 3PX and our partnership with DJI in this webinar.

  1. As a company that counts farmers among your (angel) investors, I’d guess that convincing farmers of the benefits of remote sensing was the easy part. What has been your biggest engineering challenge in building sensors for drones?

Our biggest engineering challenges typically arise from the conscious decision we made very early on to not be involved with the drone hardware itself. Our expertise is in remote sensing and analytics so we chose to focus our efforts in these areas. However, this leaves us very dependent on the other hardware and software vendors in the drone ecosystem. Our users have a wide variety of applications and use cases so we’re often challenged to ensure that our systems are compatible with as many platforms as possible. We achieved this by pursuing a self-contained architecture for our sensors, which include their own navigation system, data storage system, data triggering system, and several other features that allow them to operate completely independently from the drones that carry them.

In terms of integration, we’ve developed simple and robust mounting kits for many of the most popular drones and our partnership with DJI resulted in a tightly integrated solution for their DJI Matrice 200 Series of drones.

We have also pursued several custom integrations with the flight planning apps used to autonomously fly the drones used with our sensors. This includes configuration of the flight planner based on our sensor parameters as well as the automatic detection, configuration, and real-time feedback included with the 3PX sensor.

  1. Collecting quality remote sensing data isn’t an easy task. How do you ensure that farmers who are flying their drones equipped with SlantRange sensors aren’t doing something wrong? How do you let them know that something isn’t correct before they spend a few hours collecting the data only to find out the data isn’t useful?

As a starting point, we provide a full onboarding process to each of our customers to ensure they are familiar with the hardware setup as well as the data collection and data processing workflows. We also offer a more in-depth training course for those who prefer more personalized instruction, which also includes a detailed introduction to our suite of analytics.

We’ve always provided some quick-look tools in our software that allow our customers to evaluate the area coverage of a flight and to check for any gaps immediately after a data collection. We’re also implementing some new features that analyze the image content for quality metrics such as exposure and focus. However, these are all tools that are used after a flight has been completed.

Our 3PX sensor provides real-time feedback to the user to ensure they’re collecting high quality data. These real-time metrics include the status of the sensor’s navigation system, the status of the data storage system and, most importantly, measurements from the AIS. If lighting conditions drop too low for quality data, the user will be notified immediately, allowing them to make the decision to abort the mission if they choose. All of this information is transmitted using DJI’s Payload SDK and is displayed in real-time on the same mobile device used to operate the drone.

  1. You also recently announced an additional service that is frankly quite interesting – “Aerial Phenotyping”. What is that all about? Could you tell us more!

Over the past several years, we’ve seen increasing interest in using our sensors and analytics for very specific applications within the agriculture research community. Much of the in-field research is conducted using test plots, which are arrays of small plots, typically a few rows of plants wide and only several meters long, that are laid out in a grid pattern across a test site. Each of the plots may contain a different seed hybrid, treatment program, or both, with the intent to evaluate the performance of the crop across a season.

Phenotyping involves the measurement of the various metrics about the crop to support the goals of the trial. This has traditionally been a manual process and can be very time-consuming, expensive, and prone to error. We saw an opportunity to customize our data collection and processing workflows to provide this data from an aerial platform in an automated and repeatable way. This included some enhancements to our navigations system, including the integration of RTK GPS, as well as some customization of our analytics to accurately assign the contributions of each image to the appropriate plots within the trial.

This led to the launch of our Aerial Phenotyping services. The service includes the collection of the imagery over the trial, typically multiple times over the course of a season, and the tabulated results are delivered to the customer for each and every plot within the trial, including metrics such as plant counts, plant size distributions, chlorophyll index, vegetation fraction, NDVI, stress values, yield potential, and other custom analytics based on the needs of the customer. This provides a turnkey solution for our customers who can focus on the results and their research rather than the process of collecting and processing the data itself. We are now going into our 3rd season of the service and are proud to support the research of companies such as Bayer, BASF, Land O’Lakes, Syngenta, and AgReliant.

  1. As a key player in a successful startup, I am sure that there are many things that you must have learnt along the way. What was the most interesting feedback that you received so far?

One of our advisors once told us to do things that don’t scale in order to learn how to scale. While it seems a bit counter-intuitive, it actually makes a lot of sense. His point was that you sometimes have to be hyper-focused on a particular customer segment, or even a specific customer, to learn what it takes to delight your broader customer base. This may involve some completely unscalable approaches or methods but from that process you can begin to establish more scalable ways to achieve the same outcome.

As an example, we learned early on that the range of data needs and use cases across all of our customers is immense. We often had customers asking us to develop customized algorithms to detect the particular crop conditions they cared about. One of our customers in Southern California wanted us to develop an algorithm to detect dodder, a parasitic weed that was causing significant damage in their alfalfa fields. Through the process of developing the algorithm, which was very specific to that weed and not scalable to other crops, we developed and launched our Smart DetectionTM tool. This feature allows a user to draw a region of interest around an anomaly on one of their maps and the software uses the spectral signature from that region to find occurrences of the same feature across the entire field. Our customers have successfully used this tool to identify weeds, irrigation leaks, and lodged plants, and the applications continue to expand every day.

  1. More often than not it takes a while to find a business model that works for you and your clients. Have you cracked that code already?

While our business model may evolve as we continue to grow, our current model is serving us quite well. Our business is currently divided into two parts. First, we sell our sensors and subscriptions to our SlantViewTM software to growers, agronomists, drone service providers, and drone system integrators. Second, we provide data analytics services on a contract basis, which includes our Aerial Phenotyping service. The analytics we develop through our data services will typically flow into our commercial SlantViewTM software to expand and enhance the capabilities of that business unit.

  1. You are based in San Diego, how’s the startup scene? Are there many investors specifically looking at Ag-tech companies? Are there any local meetups/events that cater to the geo community?

The startup scene in San Diego is definitely thriving and continues to expand. It’s establishing itself as a desirable alternative to Silicon Valley for both investors, new companies, and talent. It’s definitely expanding beyond its history of biotech and defense with many new startups in both Agtech as well as B2B SaaS services.

San Diego is also well-known for its expertise in remote sensing, robotics, and unmanned systems, partially due to the concentration of defense technology companies and earth sciences research. While I don’t know of any specific geo events, there are certainly events focused on robotics and unmanned systems, which include the automation and navigation aspects of those systems.

  1. Okay, this is a tricky one – on a scale of 1 to 10 (10 being the highest), how geoawesome do you feel today?

We’re developing a new RTK navigation system to support our more advanced analytics and we’re seeing great results so I’ll say I’m feeling a solid 9 on the geoawesome scale; I’ll give it a 10 when it launches!

  1. Any closing remarks for anyone looking to start their own geo startup?
    If anyone would like to reach you, what would be the best way to do so?

One piece of advice I can offer, which has been shared many times before, if you’re not completely embarrassed by your first product launch, you waited too long!
