Space is a lot closer than it used to be. Companies like Planet and Spire are sending more satellites into orbit than ever before, providing an unprecedented near-real-time view of of every corner of the earth, from wheat fields in Egypt to glaciers in Antarctica. Here are five ways that companies are using this constant stream of data and images to bring more transparency and efficiency to different industries here on the ground.

Agriculture

A number of companies use satellite imagery to predict annual farm yields—mostly focusing on major crops like wheat, corn and soy—and produce estimations that are useful for farmers and commodities traders alike. But Vinsight, a small startup in California, has decided to instead focus on grapes and almonds, two of the state’s most valuable agricultural products. “Even the U.S. Department of Agriculture doesn’t forecast those crops,” says founder Megan Nunes. “We thought it made sense to apply the technology to a sector that really needs it.” Grape and almond farmers typically see a 30-40% error rate when they predict their seasonal outputs, Nunes says. With Vinsight’s technology, which uses machine learning to analyze satellite images, taking into account external factors like location, weather, and historical performance, farmers can get a yield prediction that is three or four times more accurate. That information, says Nunes, can help them save on labor costs, estimate their revenue for the year, and strike better deals with buyers.

Another analytics company, FarmShots, digs even deeper. The North Carolina–based startup analyzes specific fields and patches of farmland, studying factors like light absorption and land elevation to detect the presence of pests or diseases on individual fields. FarmShots alerts its clients when there’s a problem, and is currently building out its recognition algorithms to easily identify the cause, such as fungus or trapped rainwater. Through a recent partnership with John Deere, the company’s technology has been built into tractors and other equipment, so those findings can automatically direct machines on the ground. “You don’t want to put on an even coat of fertilizer,” says FarmShots CEO Joshua Miller. “We generate a map to instruct the machine to put less fertilizer on the areas that are healthy and more on the areas that are unhealthy.”

Shipping

Before the era of CubeSats, government-owned satellites tended to cover only the more populated areas of earth—leaving remote corners of the ocean in the dark. Shipping routes in the Arctic, for example, weren’t covered by satellites or signal towers, which led to a dearth of knowledge about who was passing through and what they were doing. In March, Spire partnered with the National Geospatial-Intelligence Agency (NGA) and Ball Aerospace to monitor these blind spots. “The suspicion is that there’s more traffic there than we realize,” says Nick Allain, head of Creative and Brand at Spire. “Whose water are they actually traversing? Where is an oil spill most likely to happen? Are ships meeting in the middle and sharing things they’re not supposed to be sharing?” The partnership will look to gather that information and come up with solutions that prevent black-market trading and make Arctic sea routes safer for shippers.

Farther south, Spire has used its capabilities to prevent similar dangers in the Indian Ocean. It works with the Indonesian government to cut down on illegal fishing activity by flagging ships that are in restricted waters, and is currently testing a new capability that can detect what kind of fish a boat is trawling for based on its patterns at sea. “By looking at the pattern, you can say, ‘Wait, they’re not supposed to be fishing for crab, they’re supposed to be fishing for tuna,'” says Allain. “It was hard to track that before.” Spire also provides its data to piracy forecasting companies, helping them keep an eye on risky spots in the ocean.

Emergency Response

When disaster hits—whether it be a tsunami or a mortar attack—satellite images can be a crucial tool for governments and aid organizations trying to assess the damage and direct relief efforts. Planet, which has launched nearly 150 satellites into orbit, uses its images to create maps that show an affected area before and after a disaster, helping field workers quickly identify roads that have been blocked or important buildings, such as schools or hospitals, that have been damaged. “It can really increase the efficiency and the effectiveness of response efforts,” says Tara O’Shea, a program manager for impact initiatives at Planet. “Rather than having to send folks out into the field to survey, which can be costly and time intensive, we can fulfill that need with our imagery.” After a hurricane hit Haiti last fall, the company jumped into action and produced before-and-after maps of the country within days.

Around that time, Planet decided to form a disaster response team focused on these efforts. Many aid organizations or community groups don’t have staff members with image processing and geospatial analysis capabilities, which are critical for turning the satellite images into useful information. “People on the ground just need a simple PDF that they can laminate and carry outside,” says O’Shea. To get those assets to first responders faster, Planet worked with the Digital Humanitarian Network to enlist about 20 volunteers from around the world; after receiving training from Planet on how to use its platform and work with its imagery, those volunteers were put on call, ready to respond to a disaster at any time of day.
