In 2016, two glaciers in Tibet sheered down to their bed, erupting into avalanches. The first disaster killed nine people. A major study, published in Nature Geosciences, examined Planet imagery in the months leading up to the avalanches, and their aftermath. The work was subsequently featured in the The New York Times: “‘…it […]

Using the Yukon Flats in Alaska as the test study area, Sarah Cooley and colleagues evaluated the potential scientific utility of the Planet Dove constellation for hydrologic modeling and research. The study concluded that Planet imagery can improve mapping and tracking changing inundation extent of hundreds of small, heterogeneous water bodies in […]

Jakob Steiner and team use digital elevation models and Landsat imagery in combination with high resolution Planet data to quantify surface elevation changes and flow velocities during a glacial surge of the Khurdopin Glacier. They conclude that the high frequency of Planet imagery is useful to capture peak surge velocities that are […]

Planet’s constellation of satellites, with daily revisit rates and sub 5 m resolution, provides the ability to overcome the usual spatiotemporal restrictions associated with traditional remote sensing. Matt McCabe and team explore the suitability of Planet imagery for an array of retrieval opportunities pertinent to hydrology, including leaf area index (LAI) and […]

Unique among commercial sensors, the SkySats are capable of full-motion, panchromatic video from space. Ramon Arrowsmith, professor of Geology at Arizona State University decomposed one SkySat video to produce 3D models. As Ramon notes in his Active Tectonics Blog, SkySat captured video over a large open pit mine in Uşak, Turkey. Parallax—the […]
