A team of researchers led by Professor Jin Wu, at the University of Hong Kong, has been studying tropical and temperate forest phenology—the rhythms and periods of life. Aided by the high revisit rate of Dove satellites, Jing Wang and…...
Tracking the scientific discoveries made by Planet's Education and Research community
Early in the COVID-19 pandemic, humanity noted several effects of lockdowns on the Earth system from orbit, including vacant highways, and reductions in air pollution. People affected in Venice reported that the local waters were clearer than they had been…
CONTINUE READINGUnique 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…
CONTINUE READINGAs Planet's Education and Research Community continues to grow, students are increasingly working with Planet imagery in college courses. At Stanford University, several students recently utilized Planet imagery in Computer Science 230: Deep Learning. Ian Avery Bick, Dennis Wang and…
CONTINUE READINGImproving crop yields, vigor and health, can be facilitated by better monitoring of the cross-sectional area of vegetation—i.e., Leaf Area Index or LAI. However, measuring LAI on the ground is time consuming and expensive. Sentinel-2, operated by the European Space Agency, publishes a global LAI product; but at 10m resolution and a […]
CONTINUE READINGGlacial lakes in mountainous regions are prone to outburst floods that can devastate entire communities. With climate change, glacial ice is thinning and retreating in the Hindu Kush, Karakoram and Himalaya region, posing an increasing threat to human life and requiring improved monitoring. Nida Qayyum, in the Department of Space Science at […]
CONTINUE READINGOn a rapidly changing Earth, space-based imaging provides one of the most critical inputs to our scientific understanding of the whole Earth system. With the rapid increase in the number of medium- to high-resolution imaging sensors, there is increasing need for standard calibration methodology. An increase in sensor fusion, in which researchers […]
CONTINUE READINGChange in vegetation color, chemistry and metabolic activity is one of the most striking signals of life in our biosphere. Satellite imagery plays an important role in effectively retrieving and mapping these vegetation changes over time—also called phenology. The rapid revisit period of the PlanetScope cubesat constellation provides researchers with a unique […]
CONTINUE READINGCoastal wetlands, especially salt marshes, store vast amounts of terrestrial carbon both above and belowground. Conserving and restoring them can help sequester such carbon, but sea-level rise and other anthropogenic threats risk liberating these long-term carbon stores to the atmosphere where they would contribute to climate change. Gwen Miller, a Ph.D. Student […]
