Tropical and Temperate Forest Phenology Revealed by Planet Imagery

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…...

PlanetScope Imagery Reveals that COVID Lockdown Reduced Sediments in Waters of Venice

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…

Structure-from-motion with SkySat Video

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…

River Morphology Dynamics Revealed with Dove Imagery

The movement of river sediment influences many aspects of land management, including water quality and the life cycle of dams and other impoundments. Hydrologists will benefit from improved methodologies to track river sediment flow and geomorphological evolution of the river channel. Robert Strick, from the University of Brighton, and colleagues used a […]

Sub-daily Dove Imagery Used to Measure River Velocity

If it were possible, a stationary observer in sun synchronous orbit would see one Planet Dove satellite rocket past every ~90 seconds. At polar latitudes, the relative speed of Earth’s rotation is much lower, like the inside tracks of a vinyl record. As a result, Planet often collects multiple images of the […]

RapidEye Imagery Used to Monitor Suspended Sediments in Tropical Rivers

The flow of suspended sediment—fine particles carried by the water column—varies widely in tropical rivers, and can influence water availability, silting of reservoirs and pollution. Monitoring sediment loads over large rivers can be difficult with ground stations, making remote sensing a preferred solution. However, high spatial and temporal resolution are required to […]

Dove and RapidEye Images Reveal the Climate Dynamics of Tens of Thousands of High-latitude Lakes

In the Arctic and Boreal regions, millions of freshwater lakes influence carbon dioxide and methane emissions to the atmosphere. Lakes that are more dynamic, with a variable shoreline, may have a greater flux of these greenhouse gases. Leveraging the Planet Dove and RapidEye constellations, which collectively image daily and sometimes multiple times […]

Convolutional Neural Networks used to Detect and Classify Ships in Dove Imagery

With daily imagery over ports and coastlines, one of the most useful potential applications of Planet’s Dove imagery is the detection and classification of maritime vessels. Ship tracking has a vital role in security, but the enormous number of ships at sea at any given time limits the effectiveness of classical, human-powered […]
