Commercial and Government Researchers Move Toward Collaborative Satellite Calibration

Paper

On 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 […]

PlanetScope Time-series Used to Understand Vegetation Phenology

Paper

Change 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 […]

Dove Imagery Used to Map Biomass in Coastal Wetlands

Paper

Coastal 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 […]

Dove Imagery Used for Bathymetric Mapping

Paper

Satellite-derived bathymetry has numerous applications, including enhanced mapping and classification of bathymetric features such as coral reefs and seagrass meadows, as well as use in maritime navigation and coastline infrastructure. Dimitris Poursanidis from the Foundation for Research and Technology in Hellas, with colleagues from the German Aerospace Centre, used Planet’s Dove images […]

Mapping Landslide Susceptibility in Dove Imagery after the 2018 Tomakomai Earthquake

Paper

Globally, landslides kill ~5,000 people per year. If landslides—including rock falls, mudslides and other surface failures—can be better predicted, these deaths could be avoided. Landslides are highly heterogeneous, both spatially and temporally. They are more common in the steep, mountainous regions of the Earth, but also more frequent during particular seasons due […]

Semi-arid Rangeland Phenology Revealed with the Planet Dove Constellation

Paper

Temporal resolution is one of four axes by which one may judge the value of a remote sensing data source. Unlike spatial, spectral and radiometric resolution, temporal resolution can be used to decompose the day-to-day dynamics of ecosystems, revealing their phenology—the natural processes by which ecosystems (particularly vegetation) change over time. A […]

River Morphology Dynamics Revealed with Dove Imagery

Paper

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

Paper

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 […]
