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 […]

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 […]

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 […]

When disaster strikes, accurate information about the scale and scope of impact becomes critical. The first 24 hours are often the most important, and any accurate data may prove life saving. Leveraging data from Planet’s Disaster Program, Bruno Adriano and his team used a variety of data sources and machine learning to […]

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 […]
