Dove Imagery used to Assess Economic Damage after a Wildfire in Haifa, Israel

Paper

In November, 2016, Haifa, Israel experienced a fire on the Wildland-Urban Interface (WUI), causing damage to homes and other infrastructure in the urban forest landscape. The damage was visible in several Earth Observation datasets, including MODIS, Sentinel-2, and the Planet Dove constellation. Yaron Michael, in the Department of Geography and Environment at […]

Change Detection in 3D: Generating Digital Elevation Models from Dove Imagery

Paper

Many communities live in mountainous or glaciated terrain, with a constant threat of landslides and avalanches. Remote sensing methods, including construction of digital elevation models (DEMs), have the potential to detect deformation of the Earth’s surface—not only horizontally, but also vertically. While active sensors like radar are excellent for detecting this 3D […]

Daily, High-resolution Leaf Area Index from Sensor Fusion with Planet, Landsat and MODIS

Paper

Classic remote sensing for agricultural relies heavily on indices like NDVI (Normalized Differential Vegetation Index), which uses information from the red and near-infrared portions of the spectrum to provide an indicator of vegetation greenness and vitality. However, other indices, often implicating other parts of the spectrum, may provided added and actionable information […]

Charting Karst Topography in the Black Hills Region of South Dakota and Wyoming

Paper

Straddling the South Dakota-Wyoming border, the Black Hills region is characterized by karst features—caves, sinkholes and other landforms created as water erodes dolomite and limestone deposits. Given the importance of water in creating karst formations, climate change has the potential to alter karst intensity. Barbara Theilen-Willige, Professor at Technical University Berlin, used […]

SkySat-3 Demonstrates Asteroid Imaging

Paper

The proliferation of small satellites may make it easier to track near-Earth objects—asteroids and other potentially hazardous objects that could impact our Planet. In collaboration with Planet, Chengxing Zhai and team utilized SkySat-3 to demonstrate imaging of the main belt asteroid, 889 Erynia, and near-Earth oject 1998YP11. From January through April of 2017, SkySat-3 […]

Shoreline Changes in RapidEye Time Series of Pecém Port, Ceará, Brazil

Paper

Shoreline geomorphology is the result of natural forces including tidal action and storm activity, as well as anthropogenic changes to coastal infrastructure that can alter shoreline evolution and stability. High temporal- and spatial-resolution imagery can increase our understanding of the mechanisms that lead to these changes, and determine the influence of human […]

Sensor Fusion of Planet, Landsat and MODIS Data for Unprecedented Land Surface Monitoring

Paper

In the midst of a revolution Earth Observation, due to increasingly diverse and temporally dense data feeds enabled by cubesats and other sensors, there is a need to be interoperable across sensors. In the journal Remote Sensing of Environment, Rasmus Houborg and Matt McCabe present the Cubesat-enabled Spatio-Temporal Enhancement Method (CESTEM), which […]

Change Detection of Mediterranean Seagrasses Using RapidEye Time Series

Paper

Seagrass beds are one of the most important ecosystems in the Mediterranean region, supporting an enormous diversity of marine fauna. However, with anthropogenic influences including dredging and modification of shorelines, pollution and other drivers, seagrass ecosystems facing increasing threats. To improve monitoring of seagrass extent, Dimosthenis Tranganos and Peter Reinartz from the […]

Tracking Dynamic Changes in Northern Surface Waters

Paper

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 […]

Extreme Flow Velocities and Formation of a Dammed Lake

Paper

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 […]
