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 […]

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 […]

Insights into Vegetation Dynamics and Terrestrial Evaporation

Paper

Planet’s constellation of satellites, with daily revisit rates and sub 5 m resolution, provides the ability to overcome the usual spatiotemporal restrictions associated with traditional remote sensing. Matt McCabe and team explore the suitability of Planet imagery for an array of retrieval opportunities pertinent to hydrology, including leaf area index (LAI) and […]

Mapping Winter Cropped Area of Smallholder Farms

Paper

Fine-scale agricultural statistics are important tools for understanding trends in food production, especially in smallholder systems where heterogeneity in production is common. Satellite data is a key component to collecting these statistics for smallholder systems, though not without challenges such as complex sub-pixel heterogeneity, little to no available calibration data, and high […]

Crop Yield Variations in Smallholder African Systems

Paper

Improving the productivity of smallholder farms is thought to be a key component of the effort to reduce global poverty and increase food security, yet the productivity of smallholder farms remains poorly measured around the world. Using SkySat imagery validated against two years of field data, new research shows that satellite imagery […]
