Science and Technology of Planet Satellite Crop Imaging

The Planet Satellite Constellation

At the heart of Planet Satellite Crop Imaging is the company's unique and proprietary satellite constellation, which consists of over 150 small, low-cost, and high-performance satellites that orbit the Earth at an altitude of around 400 kilometers. These satellites, known as Doves, are designed and built in-house by Planet, using commercial off-the-shelf components and agile aerospace engineering techniques that enable rapid iteration, deployment, and scaling of the technology.

The Dove satellites are equipped with high-resolution, multispectral imaging sensors that can capture imagery of the Earth's surface at a spatial resolution of up to 3 meters per pixel, across a range of spectral bands that are optimized for agricultural applications. These spectral bands include:

Blue (455-515 nm): This band is sensitive to atmospheric scattering and can be used to estimate the amount of haze or smoke in the atmosphere, which can affect the quality and accuracy of the imagery.
Green (500-590 nm): This band is sensitive to the amount of chlorophyll in vegetation, and can be used to estimate the health and vigor of crops, as well as to detect early signs of stress or disease.
Red (590-670 nm): This band is also sensitive to chlorophyll, but is more strongly absorbed by vegetation than the green band, making it useful for distinguishing between different types of crops and for estimating crop biomass and yield.
Red Edge (690-740 nm): This band is located at the transition between the red and near-infrared regions of the spectrum, and is particularly sensitive to changes in plant chlorophyll content and leaf structure, making it useful for detecting early signs of stress or disease, and for estimating crop nitrogen status.
Near-Infrared (780-860 nm): This band is strongly reflected by healthy vegetation, due to the internal structure of plant leaves, and can be used to estimate crop biomass, leaf area index, and water content, as well as to distinguish between different types of crops and land cover.

By capturing imagery across these multiple spectral bands, the Dove satellites can provide a rich and detailed view of crop conditions and variability, at a frequency and scale that is unmatched by traditional satellite or aerial imaging systems. The Dove satellites orbit the Earth in a sun-synchronous pattern, passing over the same location at the same local solar time each day, which enables consistent and comparable imaging of crop growth and development over time.

Image Processing and Analysis

Once the Dove satellites have captured the raw imagery of the Earth's surface, the data is transmitted to the Planet's ground stations, where it undergoes a series of processing and analysis steps to generate useful and actionable insights for agricultural applications. These steps include:

Radiometric Calibration: This step involves converting the raw digital numbers captured by the satellite sensors into physically meaningful units of spectral reflectance, which represent the amount of light reflected by the Earth's surface at different wavelengths. This calibration is critical for ensuring the accuracy and consistency of the imagery across different satellites, sensors, and periods, and for enabling quantitative analysis of crop conditions and variability.
Atmospheric Correction: This step involves removing the effects of atmospheric scattering and absorption on satellite imagery, which can distort the spectral signatures of crops and other land cover types. This correction is typically performed using physical models of atmospheric radiative transfer, which estimate the amount of atmospheric interference based on factors such as the satellite viewing angle, the solar zenith angle, and the atmospheric conditions at the time of image acquisition.
Geometric Correction: This step involves correcting the satellite imagery for geometric distortions caused by factors such as the curvature of the Earth, the motion of the satellite, and the topography of the land surface. This correction is typically performed using ground control points and digital elevation models, which enable accurate georeferencing and orthorectification of the imagery, and ensure that the imagery is properly aligned with other spatial data layers, such as field boundaries and soil maps.
Spectral Indices: This step involves calculating various spectral indices from the calibrated and corrected satellite imagery, which are mathematical combinations of different spectral bands that are sensitive to specific crop characteristics or conditions. Some of the most commonly used spectral indices for agricultural applications include:

Normalized Difference Vegetation Index (NDVI): This index is calculated as the difference between the near-infrared and red bands, divided by their sum, and is a widely used indicator of vegetation health, vigor, and biomass. NDVI values range from -1 to 1, with higher values indicating more healthy and dense vegetation, and lower values indicating stressed or sparse vegetation.
Normalized Difference Red Edge (NDRE): This index is similar to NDVI, but uses the red edge band instead of the red band, and is more sensitive to changes in chlorophyll content and leaf structure, making it useful for detecting early signs of stress or disease, and for estimating crop nitrogen status.
Normalized Difference Water Index (NDWI): This index is calculated as the difference between the green and near-infrared bands, divided by their sum, and is sensitive to changes in vegetation water content, making it useful for estimating crop water stress and irrigation requirements.
Soil-Adjusted Vegetation Index (SAVI): This index is a modification of NDVI that includes a soil adjustment factor, which accounts for the effects of soil brightness on vegetation indices, and is particularly useful for monitoring crops in areas with high soil variability or low vegetation cover.

Machine Learning and Data Fusion: This step involves using advanced machine learning algorithms and data fusion techniques to extract meaningful and actionable insights from the spectral indices and other spatial data layers, such as weather data, soil maps, and crop management records. These algorithms can be trained to recognize patterns and relationships in the data that are indicative of specific crop conditions or outcomes, such as yield potential, nutrient deficiencies, or pest and disease outbreaks. By combining multiple data sources and leveraging the power of machine learning, Planet Satellite Crop Imaging can provide more accurate, detailed, and timely insights into crop performance and variability than traditional remote sensing approaches.

These integrations enable end-users to leverage the power of Planet Satellite Crop Imaging in combination with other data sources and decision support tools, such as soil maps, yield monitors, and variable rate application systems, to optimize crop management and performance at the field and sub-field level.

Applications and Benefits of Planet Satellite Crop Imaging

Crop Health Monitoring and Management

One of the key applications of Planet Satellite Crop Imaging is the monitoring and management of crop health and performance throughout the growing season. By providing frequent and high-resolution imagery of crop conditions and variability, Planet Satellite Crop Imaging enables farmers and agronomists to:

Detect and Diagnose Crop Stress: The spectral indices and machine learning algorithms used in Planet Satellite Crop Imaging can detect early signs of crop stress, such as nutrient deficiencies, water stress, or pest and disease outbreaks, before they become visible to the naked eye or cause significant yield losses. By identifying and diagnosing crop stress promptly, farmers can take corrective actions, such as applying fertilizers, irrigation, or pesticides, to mitigate the impacts of stress and optimize crop health and productivity.
Monitor Crop Growth and Development: Planet Satellite Crop Imaging can also monitor crop growth and development over time, by tracking changes in vegetation indices and other spectral features that are indicative of crop biomass, leaf area, and phenology. This information can be used to assess crop progress and maturity and to identify areas of the field that are performing above or below average, which can inform management decisions, such as harvest timing, input application, or crop rotation planning.
Optimize Nutrient Management: Planet Satellite Crop Imaging can also be used to optimize nutrient management, by estimating crop nutrient status and requirements based on spectral indices, such as NDRE, which are sensitive to leaf chlorophyll content and nitrogen concentration. By combining this information with soil test results, crop yield goals, and nutrient uptake models, farmers can develop site-specific and dynamic nutrient management plans that match nutrient supply with crop demand, and minimize the risks of nutrient deficiencies, excesses, or losses.
Guide Precision Irrigation: Planet Satellite Crop Imaging can also guide precision irrigation, by estimating crop water stress and evapotranspiration based on spectral indices, such as NDWI, which are sensitive to leaf water content and temperature. By combining this information with weather data, soil moisture sensors, and irrigation system performance data, farmers can develop site-specific and dynamic irrigation schedules that optimize water use efficiency, reduce water stress, and improve crop yield and quality.

Crop Yield Forecasting and Estimation

Another key application of Planet Satellite Crop Imaging is the forecasting and estimation of crop yields, which can provide valuable information for farmers, crop insurers, commodity traders, and other stakeholders in the agriculture value chain. By leveraging the high spatial and temporal resolution of Planet's satellite imagery, along with advanced machine learning algorithms and crop growth models, Planet Satellite Crop Imaging can:

Predict Crop Yields: Planet Satellite Crop Imaging can predict crop yields at the field and regional level, by estimating crop biomass, leaf area index, and other biophysical parameters that are strongly correlated with yield potential. These predictions can be made throughout the growing season, based on the real-time monitoring of crop growth and development, and can be updated as new information becomes available, such as weather events, management practices, or market conditions. By providing early and accurate yield forecasts, Planet Satellite Crop Imaging can help farmers optimize their crop management and marketing strategies and can help crop insurers and commodity traders manage their risks and investments.
Assess Crop Damage and Losses: Planet Satellite Crop Imaging can also assess crop damage and losses due to various stressors, such as drought, flooding, hail, or pest and disease outbreaks. By comparing the spectral signatures and vegetation indices of affected areas to those of healthy or historical reference areas, Planet Satellite Crop Imaging can quantify the extent and severity of crop damage and can estimate the potential yield losses and economic impacts. This information can be used by farmers to file crop insurance claims, by crop insurers to verify and process claims, and by government agencies to provide disaster assistance and support to affected regions.
Monitor Crop Quality and Composition: Planet Satellite Crop Imaging can also monitor crop quality and composition, by estimating various biochemical and physiological parameters that are related to crop nutritional value, processing quality, or marketability. For example, Planet Satellite Crop Imaging can estimate crop protein content, oil content, or sugar content, based on spectral indices that are sensitive to these parameters, such as the Nitrogen Reflectance Index (NRI) or the Anthocyanin Reflectance Index (ARI). This information can be used by farmers to optimize their crop management practices, such as fertilization or harvest timing, to meet specific quality or composition targets, and can be used by food processors and retailers to source and differentiate their products based on quality attributes.

Sustainable Land and Water Management

A third key application of Planet Satellite Crop Imaging is the support of sustainable land and water management practices, which can help to conserve natural resources, reduce environmental impacts, and enhance the resilience and productivity of agricultural systems. By providing detailed and timely information on land use, land cover, and water resources, Planet Satellite Crop Imaging can:

Map and Monitor Land Use and Land Cover: Planet Satellite Crop Imaging can map and monitor land use and land cover at high spatial and temporal resolutions, which can provide valuable information for land use planning, policy-making, and resource management. For example, Planet Satellite Crop Imaging can identify and track changes in crop types, cropping patterns, and crop rotations, which can inform decisions on agricultural zoning, conservation programs, or infrastructure investments. It can also detect and monitor land use changes, such as deforestation, urbanization, or land degradation, which can have significant impacts on biodiversity, ecosystem services, and climate change.
Assess and Manage Water Resources: Planet Satellite Crop Imaging can assess and manage water resources, by estimating and monitoring various hydrological parameters, such as evapotranspiration, soil moisture, and surface water extent and quality. This information can be used to develop and implement sustainable water management practices, such as precision irrigation, drought monitoring, or water quality protection. For example, Planet Satellite Crop Imaging can estimate crop water requirements and irrigation schedules based on real-time monitoring of crop growth and weather conditions, which can help optimize water use efficiency and reduce water stress. It can also detect and monitor water quality issues, such as algal blooms, sediment loading, or nutrient pollution, which can inform targeted interventions and policy responses.
Support Ecosystem Services and Biodiversity: Planet Satellite Crop Imaging can support ecosystem services and biodiversity, by providing information on the extent, condition, and connectivity of natural habitats and biodiversity hotspots, such as wetlands, forests, grasslands, or riparian corridors. This information can be used to identify and prioritize areas for conservation, restoration, or sustainable land management, and to monitor the effectiveness of conservation programs and policies. For example, Planet Satellite Crop Imaging can map and monitor the extent and quality of pollinator habitats, such as wildflower strips or hedgerows, which can provide valuable ecosystem services for crop pollination and biodiversity conservation. It can also detect and monitor the impacts of agricultural practices, such as pesticide use or tillage, on soil health, carbon sequestration, and water quality, which can inform the adoption of more sustainable and regenerative farming practices.
