EOSDA Crop Monitoring
EOSDA Crop Monitoring is the flagship precision agriculture platform from EOS Data Analytics, a global Earth observation and geospatial analytics company. The platform provides satellite-based crop monitoring, NDVI field analytics, weather integration, field scouting tools, and yield prediction capabilities delivered through a REST API and a web application interface. EOSDA Crop Monitoring is designed for agritech developers, precision farming service providers, and agricultural enterprises that need to monitor crop health across portfolios of farm fields using satellite imagery as the primary data source.
The platform's automated field monitoring model registers farm fields as GeoJSON polygons and automatically processes available satellite imagery over those fields as new passes occur. Users do not need to request individual images or manage satellite tasking — once fields are registered, EOSDA's system continuously processes incoming imagery and makes vegetation index time series available through the API. This automation is particularly valuable for agritech companies managing large numbers of farmer fields across Nigeria, as manual image processing at scale would be impractical without automated pipelines.
NDVI (Normalized Difference Vegetation Index) time series for each registered field form the core monitoring product. NDVI tracks green vegetation density and is highly correlated with biomass, canopy cover, and overall crop health. For Nigerian crops — cassava, maize, sorghum, millet, rice, and vegetables — NDVI trajectories through the growing season follow predictable patterns shaped by planting date, vegetative growth, canopy closure, and eventual senescence. Deviations from expected seasonal NDVI patterns are the primary signal of crop stress, disease pressure, or management-related problems.
Multiple vegetation indices are available beyond NDVI: EVI (Enhanced Vegetation Index) for better performance in dense canopy conditions, NDWI (Normalized Difference Water Index) for water content and stress monitoring, MSAVI (Modified Soil-Adjusted Vegetation Index) for early season when crop cover is sparse, and SAVI for fields with variable soil exposure. Nigerian agritech platforms can select the most appropriate index for each crop type and growth stage rather than applying NDVI universally across all monitoring scenarios.
Weather data integration through EOSDA connects satellite crop observations with meteorological context from MERRA-2 reanalysis data and forecast models. Historical temperature, precipitation, wind speed, and solar radiation data are available for each field location, enabling correlation of NDVI anomalies with weather events. For Nigerian farms where the timing and intensity of seasonal rains determines much of crop health variability, having weather context alongside satellite vegetation data in a single API is significantly more useful than querying two separate systems.
Satellite imagery selection in EOSDA covers multiple sensors with different resolution and revisit trade-offs. Sentinel-2 provides 10-meter resolution imagery with approximately 5-day revisit time. Landsat-8 and Landsat-9 provide 30-meter resolution with 16-day revisit. PlanetScope commercial imagery provides 3-meter resolution with daily revisit for applications requiring the finest spatial detail and most frequent updates. Nigerian precision agriculture applications can use the appropriate sensor tier for their specific needs and budget constraints.
Field scouting integration within EOSDA Crop Monitoring links satellite observations to ground-truth scouting workflows. When satellite data identifies anomalies — areas of low NDVI within an otherwise healthy field — the platform can generate scouting tasks directing field agents to specific GPS-referenced locations within the field to investigate the anomaly and record their findings. This closed loop between remote sensing and ground verification improves the efficiency of field scouting operations for Nigerian agricultural extension services and farm management companies managing distributed farm portfolios.
Zonal statistics for registered fields provide summary metrics that make field health data accessible to users without image interpretation skills. Mean NDVI across the field, percentage of field area below health threshold, and comparison to previous observation periods give farm managers and farmers themselves actionable health summaries that inform decisions without requiring them to interpret satellite imagery directly.
