Drones, satellite agro-analytics, field digital twins

Drones, satellite agro-analytics and field digital twins form the observation-and-simulation layer of precision agriculture — the cameras in the sky and the models they feed. DJI Agriculture’s Agras T100, T70P and T25P spray and spread drones (built on over 12 years of R&D) carry crop inputs to the plant; Planet Labs’ Crop Biomass fuses Sentinel-1 radar with Sentinel-2 and PlanetScope optical imagery into a daily, cloud-free biomass raster at 3 m and 10 m resolution; and field digital-twin platforms (Climate FieldView, xarvio FIELD MANAGER, Pix4Dfields) turn that imagery into NDVI maps, growth-stage models and zone prescriptions. This category hands its prescriptions off to the variable-rate actuation layer covered by the sibling precision-agriculture-agritech article.

The key directions of aerial and space agro-analytics are:

1. Agricultural drone platforms (Agricultural Drone Platforms): spray, spread and scouting drones (DJI Agras T100/T70P/T25P) carrying heavier payloads for crop-input application and aerial capture.
2. Satellite earth-observation analytics (Satellite Earth-Observation Analytics): daily, cloud-free biomass and vigor rasters fused from radar and optical constellations (Planet Crop Biomass at 3 m/10 m).
3. Field digital-twin platforms (Field Digital-Twin Platforms): whole-season field models (Climate FieldView, xarvio FIELD MANAGER) combining satellite, weather and field-history data into prescriptions.
4. Drone-borne multispectral sensing (Multispectral Drone Sensing): synchronized thermal and multispectral capture (Sentera 6X: FLIR Boson+ plus six bands) for NDVI, NDRE and biomass at 3 cm GSD.

Cross-cutting technologies of the sector:

• Optical–radar data fusion (Optical–Radar Data Fusion): combining Sentinel-1 SAR with Sentinel-2/PlanetScope optical imagery for daily, cloud-free biomass and vigor rasters.
• Drone multispectral and thermal sensing (Drone Multispectral & Thermal Sensing): six-band multispectral plus radiometric thermal capture in a single pass for co-registered NDVI and stress maps.
• Digital-twin crop modeling (Digital-Twin Crop Modeling): growth-stage and biomass models that update daily from satellite and weather data to drive in-season prescriptions.

The stack pairs aerial/space capture with analytics and digital-twin modeling.

1. Agricultural drone platforms and sensing (Agricultural Drone Platforms & Sensing):
   • DJI’s Agras T100/T70P/T25P carry heavier payloads for spray, spread and lifting tasks, built on over 12 years of agricultural-drone R&D.
   • Sentera’s 6X sensor pairs FLIR Boson+ thermal with six-band multispectral capture (NDVI, NDRE, GNDVI) at 3 cm GSD in a single synchronized pass.
2. Satellite earth-observation analytics (Satellite Earth-Observation Analytics):
   • Planet’s Crop Biomass fuses Sentinel-1 radar with Sentinel-2 and PlanetScope optical data into a daily, cloud-free biomass raster at 3 m and 10 m resolution.
   • The EU Copernicus programme supplies free Sentinel-1 and Sentinel-2 imagery that underpin biomass and vigor analytics across Europe and globally.
3. Field digital-twin platforms (Field Digital-Twin Platforms):
   • Climate FieldView and xarvio FIELD MANAGER combine satellite, weather and field-history data into whole-season field models that generate variable-rate prescriptions.
   • Pix4Dfields hybridizes drone photogrammetry with 30–70 cm satellite imagery to produce vegetation-index, DSM and prescription maps for spray-drone VRA missions.
