Agriculture monitoring

Vegetation indices, crop maps and parcel alerts through the season, from optical, hyperspectral, thermal and SAR imagery.

Indices

Index	Formula	Shows
NDVI	(NIR − Red) / (NIR + Red)	Vigour and green cover
NDRE	(NIR − RE) / (NIR + RE)	Chlorophyll and nitrogen in dense canopies
EVI	2.5 (NIR − Red) / (NIR + 6 Red − 7.5 Blue + 1)	Vigour where NDVI saturates
SAVI	1.5 (NIR − Red) / (NIR + Red + 0.5)	Early season, sparse cover over bright soil
NDMI	(NIR − SWIR) / (NIR + SWIR)	Water content of the canopy
LAI	Modelled from reflectance	Leaf area per unit of ground
LST	Thermal infrared	Water stress and irrigation need
Soil moisture	SAR backscatter	Surface moisture, through cloud

Threshold classification on a single 5.2 m scene; production maps add training data, several dates and field validation.

01
Crop type maps
Parcels classified by crop from the season’s time series.
02
Growth curves
Index per parcel, date by date, against previous seasons.
03
Stress alerts
Parcels falling behind their neighbours or their own history.
04
Management zones
Within-field zones for variable-rate fertilising and seeding.
05
Irrigation
Water demand and stress from surface temperature and moisture.
06
CAP checks
Declared crop against observed crop; ploughing, mowing and harvest dates.
07
Damage assessment
Hail, flood, frost and fire damage mapped per parcel.
