SuperView-1 TSAVI
Transformed Soil Adjusted Vegetation Index for SuperView-1
Vegetation Satellite Provider: SPACEWILL
Applications
Vegetation monitoring in areas with exposed soil
Agricultural crop assessment
Biomass estimation
Leaf Area Index (LAI) measurement
Sparse vegetation mapping
Quick Stats
Category: vegetation
Sensor: SuperView-1
Provider: SPACEWILL
Bands Used: 2
Description
A vegetation index designed to minimize soil brightness effects on vegetation measurements. TSAVI requires knowledge of the soil line parameters (slope and intercept) for optimal performance.
