Vegetation Satellite Provider: MAXAR
Applications
vegetation monitoring with soil adjustment
red-edge vegetation analysis
agricultural monitoring
sparse vegetation assessment
soil background minimization
Quick Stats
Category: vegetation
Sensor: GeoEye-1
Provider: MAXAR
Bands Used: 2
Description
OSAVI2 is a variant of the Optimized Soil Adjusted Vegetation Index that uses red-edge bands (750nm and 705nm) instead of traditional NIR and red bands. This modification improves sensitivity to vegetation changes while maintaining the soil brightness correction factor of 0.16, making it particularly effective for vegetation monitoring in areas with variable soil backgrounds.
