Sensor: WorldView Legion

Provider: MAXAR

Bands Used: 3

Description

TCARI/OSAVI 705,750 is a modified version of the TCARI/OSAVI index that uses the red-edge bands at 705nm and 750nm instead of traditional red and NIR bands. This modification improves sensitivity to chlorophyll content estimation while reducing the influence of leaf area index and soil background.
