Datastar Stress Index (DSI)
Datastar Computational Analyst (DCA) quantifies stress information non-subjectively using the Datastar Stress Index (DSI) as a standard of measurement.
Datastar Stress Index for Fruit Crops
DSI is an objective measurement of stress from insignificant (no stress) to severe stress
DSI is a number from 1.00 to 3.00 with 200 divisions - 0.5% granularity
Provides required precision in measuring stress
For mapping products, DSI is also presented as a three-level color presentation
DSI is the basis for all DCA products
