Ground/soil associated with ___ TCARI/OSAVI values

Question

BlackTom AI · Accepted Answer

Question restatement: Ground/soil associated with ___ TCARI/OSAVI values. Options are: Negative or Positive.
Option 1: Negative. This aligns with how TCARI/OSAVI behaves over bare soil or sparse vegetation where soil background dominates the reflectance. In such cases, the index values tend to be low or negative because the chlorophyll-related signal is weak and soil brightness effects can reduce the TCARI/OSAVI combination, leading to negative readings.
Option 2: Positive. A positive TCARI/OSAVI value is typically associated with healthier, denser vegetation where chlorophyll content is high and the vegetation signal dominates. If the ground is bare soil or not vegetated, we would not expect positive values; instead, the index would lower or become negative due to soil background. This makes the positive choice inconsistent with bare ground scenarios.
Additional nuance: TCARI/OSAVI is designed to minimize soil brightness influence while enhancing vegetation signal; however, when ground cover is minimal, the index tends to reflect the soil characteristics, which often drives values toward the negative side. Conversely, substantial vegetation cover shifts the index toward positive values because of strong chlorophyll absorption in red and high reflectance in near-infrared bands, which is captured by TCARI/OSAVI.
In summary, the ground/soil condition described corresponds to negative TCARI/OSAVI values, whereas a positive value would indicate more robust vegetation presence rather than bare ground.
