CAVIS Bands
•
CAVIS – Our internal acronym, and our scientists love acronyms
- Sensor designed to measure atmosphere and normalize imagery and improve
image quality
- CAVIS retrieves atmospheric Aerosol and Water Vapor at the same time as the
image, making reflectance calculations easier.
- Also allows to create accurate metadata on clouds, snow and ice
- CAVIS designed to improve imagery yield especially in cloudy areas
-
PERF WorkShop
C – Map Clouds
A – Measure Aerosols or Particles in atmosphere that affect image quality
V – Measure Water Vapor that affects image quality
I – Map Ice and differentiate it from clouds and snow
S – Map snow and differentiate it from clouds and ice
