Viewing Geometry of AVHRR Image Composites Derived Using Multiple Criteria

The U.S. Geological Survey currently generates composites of AVHRR imagery based on a single objective-maximizing the Normalized Difference Vegetation Index (NDVI)-as a means of reducing cloud contamination. Our research supports the findings of others that, i n some cases, NDVI is maximized at the expense of optimal viewing geometry; that is, satellite… (More)
