Dear Even, Ivan,
Point taken on the self-consistency of the products.
GeoTransform indeed appears incorrect, at least for NDVI.

looks at lon

So the -180.00xxx (half pixel west of -180) reported by gdalinfo for upperleft
corner of upperleft pixel is fine,
though we realize that this g

Very good examples.
