SMI = "Standard Mapped Image" (I think) and there are 8640 pixels at the
equator and 4320 between the poles. From that, there are 8640/360 pixels
per degree (at the equator) or 0.041667 degrees per pixel. From that you
can construct a grid which corresponds to the lat and lon at the center
of each pixel.
