The SPOT satellite constellation offers acquisition and daily revisit capacity for anywhere in the world. SPOT produces two high resolution optical images. The multispectral mode is in the red, green and infrared bands of the EM spectrum. The panchromatic mode is a single wide band in the visible part of the spectrum with higher resolution.
In approximately 20 years - a very long time for any satellite to remain operational - the SPOT 2 satellite collected a total of 6.5 million "scenes" covering almost 23.4 billion km2, i.e. approximately 46 times the complete Earth's surface.
