In plain English
What it measures. Daytime visible images of the land surface that have been geometrically corrected so features line up properly on a map.
How it's made. Taken by the AVNIR-2 camera on Japan's ALOS satellite and processed into an ortho-rectified image product. (The provided description is very brief.)
How & where you'd use it. Map-ready land imagery of this kind is generally used for land-cover mapping and observing the surface, though the supplied text gives little detail.
