Mmmm,
I'm not so confortable with my previous answer because I assumed you measured those 440m on the "wrong" image... After reviewing again the data for image R1500822 on the MSSS site (http://www.msss.com/moc_gallery/r10_r15/im...5/R1500822.html), I have found the following. Our assumption about 1.45 m/pixel for that image comes from the parameter: "Scaled pixel width: 1.45 meters" But R1500822 has actually two versions, one map-projected and another not. The "map-projected" version is the nice one we all have seen here and on another places. But those 1.45 m/pix refers to the NOT map-projected image i.e. the "raw" picture, and is actually the *horizontal* resolution of the picture. The vertical resolution is 1.45 * 0.43 (pixel aspect ratio) = 0.6235 m/pix. The map-projected image may have a different scale. (edited to include reference picture) |
