The South Pole of the Moon – Shackleton Crater   6 comments

The South Pole of the Moon is at 10 o’clock on the rim of Shackleton Crater.  20 meter data from a 1500 x 2100 original.  42 kilometers x 30 kilometers. It wouldn’t be a fair Marathon, though, the change in height here is 4.6 km.  It’s a long way down, and the walls of the crater are quite smooth.  This is corrected from an earlier image that was exaggerated in Z.  This has the to scale proportions.

From overhead, gray tone shading by height.  A correct representation.

The casting is 5″ x 7″ and a bit over an inch thick.

  1. Who needs Armstrong?

  2. I posted a comment in a post you made about your workflow and this is the original post I was referencing. Where can I find this height map data? I’m looking for a high resolution height map of Shackleton Crater and the surrounding area so I can make an accurate 3d model of it. Can you help me out with finding the data and/or the images needed for making a 3d model? Thank you much!

  4. Can somebody please explain where those lines on the crater come from?

    • This was an early (2010) release of the data with a low number of orbits to use to make the model. The lines are seams. The passes are only 20 meters wide. For a variety of reasons, the passes do not line up exactly, and the stitching of the data produces the lines. Later releases (2014) (~4000 orbits a year) with more passes have eliminated the lines. I will try again.

  5. The scan width for the Laser Altimeter is about 20 meters. Each orbit scans a different slice, in a different orientation, as the moon rotates underneath the polar orbit. The software that stitches together the slices does the best job it can (this is an early data release, so there are not a lot of orbits) and produces seams with bumps, which are the lines in the model. Data from 2014 and later is much cleaner, as there are now many thousands of scan passes of the poles.
