Just curious, has anyone gone spelunking in the Magellan SAR EDR (raw) dataset?
https://pds-imaging.jpl.nasa.gov/data/magellan/edr/ Looks like a set of 9-track mag tapes were copied to CD-ROMs for preservation, and at some point the CD files were put online in PDS. In starting to look at it, I realized that lack of knowledge of mag tape volume/label/file/record structure and terminology may impede younger explorers of this dataset. |

I get this result when using Venus Magellan SAR FMAP Left Look Global Mosaic at 225m/px with 600m/px stereo-derived DEM overlayed. This version is 168976x76983 px weighing 13 GB. There is also a version at 75m/px available, but i haven's tried it yet. It's a huge download at 109 GB! And you need lots of RAM to open it. As you may noticed, I prefer white to black rendering of Magellan's data, which renders the surface in much more "photographic" way. |
