This appears to be a new global color Viking image mosaic. Too big for me to handle, so I look forward to seeing what others do with it! The browse preview looks quite lovely.

unfortunately the usgs servers are maxing out at about 300Kb/ sec (with about 200K as the average)
at 12 gig this is a 12 hour dl on a 30 meg cable connection |

Emily, just an idea, please. Could there be a downloadable version of this gorgeous map put online by TPS on its website as JPEG images : 1 global half resolution + 2 hemispheres left/right full res (to be mosaicked by users if needed) ? This would be a real help much appreciated from us as TPS members... Thanks so much again in advance if you can find a solution, please, and with warmest regards, VM |

I don't plan on hosting the full-resolution data, but with the help of Fred Calef I have posted here a version with a resolution of 2.5 km/pixel in PNG format, suitable for serving as the base of a global map. It is 52 MB and 8536 pixels wide.

what do you know the dl speed of the cub is now at 1.9 M/s
2 hours VS 12 hours but this is just a colorized version of the same mdim basemap good for making a control network for the themis data and CTX images |

One of my long-running projects has been reprocessing Viking Orbiter mosaics. One of my eventual goals is to recreate the mosaics featured in Viking Orbiter Views of Mars. The data's pretty great when it's cleaned up and frames assembled digitally, so I think it'd be great to see an "updated" version of that book. I have a growing Flickr gallery of completed mosaics. I'll post a couple of my favorites here.

Here's a 15-frame mosaic of the region northwest of Hellas Basin. There is a missing chunk at top center that appears to have been filled in with the official NASA release of this image, but I'm not sure where they pulled the data from. A neat feature that the official version misses is some high-altitude clouds along the horizon at the bottom left corner.

It amazes me home much we missed back in the 80s!
Well done!! Its also nice to see the correct colour and not the blood red over saturated images of the 80s. |

Stunning. The wide-field views of Mars from the VOs are still some of the most dramatic and beautiful ever captured.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

This is an awesome mosaic and one thing I like is that this is not a low phase view. Examining the terminator in hi-res global views of planetary bodies is usually interesting. It would be particularly interesting to see hi-res global views of Mars at high phase angles - the limb/atmosphere would be interesting in these views (anyone from the MOM team reading this ? ;-)).
