Cassini image database & updates, And notifications of PDS data releases Options

[Bjorn Jonsson]

I have noticed that the January 1, 2007 Cassini PDS release is already available, see http://pds-imaging.jpl.nasa.gov/data/cassi...assini_orbiter/

I haven't downloaded all of the imaging data and I'm just beginning to digest what I already have but there are some beautiful images of Enceladus' plumes and satellite mutual events, images of the G and D rings and interesting images of Saturn's nightside and fairly good Iapetus images.

Radar and VIMS is also available.

All in all a nice 'Christmas gift' .

I just went through the process of creating an index page for Dione, using the 2 pixels per degree (=228 pixel diameter) size cutoff:
http://planetary.org/data/cassini/dioneattempt/
WARNING: to view this page requires you to download about 42 MB of data.
[Note: I didn't bother uploading the full-size images, only the thumbnails, so the images won't link to anything. Also, I didn't yet include all the fields I mentioned in my previous post; I did intend to include the filters and stupidly forgot. Next time around they'll be in there.]

This included more than 500 images, but after seeing the results I don't think it was enough. Cassini has so danged many filters that those 500 images were for a relatively small number of distinct observations (22), most of them on nontargeted flybys; the query did not pull in nearly as many global shots of the moon as I was hoping to get. So I think I will back away and try the 1 pixel per degree cutoff next time.

What do you think of the layout, with one observation per line? I think I will reduce the size of the thumbnails next time. They are currently 256 pixels -- I think I will reduce to 128 or even 100.

I used IMG2PNG to convert these, and did calibration, but the calibration didn't seem to work for the WAC images for some reason.

Comments?
