Dawn data in the PDS Options

Hey folks, Christmas came just a little bit late this year...

DAWN DATA RELEASE: LEVEL 1A DATA FROM APPROACH AND SURVEY

The Dawn project has created a public website that is available to serve the cruise and Vesta data sets that have been delivered to the Planetary Data System (PDS) while the data are still under review. Data are available from all three Dawn instruments, the Framing Camera (FC), the Visual and Infrared Mapping Spectrometer (VIR), and the Gamma Ray and Neutron Detector (GRaND). The data that are currently available are raw data, in engineering units, sometimes referred to as EDRs by the PDS or as NASA level-1a data. Additional data sets will be added when they are submitted to the PDS.

The Dawn website is located at:

Users of these data should exercise caution. Invariably there will be errors or omissions in the documentation. Please report any problems...

It is a LOT of data. Just the Vesta Approach includes about 2000 FC images! Wow!!!

I think that the first thing I'm going to work on is that approach sequence/movie that I wish I'd had in real time. The rotation of Vesta through the image sequences makes color composition very hard, but I am sure there are people here who are up to it. I hope someone here can come up with a pretty color global shot that I can put into a comparison montage!

You might want to take a look at this regarding shape files..

This shape is from Dr Robert Gaskell produced after the survey orbit.
As i remember, this shape use the old system coordinate before the first change (Claudia as prime meridian) by Dawn Team.
I made (year ago) a conversion for cmod file (I choose cmod because i think it is very easy 3d file structures to read) here:

But even with shape i have a problem to build small mosaic Vesta rotates very fast and condition of illumination change as well.

I'm finally going to take a fairly detailed at the Vesta data and the first step is a shape model that the images will be draped over. I have the files mentioned above. Sarunia's cmod files are probably easier to handle but they are not the highest resolution available.

The highest resolution files can be downloaded using the link posted by Doug but they are in a format that I need to convert to something else (possibly cmod). After exploring the data I'm getting the impression that converting them is going to require considerable work, possibly some programming (I have not found a converted version of the hi-res stuff anywhere). Yet the lower resolution versions have been converted to at least cmod. Does anyone know of any utilities that can read/convert this stuff? I haven't found any easy solution but I wouldn't be surprised if I have missed something.
