Science DATA ACCESS, DISCOVERY AND VISUALIZATION

There are a large number of archive sites and visualization packages that you can use to achieve your science analysis goals. As far as I am aware the CADC tool OCTET is the ONLY query tool that will provide links to spatial associations of observations [observations of the same region of the sky taken at different wavelengths where the observations may come for different observatories].  OCTET is freely available to anyone in the world who wants to use it... you don't even need a CADC account [which are free to the world community also].

Archive Tools:

OCTET

A multi-mission, multi-wavelength, Association query tool for publicly available VO datasets.

By default the OCTET displays imaging data using Aladin.  Aladin is written in JAVA and is a good choice for users who need to deploy over a network [like from within and archive query tool like OCTET]. However, Aladin is a more of a catalog exploration and image view then a full out 'data visualization' system.  For really complete data visualization you may have to write your own software, but a few reasonable choices do exist. 

Some links to visualization software:

DS9

Good for single plane and cube data. Nice remote access. Some VO archive tools but not completely integrated with visualizer.

Aladin

Excellent for online catalog searching. Not so good analysis tool [pretty bad really]. Doesn't handle Cube well.

Karma

Excellent for cube of data, feature rich, lots of visual impact. Not much actual analysis capability

GAIA::SkyCat

Good basic image display tool with catalog interface with some builtin analysis capability. GAIA 3D is being developed at JCMT to provide full 3D data support.
