VOQuest is an application that provides access to services
implementing a specific data model. To do so, VOQuest makes use of a
bunch of VO standards and protocols like ADQL, VOTable, SkyNode and
PLASTIC. Besides that, this tool is able to interoperate with existing
VO applications like VOSpec, Topcat and Aladin to relegate some specific
functionality already present in such tools in mature state.
As a technology demonstrator this application, and the architecture
hidden beneath it, is at a prototype stage.

TOPCAT is an interactive application for manipulating tabular data
such as source catalogues, increasing in popularity with VO and
non-VO users. Version 2.0, released Feb 2006, provides considerably
improved visualisation facilities including histograms, density
maps and 3-d plotting. A demonstration of these new features
will be given.

> > | WCSFixer | |||||||
WCSFixer was one of high-priority apps identified by the NVO
Science Steering committee and provides a method for solving/improving
the WCS of images. It uses standard VO protocols for accessing reference
catalog data and makes use of legacy software (IRAF) to do the computation.
Additional VO Tools (i.e. the STILTS toolkit from Mark Taylor) are used
to manage VOTables in the legacy environment and the webapp itself is
simply a CGI-POST script with embedded JavaScript to drive the interface,
however standard SOAP/WSDL web services and desktop client applications to
call it remotely as a commandline task will soon be available as well.
It is currently undergoing revision with a new version expected in time
for the meeting. Community usage has exposed data-quality problems/issues
for real-world applications, as well as limits imposed by choice of
algorithm.

Using mapping packages from the geophysics community and the World Wind
interface developed by NASA, we have created a number of tools for visualizing
astronomical data on the sky. The interface projects imaging data as well as
footprint maps (coverage, overlap and background) onto the sphere and allows
users to scan around the sky, zoom and overlay different data sets on top of
each other. Images are generated in a range of resolutions, dynamically
served to the client using a Web Mapping Server (WMS) based on the current
viewing window and projected onto the sphere. Our WMS server at Pitt is
currently serving maps for the fourth Sloan Digital Sky Survey data release
(SDSS DR4) and the Wilkinson Microwave Anisotropy Probe full sky cosmic
microwave background map as well as coverage maps for the SDSS DR5 and the
FIRST radio survey. Since we went live in mid April we have served nearly
90GB of imaging to roughly 80,000 unique IP addresses from all over the globe.

how the VO's SIA protocols exactly complements the internal geometry
capabilities of SkyView.

Databases generated with Saada are designed to host heterogeneous data
collections. In this context, data can be selected by providing collections
with some common interface such as a common spectral coordinate system and by
expressing contraints with UCDs.

The Sampo project has developed a prototype general purpose VO application using standard IVOA protocols and the ACR facade from Astrogrid for access to external VO resources. VODA allows browsing and resource discovery in the VO and the management of a Virtual Directory of data references. The Virtual Directory forms a local, presistent personal view of the VO where referenced data sets may be downloaded or directly passed to visualisation tools such as Aladin, fv or DS9. We are currently experimenting with the use of Plastic as a general purpose connection between VODA and VO tools. VODA also offers the possibility for client-side applications to access VO resources via the Virtual Directory. We will describe the motivation and implementation experiences as well as giving some simple examples of VODA in action. . | ||||||||
