IVOA Interop. Meeting, October 2005
VisIVO work in progress
Implementation:• Java external libraries interface• New graphic tools (sampler,
cutting and projection planes…)• 3D Vectors support• Multiple scalars/vectors support
Multiplatform support:• Linux porting
Interoperabilty:• Aladin + Topcat in the
AstroGrid framework• AstroNeural tool for
clustering and data mining in high dimensionality spaces
• Access to web services
IVOA Interop. Meeting, October 2005
Apache Axis is an implementation of the SOAP ("Simple Object Access Protocol") submission to W3C
VisIVO and VizieR communication layer
VizieR Catalogues Web Service
why Axis C++?• C++• Open Source• developed for Linux and Windows• stable• reliable• many web services are developed
using Axis• Apache Software Fundation
IVOA Interop. Meeting, October 2005
VisIVO and Aladin
Aladin is an interactive software sky atlas allowing the user to visualize digitized
images of any part of the sky, to superimpose entries from astronomical catalogs
Aladin can be controlled via commands
sent to its standard input
Using a pipe it is possible to interact
with it from VisIVO
Objects can be selected using a picker
and passed to Aladin to perform
further operations
IVOA Interop. Meeting, October 2005
AstroNeural
Data mining algorithm, in collaboration with the Universities of Napoli
and Salerno, AstroNeural project.
Aims and applications of AstroNeural:
User friendly tool to perform clustering and data mining in high dimensionality spaces
• Clustering & pattern recognition in high dimensionality spaces
• Visualization (VisIVO)• Classification• Parametrization of images• Modeling of massive data sets
