visivo work in progress
VisIVO work in progress
  • Interoperabilty:
  • Aladin + Topcat in the AstroGrid framework
  • AstroNeural tool for clustering and data mining in high dimensionality spaces
  • Access to web services
  • Implementation:
  • Java external libraries interface
  • New graphic tools (sampler, cutting and projection planes…)
  • 3D Vectors support
  • Multiple scalars/vectors support
  • Multiplatform support:
  • Linux porting
visivo and vizier communication layer
VisIVO and VizieR communication layer

VizieR Catalogues Web Service

Apache Axis is an implementation of the SOAP ("Simple Object Access Protocol") submission to W3C

why Axis C++?

  • C++
  • Open Source
  • developed for Linux and Windows
  • stable
  • reliable
  • many web services are developed using Axis
  • Apache Software Fundation
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 catalogsVisIVO and Aladin

Objects can be selected using a picker and passed to Aladin to perform further operations

Aladin can be controlled via commands sent to its standard input

Using a pipe it is possible to interact with it from VisIVO

astroneural
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

Aims

Applications

Astrophysics

Genetics

Geophysics

High energy physics

Atmospheric physics

Etc.

  • Clustering & pattern recognition in high dimensionality spaces
  • Visualization (VisIVO)
  • Classification
  • Parametrization of images
  • Modeling of massive data sets
