IVOA Interop. Meeting, October 2005 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 Multiplatform support: • Linux porting Implementation: • Java external libraries interface • New graphic tools (sampler, cutting and projection planes…) • 3D Vectors support • Multiple scalars/vectors support IVOA Interop. Meeting, October 2005 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 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 Objects can be selected using a picker and passed to Aladin to perform further Aladin can be controlled via commands operations sent to its standard input Using a pipe it is possible to interact with it from VisIVO 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 Aims • • • • • Clustering & pattern recognition in high dimensionality spaces Visualization (VisIVO) Classification Parametrization of images Modeling of massive data sets Applications Astrophysics Genetics Geophysics High energy physics Atmospheric physics Etc.
