This section gathers various actions to access data content from EPN-TAP services.

VESPA user search interface / portal

• The main user interface is located here:
It queries all services at once (other modes are available), formats the results, and connects with VO tools and other environments (ObsParis)
Roadmap for developments: VESPA user interface

• A local VESPA portal can be installed on your machine. This is intended to access services which are only available locally (e.g., on a Virtual Machine) and are not exposed on the Internet.

• Generic TAP clients are also usable (e. g., TapHandle, TAP Library, TOPCAT, and Aladin from v10) but do not provide specific support for EPNCore-based services

EPN-TAP library(ies)

EPN-TAP client libraries have been developed and  included in some VO tools: CASSIS, 3Dview, + AMDA in the future (IRAP/CNRS)

Users requirements / use cases (obsolete?): VESPA Clients specifications
Library specifications doc
: VESPA EPN-TAP Library specification
Java implementation
PHP/JavaScript implementation
: in dev, TBD

Added SAMP plug-ins

Several tools have been updated so they're able to send / receive data through SAMP:

• A plug-in provides SAMP connectivity to QGIS (Jacobs / GEOPS)
Users requirements: jra-t4-requirements
Page and links: jra-t4-tools-qgis-plugin

This works under Debian. A pre-packed Virtual Machine is available from JacobsUni with Debian/QGIS/plug-ins installed, for use with other OS
A working version under Mac OS has been seen in April 2018.


• A plug-in provides SAMP connectivity to ImageJ (ObsParis) - currently in input only
Installation and use:

• MATISSE can now receive data via SAMP (ASI/ASDC): Update on integration MATISSE-VESPA

• Autoplot can now receive data via SAMP (Iowa Uni): Available tools

Google Sheet Add-on

Allows to query EPN-TAP services from on-line documents: easy access interface through on-line Excel-like sheet (Graz)
The preview of the tool can be found here >>
A short tutorial describing basic features and usage can be found here:
(included in D6.9)

Links to various environments (tutorials)

Are being defined:

EPN-TAP files retrieving interface

A set of web services providing file URL in JSON format, intended for pipeline processing
See this page: File grabbing interface (fgi)

Python interface

Limited to grabbing VOtables sent from VESPA
Info here: VESPA usage for non VO people
Baptiste's exercise during DPS/EPSC 2016 / Astropy for Planetary Science session ("SAMP in python .ipynb")

IDL interface

Limited to reading VOtables downloaded from VESPA
Info here: VESPA usage for non VO people
Stéphane's exercice to read VOtables from IDL - tuto TBD
