Abstract

The application of Geographic Information System principles and tools on planetary data is by now a well-established practice in the planetary community. At the same time, the last decade saw a progressive development of Virtual Observatory (VO) techniques and tools (e.g. Erard et al., 2014), which allow for enhanced data search, discovery and visualization.

The growing amount of multi-mission, multi-experiment data over several Solar System objects will greatly benefit from an integration of the GIS and VO approaches.

In this respect, the use of existing protocols, their improvement and eventually new ones to allow spatial interoperability in GIS/VO realms are going to be explored, using as targets planetary bodies with the required data coverage and complexity. Particularly, the inclusion of geographic and cartographic elements in Flexible Image Transport System (FITS) labels, in addition to the already existing ones in PDS data is being developed (Marmo et al., this meeting).

Closing the gap between these two approaches in data access and analysis has potential not only for easier data discovery and exploitation, but also to broaden the scientific community working on planetary data and potentially developing new, cross-discipline use cases. Typically GIS systems are used by surface (geo)scientists, but they might well become appealing for the atmospheric science and plasma-magnetosphere communities, if linked with VO tools.

We plan, within the Europlanet RI VESPA activity, to establish links and federation between suitable existing services, in addition to those in development, in order to be cross-queried and accessible.
