The Planetary Data Surface : Services and Portals (PDSSP) is a geospatial data and services center dedicated to studies and research on planetary surfaces. The aim of the PDSSP is to facilitate access to data and contribute to the creation of products and services by adding value to existing space data .The facility will also serve as a mechanism for the planetary science community to share information and better address the challenges of digital technology. It will be part of the national, European and global landscape, working closely with PSUP (Planetary Surface Portal), VESPA (Virtual European Solar and Planetary Access) and SSHADE (Solid Spectroscopy Hosting Architecture of Databases and Expertise) services.
The PDSSP offers a search portal to help disseminate and use high value-added data for planetary surfaces. This includes spectral data, geological maps, high-resolution images and DEMs and other useful information for the scientific community, students and general public interested in planetary studies.
The PDSSP also contributes to collaboration and interoperability between different thematic projects in the field of planetary surfaces, by providing tools, services and expertise to facilitate information exchange and collaboration between scientists and researchers.
The PDSSP's mission is to bring together existing facilities to serve the planetary science community. It is based on the establishment of a spatial data infrastructure for planetary surfaces, providing access to its data. It aims at providing added value, particularly in terms of data and services in fields where data centers do not exist or need to be developed, and in terms of links with European and international systems. The aim is to strengthen the planetary science community, in synergy with the other structures in the field, by giving it access to the data it needs for its research, in accordance with the access standards.
The STAC-PLANET project is the flagship initiative of the PDSSP in this first phase. It is based on the adaptation of terrestrial standards from the Open Geospatial Consortium (OGC) to planetary surfaces, providing unified access to planetary data. STAC-PLANET is currently under development at CNES as a contribution to the PDSSP project, and its first version is expected to be released by the end of 2026.
Another tool of interest in this context is the VESPA geospatial portal (https://padc-findme.obspm.fr). This environment is essentially a GIS based on Virtual Observatory procols and standards, which connects georeferenced data collections accessible through the EPN-TAP protocol. The tool allows quick identification of observing configurations, overlaps and superpositions between data products from various collections, including external footprints.
STAC-PLANET takes a complementary approach, offering a GIS fully compatible with Earth Observation tools and standards, while adding VO services that translate Earth Observation protocols into VO-compliant interfaces, making planetary data accessible to both communities within a single integrated framework.
