Virtual Observatory Integration of OGC geospatial data and services.

Résumé

Planetary exploration missions produce a wealth of geospatial data, largely from imaging experiments. Data discovery and access can rely on Terrestrial geospatial standards [1], or Virtual Observatory (VO) approach of EuroPlanet-RI H2020 VESPA [2]. Integrating the two is the aim of VESPA Surface Task. VO-GIS interoperability facilitates discovery, display, access and use of geospatial data. In combination with non-surface imaging datasets, it has a potential for interdisciplinary science. We provide geospatial data through VO (Virtual Observatory) TAP (Table Access Protocol) on a dedicated server. Our service runs GAVO DaCHS (Data Center Helper Suite) and is registered with the IVOA (International Virtual Observatory Alliance). Currently exposed tables are: (a) usgs_wms - VO/GIS access to USGS-served WMS (Web Map Service) [3]; (b) crism - CRISM data on [4], with a JavaScript viewer where a spectrum selected on a preview can be visualized in a browser or broadcasted to VO tools; (c) mars_craters - Mars Crater Catalog [5]. Footprint polygons in crism and mars_craters can be sent to the VO viewing tool Aladin. Support from the latter for complex polygons will allow for improved, GIS-like search and data access capabilities. The exposure of additional planetary OGC services is planned. Current work involves the development of a Desktop GIS (QGIS) plugin to enable VO-access and expanding the range of datasets suitable for surface mapping and analysis. All of our developments are Open Source and our code and tools are available on the VESPA GitHub organization page and repositories therein [6]. References[1] Hare et al. (2015) LPSC XLVI, #2476.
