Astropedia:Main

From Astrodocs

Astropedia is a planetary data and cartography catalogue housed by the USGS Astrogeology Science Center. For users and scientists that require access to planetary geospatial data, Astropedia serves as a data portal that allows for easier ingestion, presentation and delivery of cartographic products in an efficient and consistent manner. Astropedia uses a PostgreSQL Database with PostGIS add-ons, an Alfresco Document Management System (DMS) as a data repository, Openlayers for web-based interactive mapping, and Mapserver as a WMS to serve the planetary base maps.

Goals

Astropedia provides a onestop-shop, web-accessible data portal that can be searched using multiple methods including: target information, geospatial coordinates, mission or instrument keywords, author and organization, as well as additional descriptive information available from the metadata. The USGS Astropedia data portal has several goals:

  • Quick access to current and featured data
  • Robust searching
  • Data downloads in various formats
  • Viewable metadata
  • Interaction through web map services
  • Cross-links to ancillary and relevant data

These goals are accomplished through extensive use of well-documented, standardized metadata and several open-source tools listed above.
