Geodata Discovery Working Group

From OSGeo
Jump to navigation Jump to search

This is a Working Group started by the Public Geospatial Data Committee.

While OSGeo can consider hosting sets of public geodata, (and for the purposes of offering maintained packages of high-quality data for education and demonstration, it probably will), we can compile a set of best practises and references to good prior art for building and maintaining collections of data and metadata.


  • Metadata for collections of geographic information.
  • Providing best practise and prototypes for geodata search facilities
  • Help with providing input into the OSGeo repository/services at
  • Providing 'catalog'/discovery/search services as part of OSGeo activities in promoting access to public domain and open licensed bodies of data.
