• Organized by topic
October 1, 2003http://sofia.usgs.gov
Overview - Data Exchange (cont.)
• Direct access to data sets as well as:– Format information– Methodology– Location map– Site listings– Photos– Project information

SOFIA Information Management
• Background
• Overview of website
• Metadata• Future of SOFIA
October 1, 2003http://sofia.usgs.gov
SOFIA Metadata
• Federal Geographic Data Committee (FGDC) metadata standard used from the beginning
• Survey of project chiefs showed they felt metadata was important to their work, but did not have time to create it themselves
• SOFIA Metadata project component added
October 1, 2003http://sofia.usgs.gov
Metadata Methodology
• When a new project is authorized, a metadata record is created
• As the project progresses and data becomes available, the metadata record is updated and another record is made for the data exchange pages Chart (modified) from www.fgdc.gov
October 1, 2003http://sofia.usgs.gov
Metadata Methodology (cont.)
• Metadata created using Spatial Metadata Management System (SMMS) from Intergraph
• Then parsed through USGS metadata parser, mp
• Output in three formats:– html (standard & FAQ)
versions
– text
– xml
October 1, 2003http://sofia.usgs.gov
Metadata Methodology (cont.)
• Once a metadata record has been created, it is uploaded to the SOFIA server
• In order to index the metadata records:– Metadata server (zserver) is
stopped
– Database is reindexed
– Metadata server restarted
• Server software is separate from web server software
October 1, 2003http://sofia.usgs.gov
Metadata Methodology (cont.)
• New records are now available via both the SOFIA search and FGDC search
