Challenges for coordinating data aggregation for
different instruments and platforms

• Different data delivery formats
• Varying horizontal and vertical resolutions
• Varying time sampling intervals
• Varying methods of data delivery
• I.e. telemetry - wireless, satellite

Data Formats

• Real-time formats
• typically a standard format such as WMO,
  which is utilized over the GTS system. Although
  it may be a proprietary manufacturers data
  format. Some systems, like on Explorer of the
  Seas, has enough bandwidth to download large
  portions of the data every 15 minutes using
  rsync.
• Near real-time formats
• data formats that may include QA/QC. These
  formats vary from tables produced on web pages
  and traditional flat ASCII files, to
  self-describing binary formats such as NetCDF.
• Archive formats
• typically self-describing data formats in
  ASCII,GIS or NetCDF. Web services tools now
  provide methods to have the user display and
  download the data in the several different
  formats.

Data delivery methods to users

• Site specific website pages query and download
• Community portal web GIS at
• CSV(Comma Separated Value) files (flat ASCII
  format)?
• netCDF files
• DODS/OPeNDAP query interface
• ESRI ShapefilesWFS (Web Feature Service)?
• Web Service query with XML or SOAP response
• Google Earth
