The ECS Standard Data Format: HDF-EOS
Table
• HDF-EOS is an extension of NCSA’s Heirarchical Data Format (HDF)
• Includes ECS Core Metadata as an attribute stored in ODL format (allows geolocationinformation to be conveyed)
• Format is standardized and self-describing
• Files are manipulated and services applied via an API
In addition to standard HDF structures, 3 additional structures have been added: Point, Grid,and Swath
Data with no predeterminedorientation in time or space.Geolocation and time suppliedwith every point
Spatially oriented data with aknown mathematicaltransformation between row/coland lat/long
Time- or track- oriented data withgeolocation per data element orscan line
POINT GRID SWATH
