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
