    • The ECS Standard Data Format: HDF-EOS • HDF-EOS is an extension of NCSA’s Heirarchical Data Format (HDF) • Includes ECS Core Metadata as an attribute stored in ODL format (allows geolocation information 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 POINT GRID SWATH Spatially oriented data with a known mathematical transformation between row/col and lat/long Time- or track- oriented data with geolocation per data element or scan line Table Data with no predetermined orientation in time or space. Geolocation and time supplied with every point 97E021 d-12
