The One-Minute Land Ecosystem Classification product file is stored in Hierarchical Data Format (HDF). HDF is a multi-object file format for sharing scientific data in multi-platform distributed environments. HDF files should only be accessed through HDF library subroutine and function calls, which can be downloaded from the HDF web site. All of the parameters are stored as Scientific Data Sets (SDS's) within the HDF file.
