Instructions for using ASF MapReady to view Seasat HDF5 files.
Source: ASF Staff
ASF MapReady enables users to view Seasat HDF5 files. To digitally process 1978 Seasat SAR data in 2013, ASF engineers used the most recent version of the Hierarchical Data Format, HDF5. A jpg browse image is included with the products, and the Seasat HDF5 files are viewable through ASF MapReady. Each HDF5 file consists of a metadata group and a data group containing the SAR data as backscatter values in the HH layer as well as latitude, longitude, and temporal data. You can view Seasat HDF5 data by following the recipe on this page.
Seasat data originally was archived on magnetic tapes, and images processed from the tapes were available only as optical images of film strips or scanned digital images. Neither the tapes nor the film allows the quantitative analysis possible with the new digital archive.
