HDF-EOS libraries

HDF-EOS is a software library that is an extension of National Center for Supercomputing Applications (NCSA) HDF.
The library supports the construction of new data structures: Grid, Point and Swath.

• HDF-EOS2 -- HDF-EOS library built on HDF4
• 
  Detailed description: HDF-EOS 2 is a software library designed built on HDF4 to support EOS-specific data structures, namely Grid, Point, and Swath. The new data structures are constructed from standard HDF data objects, using EOS conventions, through the use of a software library [1,4]. A key feature of HDF-EOS files is that instrument-independent services, such as subsetting by geolocation, can be applied to the files across a wide variety of data products. The library is extensible and new data structures can be added.

• HDF-EOS5 -- HDF-EOS library built on HDF5
• 
  Detailed description: The HDF-EOS 5 library written in conjunction with HDF5 and which uses HDF5 functionality, will necessarily be a rewrite of the HDF4-based version. The new HDF5-based library will support the same Grid/Point/Swath functionality and to the extent possible it will be built with the same calling sequences as the original library.

• CV -- reads the HDF and HDF-EOS files in native ISIS cube format
• 
  Detailed description: The "cv" (Cube Visualization) program has been used for a number of years as part of the ISIS image processing system (Integrated Software for Imagers and Spectrometers). "cv" has recently been enhanced to directly read the HDF and HDF-EOS file formats in addition to the native ISIS cube format. This includes data from the Terra and Landsat 7 satellites. Files based on HDF Version 4.x are supported; files based on the new HDF 5.x are not supported. "cv" is also now packaged so that it can be run without installing the rest of the ISIS software system.
