HDF-EOS Libraries

HDF-EOS libraries are software libraries built on HDF libraries. HDF-EOS libraries support the construction of data structures: Grid, Point and Swath.

• HDF-EOS2 -- HDF-EOS2 library built on HDF4 (Support Info)
• 
  Description: The HDF-EOS2 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. 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.

• HDF-EOS5 -- HDF-EOS5 library built on HDF5 (Support Info)
• 
  Description: The HDF-EOS5 is a software library designed built on [[HDF5]] to support the same Grid/Point/Swath functionality in HDF-EOS 2 and to the extent possible it will be built with the same calling sequences as the original HDF-EOS 2 library.

• HDF-EOS JNI -- HDF-EOS Java Interfaces
• 
  Description: The Center for Spatial Information Science and System (CSISS)affiliated with George Mason University (formerly known as Laboratory for Advanced Information Technology and Standards, short as LAITS) has been extensively using NASA's HDF-EOS format to be the base file format for storing and processing data from the Earth Observing System (EOS). In responding to the requirement of many Java-based web application server, the center has been using JNI (Java Native Interface) to bridge the C library of HDF-EOS and Java programs. Based on the interface, some object-oriented wrap-ups were developed.

Other Libraries

• he2he5_lib -- a library of HDF-EOS 4/5 Compatibility Layer (unsupported)
• 
  Description: This library allows an application to use an API to handle an EOS Grid or an EOS Swath stored by using either HDF-EOS2 or HDF-EOS5.

• GDAL -- A translator library that supports HDF4 and HDF5
• 
  Description: GDAL is a translator library for raster geospatial data formats such as HDF4 and HDF5. Since HDF-EOS2 and HDF-EOS5 are built on HDF4 and HDF5, this library can also be used to access HDF-EOS data fields.
