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.

• H4CF Conversion Toolkit -- provides CF-compliant access to HDF4 and HDF-EOS2 files
• 
  Description: HDF4 CF (H4CF) conversion API can be used to access various types of NASA HDF4 and HDF-EOS2 files by following CF conventions. We also provide an HDF to netCDF-3 conversion tool that follows CF conventions by using this conversion API.

• 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.

• MDSplus -- A programming interface that simplifies data access and supports HDF5 (Support Info)
• 
  Description: MDSplus is a set of software tools for data acquisition and storage and a methodology for management of complex scientific data. MDSplus allows all data from an experiment or simulation code to be stored into a single, self-descriptive, hierarchical structure. The system was designed to enable users to easily construct complete and coherent data sets. The MDSplus programming interface contains only a few basic commands, simplifying data access even into complex structures. Using the client/server model, data at remote sites can be read or written without file transfers. MDSplus includes x-windows and java tools for viewing data or for modifying or viewing the underlying structures.

• hdf5read -- A Fortran-90 programming interface that simplifies data access and supports HDF5 and HDF-EOS5 (Support Info)
• 
  Description: This module is written to read user selected datasets and attributes from HDF5 and HDF-EOS5 datafiles for further processing without having to go into the details of reading such files. The user only needs to know what he/she wants to read and of what data type (integer, real, string, ...) and rank (scalar, vector, ...) it is. The package includes a sample data file and a sample program showing how the module has to be used. The routine have been tested on only a few HDF5 and HDF-EOS5 files and does certainly not cover all possible types of data in such files.

• 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.
