This page describes available tools that can be used with data you retrieve from us or other data centers. NASA is not endorsing any of the commercial products, but providing this information strictly as a service to our users.
Currently Available Data Tools
HDF, HDF-EOS, and other EOSDIS Science Data Processing Toolkit material
HDF-EOS and SDP Toolkit
This is the home for all releases of HDF-EOS, tools like EOSView, HEG, and the SDP Toolkit libraries used in the EOS data processing centers. HDF-EOS User Manuals can be downloaded from that site. You can use the downloading instructions below* and then change ftp directory straight to what you need.
HDF
The home of the HDF group at the National Center for Supercomputing Applications (NCSA). Find the new HDF5, and many new precompiled command-line utilities. |
HDFView is a visual tool for browsing and editing NCSA HDF4 and HDF5 files. Using HDFView, you can:
- View a file hierarchy in a tree structure
- Create new file, add or delete groups and datasets
- View and modify the content of a dataset
- Add, delete and modify attributes
- Replace I/O and GUI components such as table view, image view and metadata view

HDFLook is a multifunctional GES DAAC data processing and visualization tool for MODIS (Radiometric and Geolocation, Atmosphere, Ocean and Land data) and AIRS L1B data. HDFLook is a result of joint collaboration between LOA USTL, France, and NASA GES DAAC and is based on the very popular MSPHINX tool philosophy. Created as a flexible modular tool, it is easy to update and add new features, and is free.

Sample TRMM reader software.
The program in the tar package is an enhanced version of the original READTRMM software (select_vNsds). The functionalities added include options to choose ASCII output format and running the program in batch mode, that is, processing multiple input data files by issuing a single command. Currently the program consists only the C version, and has been tested only on SGI IRIX 5.3, 6.4 and Linux machines.

This UARS read software program reads and dumps the contents of all UARS level 3A data files (3AL, 3AT, 3LP, 3TP, 3AS/3BS, and UARS Correlative). The input file may be either the actual data file (PROD extension) or the metadata file (META extension). Output can be redirected to an ASCII file. Subsetting by latitude and vertical height can also be done.
