Tools and Services
The following data tools and services are provided as aids to help users fully utilize and manipulate DAAC data products. The Data Services listed below are applications that manipulate DAAC data on DAAC servers. The Data Tools that are listed are "desktop" applications that users run on their local machines.
Those tools and services listed here have been researched, tested, and enhanced if needed to handle the HDF and HDF-EOS data formats. Most of this software is freely available and can be downloaded via the Web. The HDF-EOS Tools and Information Center provides links to additional tools and resources that are not listed on this page, but that you may find to be useful. We encourage you to send us information about your tools and the types of applications and data sets you use. NASA is not endorsing any of the commercial products, but providing this information strictly as a service to our users.
